[0004] Conventional traffic signal control systems switch signals based on fixed programs, which means they cannot flexibly respond to fluctuations in traffic volume. This results in frequent traffic congestion and makes it difficult for emergency vehicles to pass quickly. Unnecessary signal stops also increase energy consumption and have a negative impact on the environment. To solve these issues, a system is needed that can collect and analyze traffic data in real time and automatically generate optimal signal patterns. [Means for solving the problem]
[0005] The present invention provides a system in which multiple traffic control devices collect traffic data and transmit that data to a central processing unit. The central processing unit performs traffic analysis based on the collected traffic data and generates efficient signal patterns based on the analysis results. Furthermore, the system has the ability to simulate these signal patterns in advance using digital twin technology. Once the optimal signal pattern is determined, it is transmitted to each traffic control device, allowing signals to be flexibly controlled according to actual traffic conditions. This reduces traffic congestion, allows emergency vehicles to pass more quickly, reduces energy consumption, and reduces environmental impact.

[0009] "Traffic analysis" is the process of evaluating traffic flow, congestion, and other characteristics based on collected traffic data.

In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."
[0036] The present invention realizes a series of processes in a traffic control system, in which multiple traffic control devices (terminals) collect traffic data in real time, a central processing unit (server) performs traffic analysis based on that data, and automatically generates optimal signal patterns. Specific embodiments are described below with examples.
[0037] System configuration
[0038] The main components of this system are as follows:
[0039] Traffic control device (terminal)
[0040] Central Processing Unit (Server)
[0041] network
[0042] Traffic control devices (terminals) are installed at each intersection and use sensors to collect traffic data in real time, which is then transmitted to a central processing unit (server) via a network.
[0043] Program processing
[0044] The specific operations of the server and the terminal will be explained step by step below.
[0045] Traffic data collection
[0046] The terminals use built-in sensors to collect traffic data such as the number of vehicles, their speeds, vehicle types, road occupancy rates, etc. For example, a terminal installed at an intersection counts the number of vehicles passing by every second and transmits this information to a central processing unit (server) in real time.
[0047] Traffic data analysis
[0048] The server receives traffic data from multiple devices and stores it in a database. It then uses AI algorithms to perform traffic analysis. For example, it can analyze the phenomenon of a sudden increase in vehicle traffic at a particular intersection and identify the cause of congestion.
[0049] Signal pattern generation and simulation
[0050] The server generates optimal signal patterns based on the analysis results. These patterns are then simulated using digital twin technology to evaluate how the modified patterns will affect actual traffic conditions. For example, it is possible to confirm in advance how traffic flow and emergency vehicle transit times will be reduced if a new signal pattern is applied.
[0051] Applying signal patterns
[0052] Based on the results of the simulation, the server determines the most effective signal pattern and sends it to each device. The device then controls the signals according to the received signal pattern, thereby optimizing traffic flow. For example, at intersection A, which was causing congestion, the red light time could be shortened and the green light time extended, alleviating congestion.
[0053] Traffic situation monitoring and feedback
[0054] The server continues to monitor traffic conditions in real time after the signal pattern change and makes further adjustments as needed, ensuring optimal traffic flow at all times. For example, signal patterns can be changed instantly in response to unexpected accidents or emergency vehicles passing by.
[0055] Specific examples
[0056] Traffic jams frequently occurred at intersection A in a certain city during the morning rush hour. Conventional fixed programs could not resolve this congestion, but by introducing this system, the following steps were implemented:
[0057] 1. The terminal collected traffic data at intersection A every second and sent it to the server.
[0058] 2. The server performed traffic analysis based on the collected data and determined that the cause of the traffic jam was the length of the red light.
[0059] 3. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[0060] 4. Since the simulation was successful, the optimal signal pattern was sent to the terminal and implemented at intersection A.
[0061] 5. Users saw that traffic congestion had eased and used this data for urban planning.
[0062] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, and reduce the environmental load.
[0063] The processing flow will be explained below.
[0064] Step 1: Collecting traffic data
[0065] The device uses sensors to collect real-time traffic data, such as the number of vehicles, their speed, vehicle type, and road occupancy rate, every second. This data is temporarily stored on the device.
[0066] Step 2: Sending traffic data
[0067] The terminals transmit the collected traffic data to a central processing unit (server) via a network. The transmission interval is real-time, so the latest data is updated every second.
[0068] Step 3: Aggregating traffic data
[0069] The server receives traffic data sent from multiple devices and stores it in a database, enabling real-time centralized management of traffic conditions across the city.
[0070] Step 4: Analyze traffic data
[0071] The server analyzes the collected traffic data using AI algorithms. Specifically, it identifies traffic flow and congestion factors based on past and current data. It also analyzes traffic fluctuation patterns due to time of day and specific events.
[0072] Step 5: Generate signal patterns
[0073] The server generates optimal signal patterns based on the results of traffic analysis, taking into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, and improving energy efficiency.
[0074] Step 6: Simulation with the digital twin
[0075] The server then uses digital twin technology to simulate the generated traffic signal patterns. Specifically, it applies the traffic signal patterns in a virtual environment and evaluates the resulting traffic flow, waiting times, accident risk, and other factors.
[0076] Step 7: Determine the optimal pattern
[0077] The server determines the most effective traffic light pattern based on the simulation results, taking into account the positive effects shown by the simulation (e.g., reduced congestion, shorter transit times for emergency vehicles).
[0078] Step 8: Sending a signal pattern
[0079] The server then transmits the optimal signal pattern to each terminal in real time, and the pattern is immediately reflected in signal control.
[0080] Step 9: Applying the signal pattern
[0081] The terminal controls the traffic light based on the received new signal pattern, for example, shortening the red light time and extending the green light time.
[0082] Step 10: Traffic monitoring
[0083] The server continues to monitor traffic conditions in real time after the signal pattern changes to ensure that the changes are having the intended effect and make further adjustments if necessary.
[0084] Step 11: Data Feedback
[0085] The server analyzes traffic data and generates a report on the effectiveness of the system. This data is used for future urban planning and further system optimization. Users (urban planners) can use this data to consider improvements and new plans.

[0087] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."
[0088] Conventional traffic control systems rely on fixed programs to control traffic signals, lacking the flexibility to respond to real-time changes. This makes it difficult to respond quickly to traffic congestion or the passage of emergency vehicles, making it difficult to improve traffic efficiency or reduce energy consumption. Furthermore, the use of simulation technology was insufficient, making it difficult to verify the effectiveness of the generated signal patterns in advance.
[0089] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.
[0090] In this invention, the server includes means for collecting traffic data, means for performing traffic analysis based on the traffic data, means for generating efficient signal patterns based on the results of the traffic analysis, means for simulating the generated signal patterns using digital twin technology, and means for monitoring traffic conditions after the signal patterns are applied and providing feedback. This enables flexible signal control in accordance with traffic conditions in real time, thereby realizing the alleviation of traffic congestion, the rapid passage of emergency vehicles, reduction of energy consumption, and reduction of environmental impact.

[0126] The flow of the identification process in the first embodiment will be described with reference to FIG.
[0127] Processing flow
[0128] Step 1: Collecting traffic data
[0129] The device uses built-in sensors to collect real-time traffic data such as the number of vehicles at intersections, their speeds, vehicle types, and road occupancy rates. For example, the device counts the number of vehicles passing by every second and stores this information in its internal memory.
[0130] Input: Traffic sensor data
[0131] Output: Collected traffic data
[0132] Step 2: Sending traffic data
[0133] The terminal sends the collected traffic data to the server via the network. Specifically, the terminal uses the HTTP protocol to send a POST request to the server API in JSON format for the collected data.
[0134] Input: Collected traffic data
[0135] Output: Traffic data sent to the server
[0136] Step 3: Save traffic data

[0207] This system will help alleviate traffic congestion, allow emergency vehicles to pass through more quickly, reduce energy consumption, and lighten the burden on the environment.
[0208] The flow of the specific processing in the application example 1 will be described with reference to FIG.
[0209] Step 1:
[0210] Traffic data collection and transmission
[0211] The terminal collects real-time traffic data such as the number of vehicles, their speed, vehicle type, and road occupancy rate from sensors installed at intersections. This data is collected every second and sent to a server via a network. The input data is electrical signal data output by the sensors, and the output is traffic data in JSON format sent to the server.
[0212] Step 2:
[0213] Traffic data analysis
[0214] The server receives traffic data sent from multiple traffic control devices in bulk and stores it in a database. Next, it performs traffic analysis using AI algorithms. In the analysis step, the collected traffic situation data is used as input data, and a series of data processing and data calculations (for example, counting the number of vehicles and calculating average speeds) are performed. The output is an analysis of the causes of traffic congestion and prediction data.
[0215] Step 3:
[0216] Signal pattern generation
[0217] The server automatically generates the optimal traffic light pattern based on the analysis results. The input in this step is the traffic analysis results, and the output is the newly generated traffic light pattern. Specifically, it calculates the time allocation of red and green lights.
[0218] Step 4:
[0219] Simulation and Evaluation
[0220] The generated signal patterns are simulated in a virtual environment using digital twin technology. This simulation evaluates how the signal patterns affect real-world traffic conditions. The input data is the signal patterns generated in the previous step, and the output data is the evaluation results based on the simulation.
[0221] Step 5:
[0222] Applying and transmitting signal patterns
[0223] The server determines the optimal signal pattern based on the simulation results and sends it to each terminal. The input at this stage is the simulation results, and the output is the data of the final signal pattern. The actual traffic lights are controlled according to the signal pattern sent to the terminal.
[0224] Step 6:
[0225] Providing data to autonomous vehicles
[0226] The signal patterns and traffic condition data sent from the terminal are provided to the autonomous vehicle in real time. The vehicle monitors the surrounding traffic conditions based on the received traffic data and is then suggested the optimal driving route. The input is data from the traffic control device, and the output is driving instruction data used by the autonomous driving system.
[0227] Step 7:
[0228] Emergency response
[0229] When an emergency vehicle approaches, the server issues instructions to the autonomous vehicle for a rapid response, including the emergency vehicle's location data and emergency response instructions. The input is the emergency vehicle's location information, and the output is data on avoidance and response instructions for the autonomous vehicle.
[0230] These steps will concretely improve traffic efficiency and the safety of autonomous vehicles.

[0232] The present invention realizes a series of processes in a traffic control system, in which user emotion data is collected by an emotion engine and the data is incorporated into traffic analysis to generate signal patterns. Specific embodiments are described below with examples.
[0233] System configuration
[0234] The main components of this system are as follows:
[0235] Traffic control device (terminal)
[0236] Central Processing Unit (Server)
[0237] Emotion Engine
[0238] network
[0239] Traffic control devices (terminals) are installed at each intersection and use sensors to collect traffic data in real time. The emotion engine has the function of collecting and analyzing user emotion data. The collected data is sent to a central processing unit (server) via a network.
[0240] Program processing
[0241] The specific operations of the server, terminal, and user will be explained step by step below.
[0242] Traffic data collection
[0243] The device uses sensors to collect real-time traffic data, such as the number of vehicles, their speed, vehicle type, and road occupancy rate, every second. This data is temporarily stored on the device.
[0244] Collecting Emotional Data
[0245] The emotion engine collects user emotional data in real time based on biometric information, facial expression analysis, etc. For example, it analyzes the user's facial expressions using an in-car camera to evaluate the level of stress and irritation.
[0246] Transmission of traffic and emotion data
[0247] The terminal transmits the collected traffic data and emotion data collected by the emotion engine to a central processing unit (server) via a network. The transmission interval is real-time, so the latest data is updated every second.
[0248] Aggregation of traffic and emotion data
[0249] The server receives all the data sent from multiple devices and emotion engines and stores it in a database, enabling real-time centralized management of traffic conditions and users' emotional states across the city.
[0250] Traffic and emotion data analysis
[0251] The server uses AI algorithms to analyze the collected traffic and emotion data. Specifically, it identifies traffic flow, factors behind congestion, and patterns of user emotion change based on past and current data. It also analyzes the correlation between traffic and emotion based on time of day and specific events.
[0252] Signal pattern generation and simulation
[0253] The server then generates optimal traffic light patterns based on the analysis results. These patterns take into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, improving energy efficiency, and reducing user stress. The generated traffic light patterns are then simulated using digital twin technology to evaluate how the changed patterns will affect actual traffic conditions and user emotions.
[0254] Applying signal patterns
[0255] The server determines the most effective traffic signal pattern based on the simulation results and sends it to each device. The device then controls the traffic signals according to the received signal pattern, thereby optimizing traffic flow.
[0256] Monitoring traffic conditions and user emotions
[0257] The server continues to monitor traffic conditions and users' emotional state in real time after the signal pattern change and makes further adjustments as needed, thereby always maintaining optimal traffic flow and user comfort.
[0258] Specific examples
[0259] Traffic jams frequently occurred at intersection A in a certain city during the morning rush hour. Conventional fixed programs could not resolve this congestion, but by introducing this system, the following steps were implemented:
[0260] 1. The terminal collected traffic data at intersection A every second and sent it to the server.
[0261] 2. The emotion engine analyzed the facial expressions of the user inside the car, measured their stress level, and sent the data to the server.
[0262] 3. The server performed traffic analysis and sentiment analysis based on the collected data to identify the causes of traffic congestion and factors that cause user stress.
[0263] 4. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[0264] 5. The simulation was successful, so the optimal signal pattern was sent to the terminal and implemented at intersection A.
[0265] 6. As traffic congestion eased, users saw their stress levels drop, and they used this data for urban planning.
[0266] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, ease environmental load, and improve user comfort.
[0267] The processing flow will be explained below.
[0268] Step 1: Collecting traffic data
[0269] The device collects real-time traffic data using sensors installed at each intersection, specifically information such as the number of vehicles, speed, vehicle type, and road occupancy rate, which is acquired every second and temporarily stored in its internal memory.
[0270] Step 2: Collecting emotion data
[0271] The emotion engine collects biometric information such as facial expressions, voice, and heart rate from the user interface and camera, and analyzes this information to obtain emotional data about the user. For example, it can analyze video footage from an in-car camera and quantify the user's stress level and frustration.
[0272] Step 3: Sending traffic and emotion data
[0273] The terminals and emotion engines each send the collected traffic data and emotion data to a central processing unit (server) via a network. This transmission is done in real time, with the latest data being sent from each terminal to the server every second.
[0274] Step 4: Aggregating traffic and sentiment data
[0275] The server receives all the data sent from multiple devices and emotion engines and stores it in a database. By aggregating this data, it is possible to centrally manage traffic conditions and users' emotional states throughout the city in real time.
[0276] Step 5: Analyzing traffic and emotion data
[0277] The server uses AI algorithms to analyze the collected traffic and emotion data. Specifically, it compares it with past data to identify traffic flow, causes of congestion, and patterns of user emotion change. It also analyzes correlations between traffic and emotion based on time of day or specific events.
[0278] Step 6: Generate and simulate signal patterns
[0279] The server generates optimal signal patterns based on the results of traffic and emotion analysis. These signal patterns are then simulated in a virtual environment using digital twin technology to evaluate how the modified patterns affect actual traffic conditions and user emotions.
[0280] Step 7: Determine the optimal pattern
[0281] Based on the simulation results, the server determines the most effective traffic signal pattern, which aims to reduce traffic congestion, shorten transit times for emergency vehicles, improve energy efficiency, and reduce user stress.
[0282] Step 8: Sending a signal pattern
[0283] The server then transmits the determined optimal signal pattern to each terminal in real time, so that the signal pattern is immediately applied.
[0284] Step 9: Applying the signal pattern
[0285] The device then controls the traffic lights based on the new signal pattern received, for example by shortening the red light time and extending the green light time.
[0286] Step 10: Monitoring traffic conditions and user emotions
[0287] The server continues to monitor traffic conditions and user sentiment in real time after the signal pattern change, allowing it to assess whether the changes are having the desired effect and make further adjustments if necessary.
[0288] Step 11: Data Feedback
[0289] The server generates a report based on the traffic conditions and user sentiment data and provides the results as feedback to urban planners (users), who can use the data to improve future transportation planning and systems.

In the following description, the data processing device 12 will be referred to as the "server" and the smart glasses 214 will be referred to as the "terminal."
[0478] The present invention realizes a series of processes in a traffic control system, in which multiple traffic control devices (terminals) collect traffic data in real time, a central processing unit (server) performs traffic analysis based on that data, and automatically generates optimal signal patterns. Specific embodiments are described below with examples.
[0479] System configuration
[0480] The main components of this system are as follows:
[0481] Traffic control device (terminal)
[0482] Central Processing Unit (Server)
[0483] network
[0484] Traffic control devices (terminals) are installed at each intersection and use sensors to collect traffic data in real time, which is then transmitted to a central processing unit (server) via a network.
[0485] Program processing
[0486] The specific operations of the server and the terminal will be explained step by step below.
[0487] Traffic data collection
[0488] The terminals use built-in sensors to collect traffic data such as the number of vehicles, their speeds, vehicle types, road occupancy rates, etc. For example, a terminal installed at an intersection counts the number of vehicles passing by every second and transmits this information to a central processing unit (server) in real time.
[0489] Traffic data analysis
[0490] The server receives traffic data from multiple devices and stores it in a database. It then uses AI algorithms to perform traffic analysis. For example, it can analyze the phenomenon of a sudden increase in vehicle traffic at a particular intersection and identify the cause of congestion.
[0491] Signal pattern generation and simulation
[0492] The server generates optimal signal patterns based on the analysis results. These patterns are then simulated using digital twin technology to evaluate how the modified patterns will affect actual traffic conditions. For example, it is possible to confirm in advance how traffic flow and emergency vehicle transit times will be reduced if a new signal pattern is applied.
[0493] Applying signal patterns
[0494] Based on the results of the simulation, the server determines the most effective signal pattern and sends it to each device. The device then controls the signals according to the received signal pattern, thereby optimizing traffic flow. For example, at intersection A, which was causing congestion, the red light time could be shortened and the green light time extended, alleviating congestion.
[0495] Traffic situation monitoring and feedback
[0496] The server continues to monitor traffic conditions in real time after the signal pattern change and makes further adjustments as needed, ensuring optimal traffic flow at all times. For example, signal patterns can be changed instantly in response to unexpected accidents or emergency vehicles passing by.
[0497] Specific examples
[0498] Traffic jams frequently occurred at intersection A in a certain city during the morning rush hour. Conventional fixed programs could not resolve this congestion, but by introducing this system, the following steps were implemented:
[0499] 1. The terminal collected traffic data at intersection A every second and sent it to the server.
[0500] 2. The server performed traffic analysis based on the collected data and determined that the cause of the traffic jam was the length of the red light.
[0501] 3. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[0502] 4. Since the simulation was successful, the optimal signal pattern was sent to the terminal and implemented at intersection A.
[0503] 5. Users saw that traffic congestion had eased and used this data for urban planning.
[0504] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, and reduce the environmental load.
[0505] The processing flow will be explained below.
[0506] Step 1: Collecting traffic data
[0507] The device uses sensors to collect real-time traffic data, such as the number of vehicles, their speed, vehicle type, and road occupancy rate, every second. This data is temporarily stored on the device.
[0508] Step 2: Sending traffic data
[0509] The terminals transmit the collected traffic data to a central processing unit (server) via a network. The transmission interval is real-time, so the latest data is updated every second.
[0510] Step 3: Aggregating traffic data
[0511] The server receives traffic data sent from multiple devices and stores it in a database, enabling real-time centralized management of traffic conditions across the city.
[0512] Step 4: Analyze traffic data
[0513] The server analyzes the collected traffic data using AI algorithms. Specifically, it identifies traffic flow and congestion factors based on past and current data. It also analyzes traffic fluctuation patterns due to time of day and specific events.
[0514] Step 5: Generate signal patterns
[0515] The server generates optimal signal patterns based on the results of traffic analysis, taking into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, and improving energy efficiency.
[0516] Step 6: Simulation with the digital twin
[0517] The server then uses digital twin technology to simulate the generated traffic signal patterns. Specifically, it applies the traffic signal patterns in a virtual environment and evaluates the resulting traffic flow, waiting times, accident risk, and other factors.
[0518] Step 7: Determine the optimal pattern
[0519] The server determines the most effective traffic light pattern based on the simulation results, taking into account the positive effects shown by the simulation (e.g., reduced congestion, shorter transit times for emergency vehicles).
[0520] Step 8: Sending a signal pattern
[0521] The server then transmits the optimal signal pattern to each terminal in real time, and the pattern is immediately reflected in signal control.
[0522] Step 9: Applying the signal pattern
[0523] The terminal controls the traffic light based on the received new signal pattern, for example, shortening the red light time and extending the green light time.
[0524] Step 10: Traffic monitoring
[0525] The server continues to monitor traffic conditions in real time after the signal pattern changes to ensure that the changes are having the intended effect and make further adjustments if necessary.
[0526] Step 11: Data Feedback
[0527] The server analyzes traffic data and generates a report on the effectiveness of the system. This data is used for future urban planning and further system optimization. Users (urban planners) can use this data to consider improvements and new plans.

[0530] Conventional traffic control systems rely on fixed programs to control traffic signals, lacking the flexibility to respond to real-time changes. This makes it difficult to respond quickly to traffic congestion or the passage of emergency vehicles, making it difficult to improve traffic efficiency or reduce energy consumption. Furthermore, the use of simulation technology was insufficient, making it difficult to verify the effectiveness of the generated signal patterns in advance.
[0531] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.
[0532] In this invention, the server includes means for collecting traffic data, means for performing traffic analysis based on the traffic data, means for generating efficient signal patterns based on the results of the traffic analysis, means for simulating the generated signal patterns using digital twin technology, and means for monitoring traffic conditions after the signal patterns are applied and providing feedback. This enables flexible signal control in accordance with traffic conditions in real time, thereby realizing the alleviation of traffic congestion, the rapid passage of emergency vehicles, reduction of energy consumption, and reduction of environmental impact.

[0656] The server receives traffic data sent from multiple traffic control devices in bulk and stores it in a database. Next, it performs traffic analysis using AI algorithms. In the analysis step, the collected traffic situation data is used as input data, and a series of data processing and data calculations (for example, counting the number of vehicles and calculating average speeds) are performed. The output is an analysis of the causes of traffic congestion and prediction data.
[0657] Step 3:

[0659] The server automatically generates the optimal traffic light pattern based on the analysis results. The input in this step is the traffic analysis results, and the output is the newly generated traffic light pattern. Specifically, it calculates the time allocation of red and green lights.
[0660] Step 4:

The input at this stage is the simulation results, and the output is the data of the final signal pattern. The actual traffic lights are controlled according to the signal pattern sent to the terminal.
[0666] Step 6:
[0667] Providing data to autonomous vehicles
[0668] The signal patterns and traffic condition data sent from the terminal are provided to the autonomous vehicle in real time. The vehicle monitors the surrounding traffic conditions based on the received traffic data and is then suggested the optimal driving route. The input is data from the traffic control device, and the output is driving instruction data used by the autonomous driving system.
[0669] Step 7:
[0670] Emergency response
[0671] When an emergency vehicle approaches, the server issues instructions to the autonomous vehicle for a rapid response, including the emergency vehicle's location data and emergency response instructions. The input is the emergency vehicle's location information, and the output is data on avoidance and response instructions for the autonomous vehicle.
[0672] These steps will concretely improve traffic efficiency and the safety of autonomous vehicles.

[0687] The emotion engine collects user emotional data in real time based on biometric information, facial expression analysis, etc. For example, it analyzes the user's facial expressions using an in-car camera to evaluate the level of stress and irritation.
[0688] Transmission of traffic and emotion data
[0689] The terminal transmits the collected traffic data and emotion data collected by the emotion engine to a central processing unit (server) via a network. The transmission interval is real-time, so the latest data is updated every second.
[0690] Aggregation of traffic and emotion data
[0691] The server receives all the data sent from multiple devices and emotion engines and stores it in a database, enabling real-time centralized management of traffic conditions and users' emotional states across the city.
[0692] Traffic and emotion data analysis
[0693] The server uses AI algorithms to analyze the collected traffic and emotion data. Specifically, it identifies traffic flow, factors behind congestion, and patterns of user emotion change based on past and current data. It also analyzes the correlation between traffic and emotion based on time of day and specific events.
[0694] Signal pattern generation and simulation
[0695] The server then generates optimal traffic light patterns based on the analysis results. These patterns take into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, improving energy efficiency, and reducing user stress. The generated traffic light patterns are then simulated using digital twin technology to evaluate how the changed patterns will affect actual traffic conditions and user emotions.
[0696] Applying signal patterns

[0702] 1. The terminal collected traffic data at intersection A every second and sent it to the server.
[0703] 2. The emotion engine analyzed the facial expressions of the user inside the car, measured their stress level, and sent the data to the server.
[0704] 3. The server performed traffic analysis and sentiment analysis based on the collected data to identify the causes of traffic congestion and factors that cause user stress.
[0705] 4. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[0706] 5. The simulation was successful, so the optimal signal pattern was sent to the terminal and implemented at intersection A.
[0707] 6. As traffic congestion eased, users saw their stress levels drop, and they used this data for urban planning.
[0708] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, ease environmental load, and improve user comfort.
[0709] The processing flow will be explained below.
[0710] Step 1: Collecting traffic data
[0711] The device collects real-time traffic data using sensors installed at each intersection, specifically information such as the number of vehicles, speed, vehicle type, and road occupancy rate, which is acquired every second and temporarily stored in its internal memory.
[0712] Step 2: Collecting emotion data
[0713] The emotion engine collects biometric information such as facial expressions, voice, and heart rate from the user interface and camera, and analyzes this information to obtain emotional data about the user. For example, it can analyze video footage from an in-car camera and quantify the user's stress level and frustration.
[0714] Step 3: Sending traffic and emotion data
[0715] The terminals and emotion engines each send the collected traffic data and emotion data to a central processing unit (server) via a network. This transmission is done in real time, with the latest data being sent from each terminal to the server every second.
[0716] Step 4: Aggregating traffic and sentiment data
[0717] The server receives all the data sent from multiple devices and emotion engines and stores it in a database. By aggregating this data, it is possible to centrally manage traffic conditions and users' emotional states throughout the city in real time.
[0718] Step 5: Analyzing traffic and emotion data
[0719] The server uses AI algorithms to analyze the collected traffic and emotion data. Specifically, it compares it with past data to identify traffic flow, causes of congestion, and patterns of user emotion change. It also analyzes correlations between traffic and emotion based on time of day or specific events.
[0720] Step 6: Generate and simulate signal patterns
[0721] The server generates optimal signal patterns based on the results of traffic and emotion analysis. These signal patterns are then simulated in a virtual environment using digital twin technology to evaluate how the modified patterns affect actual traffic conditions and user emotions.
[0722] Step 7: Determine the optimal pattern
[0723] Based on the simulation results, the server determines the most effective traffic signal pattern, which aims to reduce traffic congestion, shorten transit times for emergency vehicles, improve energy efficiency, and reduce user stress.
[0724] Step 8: Sending a signal pattern
[0725] The server then transmits the determined optimal signal pattern to each terminal in real time, so that the signal pattern is immediately applied.
[0726] Step 9: Applying the signal pattern
[0727] The device then controls the traffic lights based on the new signal pattern received, for example by shortening the red light time and extending the green light time.
[0728] Step 10: Monitoring traffic conditions and user emotions
[0729] The server continues to monitor traffic conditions and user sentiment in real time after the signal pattern change, allowing it to assess whether the changes are having the desired effect and make further adjustments if necessary.
[0730] Step 11: Data Feedback
[0731] The server generates a report based on the traffic conditions and user sentiment data and provides the results as feedback to urban planners (users), who can use the data to improve future transportation planning and systems.

[0741] "Signal pattern" refers to data that indicates the time allocation of red and green traffic lights and the timing of their switching.
[0742] "Analysis" refers to the process of using AI algorithms and other methods to identify traffic flow, factors behind congestion, and patterns of user emotion change based on collected traffic and emotion data.
[0743] "Digital twin technology" is a technology that digitally reproduces and simulates physical systems and environments.

[0920] The present invention realizes a series of processes in a traffic control system, in which multiple traffic control devices (terminals) collect traffic data in real time, a central processing unit (server) performs traffic analysis based on that data, and automatically generates optimal signal patterns. Specific embodiments are described below with examples.
[0921] System configuration
[0922] The main components of this system are as follows:
[0923] Traffic control device (terminal)
[0924] Central Processing Unit (Server)
[0925] network
[0926] Traffic control devices (terminals) are installed at each intersection and use sensors to collect traffic data in real time, which is then transmitted to a central processing unit (server) via a network.
[0927] Program processing
[0928] The specific operations of the server and the terminal will be explained step by step below.
[0929] Traffic data collection
[0930] The terminals use built-in sensors to collect traffic data such as the number of vehicles, their speeds, vehicle types, road occupancy rates, etc. For example, a terminal installed at an intersection counts the number of vehicles passing by every second and transmits this information to a central processing unit (server) in real time.
[0931] Traffic data analysis
[0932] The server receives traffic data from multiple devices and stores it in a database. It then uses AI algorithms to perform traffic analysis. For example, it can analyze the phenomenon of a sudden increase in vehicle traffic at a particular intersection and identify the cause of congestion.
[0933] Signal pattern generation and simulation
[0934] The server generates optimal signal patterns based on the analysis results. These patterns are then simulated using digital twin technology to evaluate how the modified patterns will affect actual traffic conditions. For example, it is possible to confirm in advance how traffic flow and emergency vehicle transit times will be reduced if a new signal pattern is applied.
[0935] Applying signal patterns
[0936] Based on the results of the simulation, the server determines the most effective signal pattern and sends it to each device. The device then controls the signals according to the received signal pattern, thereby optimizing traffic flow. For example, at intersection A, which was causing congestion, the red light time could be shortened and the green light time extended, alleviating congestion.
[0937] Traffic situation monitoring and feedback
[0938] The server continues to monitor traffic conditions in real time after the signal pattern change and makes further adjustments as needed, ensuring optimal traffic flow at all times. For example, signal patterns can be changed instantly in response to unexpected accidents or emergency vehicles passing by.
[0939] Specific examples
[0940] Traffic jams frequently occurred at intersection A in a certain city during the morning rush hour. Conventional fixed programs could not resolve this congestion, but by introducing this system, the following steps were implemented:
[0941] 1. The terminal collected traffic data at intersection A every second and sent it to the server.
[0942] 2. The server performed traffic analysis based on the collected data and determined that the cause of the traffic jam was the length of the red light.
[0943] 3. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[0944] 4. Since the simulation was successful, the optimal signal pattern was sent to the terminal and implemented at intersection A.
[0945] 5. Users saw that traffic congestion had eased and used this data for urban planning.
[0946] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, and reduce the environmental load.
[0947] The processing flow will be explained below.
[0948] Step 1: Collecting traffic data
[0949] The device uses sensors to collect real-time traffic data, such as the number of vehicles, their speed, vehicle type, and road occupancy rate, every second. This data is temporarily stored on the device.
[0950] Step 2: Sending traffic data
[0951] The terminals transmit the collected traffic data to a central processing unit (server) via a network. The transmission interval is real-time, so the latest data is updated every second.
[0952] Step 3: Aggregating traffic data
[0953] The server receives traffic data sent from multiple devices and stores it in a database, enabling real-time centralized management of traffic conditions across the city.
[0954] Step 4: Analyze traffic data
[0955] The server analyzes the collected traffic data using AI algorithms. Specifically, it identifies traffic flow and congestion factors based on past and current data. It also analyzes traffic fluctuation patterns due to time of day and specific events.
[0956] Step 5: Generate signal patterns
[0957] The server generates optimal signal patterns based on the results of traffic analysis, taking into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, and improving energy efficiency.
[0958] Step 6: Simulation with the digital twin
[0959] The server then uses digital twin technology to simulate the generated traffic signal patterns. Specifically, it applies the traffic signal patterns in a virtual environment and evaluates the resulting traffic flow, waiting times, accident risk, and other factors.
[0960] Step 7: Determine the optimal pattern
[0961] The server determines the most effective traffic light pattern based on the simulation results, taking into account the positive effects shown by the simulation (e.g., reduced congestion, shorter transit times for emergency vehicles).
[0962] Step 8: Sending a signal pattern
[0963] The server then transmits the optimal signal pattern to each terminal in real time, and the pattern is immediately reflected in signal control.
[0964] Step 9: Applying the signal pattern
[0965] The terminal controls the traffic light based on the received new signal pattern, for example, shortening the red light time and extending the green light time.
[0966] Step 10: Traffic monitoring
[0967] The server continues to monitor traffic conditions in real time after the signal pattern changes to ensure that the changes are having the intended effect and make further adjustments if necessary.
[0968] Step 11: Data Feedback
[0969] The server analyzes traffic data and generates a report on the effectiveness of the system. This data is used for future urban planning and further system optimization. Users (urban planners) can use this data to consider improvements and new plans.

It also analyzes the correlation between traffic and emotion based on time of day and specific events.
[1136] Signal pattern generation and simulation
[1137] The server then generates optimal traffic light patterns based on the analysis results. These patterns take into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, improving energy efficiency, and reducing user stress. The generated traffic light patterns are then simulated using digital twin technology to evaluate how the changed patterns will affect actual traffic conditions and user emotions.
[1138] Applying signal patterns
[1139] The server determines the most effective traffic signal pattern based on the simulation results and sends it to each device. The device then controls the traffic signals according to the received signal pattern, thereby optimizing traffic flow.

[1149] 6. As traffic congestion eased, users saw their stress levels drop, and they used this data for urban planning.
[1150] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, ease environmental load, and improve user comfort.
[1151] The processing flow will be explained below.
[1152] Step 1: Collecting traffic data
[1153] The device collects real-time traffic data using sensors installed at each intersection, specifically information such as the number of vehicles, speed, vehicle type, and road occupancy rate, which is acquired every second and temporarily stored in its internal memory.
[1154] Step 2: Collecting emotion data
[1155] The emotion engine collects biometric information such as facial expressions, voice, and heart rate from the user interface and camera, and analyzes this information to obtain emotional data about the user. For example, it can analyze video footage from an in-car camera and quantify the user's stress level and frustration.
[1156] Step 3: Sending traffic and emotion data
[1157] The terminals and emotion engines each send the collected traffic data and emotion data to a central processing unit (server) via a network. This transmission is done in real time, with the latest data being sent from each terminal to the server every second.
[1158] Step 4: Aggregating traffic and sentiment data
[1159] The server receives all the data sent from multiple devices and emotion engines and stores it in a database. By aggregating this data, it is possible to centrally manage traffic conditions and users' emotional states throughout the city in real time.
[1160] Step 5: Analyzing traffic and emotion data
[1161] The server uses AI algorithms to analyze the collected traffic and emotion data. Specifically, it compares it with past data to identify traffic flow, causes of congestion, and patterns of user emotion change. It also analyzes correlations between traffic and emotion based on time of day or specific events.
[1162] Step 6: Generate and simulate signal patterns
[1163] The server generates optimal signal patterns based on the results of traffic and emotion analysis. These signal patterns are then simulated in a virtual environment using digital twin technology to evaluate how the modified patterns affect actual traffic conditions and user emotions.
[1164] Step 7: Determine the optimal pattern
[1165] Based on the simulation results, the server determines the most effective traffic signal pattern, which aims to reduce traffic congestion, shorten transit times for emergency vehicles, improve energy efficiency, and reduce user stress.
[1166] Step 8: Sending a signal pattern

[1168] Step 9: Applying the signal pattern
[1169] The device then controls the traffic lights based on the new signal pattern received, for example by shortening the red light time and extending the green light time.
[1170] Step 10: Monitoring traffic conditions and user emotions
[1171] The server continues to monitor traffic conditions and user sentiment in real time after the signal pattern change, allowing it to assess whether the changes are having the desired effect and make further adjustments if necessary.
[1172] Step 11: Data Feedback

[1176] Conventional traffic control systems generate signal patterns based solely on traffic data, making it difficult to achieve optimal traffic signal control that takes into account the user's emotional state. Traffic congestion, in particular, increases user stress, ultimately affecting driving safety and comfort. Therefore, there is a demand for a system that can collect user emotional data in real time and incorporate it into traffic analysis to achieve more efficient and user-friendly traffic signal control.

[1363] The present invention realizes a series of processes in a traffic control system, in which multiple traffic control devices (terminals) collect traffic data in real time, a central processing unit (server) performs traffic analysis based on that data, and automatically generates optimal signal patterns. Specific embodiments are described below with examples.
[1364] System configuration
[1365] The main components of this system are as follows:
[1366] Traffic control device (terminal)
[1367] Central Processing Unit (Server)
[1368] network
[1369] Traffic control devices (terminals) are installed at each intersection and use sensors to collect traffic data in real time, which is then transmitted to a central processing unit (server) via a network.
[1370] Program processing
[1371] The specific operations of the server and the terminal will be explained step by step below.
[1372] Traffic data collection
[1373] The terminals use built-in sensors to collect traffic data such as the number of vehicles, their speeds, vehicle types, road occupancy rates, etc. For example, a terminal installed at an intersection counts the number of vehicles passing by every second and transmits this information to a central processing unit (server) in real time.
[1374] Traffic data analysis
[1375] The server receives traffic data from multiple devices and stores it in a database. It then uses AI algorithms to perform traffic analysis. For example, it can analyze the phenomenon of a sudden increase in vehicle traffic at a particular intersection and identify the cause of congestion.
[1376] Signal pattern generation and simulation
[1377] The server generates optimal signal patterns based on the analysis results. These patterns are then simulated using digital twin technology to evaluate how the modified patterns will affect actual traffic conditions. For example, it is possible to confirm in advance how traffic flow and emergency vehicle transit times will be reduced if a new signal pattern is applied.
[1378] Applying signal patterns
[1379] Based on the results of the simulation, the server determines the most effective signal pattern and sends it to each device. The device then controls the signals according to the received signal pattern, thereby optimizing traffic flow. For example, at intersection A, which was causing congestion, the red light time could be shortened and the green light time extended, alleviating congestion.
[1380] Traffic situation monitoring and feedback
[1381] The server continues to monitor traffic conditions in real time after the signal pattern change and makes further adjustments as needed, ensuring optimal traffic flow at all times. For example, signal patterns can be changed instantly in response to unexpected accidents or emergency vehicles passing by.
[1382] Specific examples
[1383] Traffic jams frequently occurred at intersection A in a certain city during the morning rush hour. Conventional fixed programs could not resolve this congestion, but by introducing this system, the following steps were implemented:
[1384] 1. The terminal collected traffic data at intersection A every second and sent it to the server.
[1385] 2. The server performed traffic analysis based on the collected data and determined that the cause of the traffic jam was the length of the red light.
[1386] 3. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[1387] 4. Since the simulation was successful, the optimal signal pattern was sent to the terminal and implemented at intersection A.
[1388] 5. Users saw that traffic congestion had eased and used this data for urban planning.
[1389] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, and reduce the environmental load.
[1390] The processing flow will be explained below.
[1391] Step 1: Collecting traffic data
[1392] The device uses sensors to collect real-time traffic data, such as the number of vehicles, their speed, vehicle type, and road occupancy rate, every second. This data is temporarily stored on the device.
[1393] Step 2: Sending traffic data
[1394] The terminals transmit the collected traffic data to a central processing unit (server) via a network. The transmission interval is real-time, so the latest data is updated every second.
[1395] Step 3: Aggregating traffic data
[1396] The server receives traffic data sent from multiple devices and stores it in a database, enabling real-time centralized management of traffic conditions across the city.
[1397] Step 4: Analyze traffic data
[1398] The server analyzes the collected traffic data using AI algorithms. Specifically, it identifies traffic flow and congestion factors based on past and current data. It also analyzes traffic fluctuation patterns due to time of day and specific events.
[1399] Step 5: Generate signal patterns
[1400] The server generates optimal signal patterns based on the results of traffic analysis, taking into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, and improving energy efficiency.
[1401] Step 6: Simulation with the digital twin
[1402] The server then uses digital twin technology to simulate the generated traffic signal patterns. Specifically, it applies the traffic signal patterns in a virtual environment and evaluates the resulting traffic flow, waiting times, accident risk, and other factors.
[1403] Step 7: Determine the optimal pattern
[1404] The server determines the most effective traffic light pattern based on the simulation results, taking into account the positive effects shown by the simulation (e.g., reduced congestion, shorter transit times for emergency vehicles).
[1405] Step 8: Sending a signal pattern
[1406] The server then transmits the optimal signal pattern to each terminal in real time, and the pattern is immediately reflected in signal control.
[1407] Step 9: Applying the signal pattern
[1408] The terminal controls the traffic light based on the received new signal pattern, for example, shortening the red light time and extending the green light time.
[1409] Step 10: Traffic monitoring
[1410] The server continues to monitor traffic conditions in real time after the signal pattern changes to ensure that the changes are having the intended effect and make further adjustments if necessary.
[1411] Step 11: Data Feedback
[1412] The server analyzes traffic data and generates a report on the effectiveness of the system. This data is used for future urban planning and further system optimization. Users (urban planners) can use this data to consider improvements and new plans.
[1413] Example 1
[1414] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."
[1415] Conventional traffic control systems rely on fixed programs to control traffic signals, lacking the flexibility to respond to real-time changes. This makes it difficult to respond quickly to traffic congestion or the passage of emergency vehicles, making it difficult to improve traffic efficiency or reduce energy consumption. Furthermore, the use of simulation technology was insufficient, making it difficult to verify the effectiveness of the generated signal patterns in advance.
[1416] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.
[1417] In this invention, the server includes means for collecting traffic data, means for performing traffic analysis based on the traffic data, means for generating efficient signal patterns based on the results of the traffic analysis, means for simulating the generated signal patterns using digital twin technology, and means for monitoring traffic conditions after the signal patterns are applied and providing feedback. This enables flexible signal control in accordance with traffic conditions in real time, thereby realizing the alleviation of traffic congestion, the rapid passage of emergency vehicles, reduction of energy consumption, and reduction of environmental impact.
[1418] A "terminal" is a device or system that collects and transmits traffic data to a server.
[1419] "Server" refers to a central processing unit that receives traffic data sent from terminals and analyzes and processes it.
[1420] "Traffic data" refers to information about traffic, such as the number of vehicles, their speeds, vehicle types, and road occupancy.
[1421] "Traffic analysis" is the process of analyzing traffic conditions and patterns based on collected traffic data.
[1422] "Signal pattern" refers to the timing and sequence of traffic signals set at traffic lights at intersections and other locations.
[1423] "Digital twin technology" is a technology that creates virtual models of physical systems and performs simulations and data analysis.
[1424] "Simulation" is a method of virtually recreating real-world traffic conditions and evaluating the impact of changes to traffic signal patterns in advance.
[1425] "Monitoring" is the activity of observing traffic conditions in real time and collecting data.
[1426] "Feedback" is the process of adjusting system settings and signal patterns based on monitoring results.
[1427] "Real-time" means that data is processed and results are reflected almost instantly.
[1428] "Traffic signal" refers to a signal facility installed to control the movement of vehicles and pedestrians on a road.
[1429] The present invention realizes a series of processes in a traffic control system in which multiple terminals collect traffic data in real time, a server performs traffic analysis based on that data, and automatically generates optimal signal patterns. Each component of this system and its specific operation are described in detail below.

[1530] 4. Since the simulation was successful, the optimal signal pattern was sent to the terminal and implemented at intersection A.
[1531] 5. Users saw that traffic congestion had eased and used this data for urban planning.
[1532] Prompt Sentence Examples
[1533] "Generate the optimal traffic light pattern for morning rush hour based on traffic data for intersection A. The data includes the number of vehicles, their speeds, vehicle types, and road occupancy."
[1534] This system will help alleviate traffic congestion, allow emergency vehicles to pass through more quickly, reduce energy consumption, and lighten the burden on the environment.
[1535] The flow of the specific processing in the application example 1 will be described with reference to FIG.
[1536] Step 1:
[1537] Traffic data collection and transmission
[1538] The terminal collects real-time traffic data such as the number of vehicles, their speed, vehicle type, and road occupancy rate from sensors installed at intersections. This data is collected every second and sent to a server via a network. The input data is electrical signal data output by the sensors, and the output is traffic data in JSON format sent to the server.
[1539] Step 2:
[1540] Traffic data analysis
[1541] The server receives traffic data sent from multiple traffic control devices in bulk and stores it in a database. Next, it performs traffic analysis using AI algorithms. In the analysis step, the collected traffic situation data is used as input data, and a series of data processing and data calculations (for example, counting the number of vehicles and calculating average speeds) are performed. The output is an analysis of the causes of traffic congestion and prediction data.
[1542] Step 3:
[1543] Signal pattern generation
[1544] The server automatically generates the optimal traffic light pattern based on the analysis results. The input in this step is the traffic analysis results, and the output is the newly generated traffic light pattern. Specifically, it calculates the time allocation of red and green lights.
[1545] Step 4:
[1546] Simulation and Evaluation
[1547] The generated signal patterns are simulated in a virtual environment using digital twin technology. This simulation evaluates how the signal patterns affect real-world traffic conditions. The input data is the signal patterns generated in the previous step, and the output data is the evaluation results based on the simulation.
[1548] Step 5:
[1549] Applying and transmitting signal patterns
[1550] The server determines the optimal signal pattern based on the simulation results and sends it to each terminal. The input at this stage is the simulation results, and the output is the data of the final signal pattern. The actual traffic lights are controlled according to the signal pattern sent to the terminal.
[1551] Step 6:
[1552] Providing data to autonomous vehicles
[1553] The signal patterns and traffic condition data sent from the terminal are provided to the autonomous vehicle in real time. The vehicle monitors the surrounding traffic conditions based on the received traffic data and is then suggested the optimal driving route. The input is data from the traffic control device, and the output is driving instruction data used by the autonomous driving system.
[1554] Step 7:
[1555] Emergency response
[1556] When an emergency vehicle approaches, the server issues instructions to the autonomous vehicle for a rapid response, including the emergency vehicle's location data and emergency response instructions. The input is the emergency vehicle's location information, and the output is data on avoidance and response instructions for the autonomous vehicle.
[1557] These steps will concretely improve traffic efficiency and the safety of autonomous vehicles.
[1558] Furthermore, an emotion engine that estimates the user's emotion may be further combined. That is, the identification processing unit 290 may estimate the user's emotion using the emotion identification model 59, and perform identification processing using the user's emotion.
[1559] The present invention realizes a series of processes in a traffic control system, in which user emotion data is collected by an emotion engine and the data is incorporated into traffic analysis to generate signal patterns. Specific embodiments are described below with examples.
[1560] System configuration
[1561] The main components of this system are as follows:
[1562] Traffic control device (terminal)
[1563] Central Processing Unit (Server)
[1564] Emotion Engine
[1565] network
[1566] Traffic control devices (terminals) are installed at each intersection and use sensors to collect traffic data in real time. The emotion engine has the function of collecting and analyzing user emotion data. The collected data is sent to a central processing unit (server) via a network.
[1567] Program processing
[1568] The specific operations of the server, terminal, and user will be explained step by step below.
[1569] Traffic data collection
[1570] The device uses sensors to collect real-time traffic data, such as the number of vehicles, their speed, vehicle type, and road occupancy rate, every second. This data is temporarily stored on the device.
[1571] Collecting Emotional Data
[1572] The emotion engine collects user emotional data in real time based on biometric information, facial expression analysis, etc. For example, it analyzes the user's facial expressions using an in-car camera to evaluate the level of stress and irritation.
[1573] Transmission of traffic and emotion data
[1574] The terminal transmits the collected traffic data and emotion data collected by the emotion engine to a central processing unit (server) via a network. The transmission interval is real-time, so the latest data is updated every second.
[1575] Aggregation of traffic and emotion data
[1576] The server receives all the data sent from multiple devices and emotion engines and stores it in a database, enabling real-time centralized management of traffic conditions and users' emotional states across the city.
[1577] Traffic and emotion data analysis
[1578] The server uses AI algorithms to analyze the collected traffic and emotion data. Specifically, it identifies traffic flow, factors behind congestion, and patterns of user emotion change based on past and current data. It also analyzes the correlation between traffic and emotion based on time of day and specific events.
[1579] Signal pattern generation and simulation
[1580] The server then generates optimal traffic light patterns based on the analysis results. These patterns take into consideration factors such as easing traffic congestion, shortening transit times for emergency vehicles, improving energy efficiency, and reducing user stress. The generated traffic light patterns are then simulated using digital twin technology to evaluate how the changed patterns will affect actual traffic conditions and user emotions.
[1581] Applying signal patterns
[1582] The server determines the most effective traffic signal pattern based on the simulation results and sends it to each device. The device then controls the traffic signals according to the received signal pattern, thereby optimizing traffic flow.
[1583] Monitoring traffic conditions and user emotions
[1584] The server continues to monitor traffic conditions and users' emotional state in real time after the signal pattern change and makes further adjustments as needed, thereby always maintaining optimal traffic flow and user comfort.
[1585] Specific examples
[1586] Traffic jams frequently occurred at intersection A in a certain city during the morning rush hour. Conventional fixed programs could not resolve this congestion, but by introducing this system, the following steps were implemented:
[1587] 1. The terminal collected traffic data at intersection A every second and sent it to the server.
[1588] 2. The emotion engine analyzed the facial expressions of the user inside the car, measured their stress level, and sent the data to the server.
[1589] 3. The server performed traffic analysis and sentiment analysis based on the collected data to identify the causes of traffic congestion and factors that cause user stress.
[1590] 4. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[1591] 5. The simulation was successful, so the optimal signal pattern was sent to the terminal and implemented at intersection A.
[1592] 6. As traffic congestion eased, users saw their stress levels drop, and they used this data for urban planning.
[1593] In this way, the traffic control system of the present invention can alleviate traffic congestion, allow emergency vehicles to pass quickly, reduce energy consumption, ease environmental load, and improve user comfort.
[1594] The processing flow will be explained below.
[1595] Step 1: Collecting traffic data
[1596] The device collects real-time traffic data using sensors installed at each intersection, specifically information such as the number of vehicles, speed, vehicle type, and road occupancy rate, which is acquired every second and temporarily stored in its internal memory.
[1597] Step 2: Collecting emotion data
[1598] The emotion engine collects biometric information such as facial expressions, voice, and heart rate from the user interface and camera, and analyzes this information to obtain emotional data about the user. For example, it can analyze video footage from an in-car camera and quantify the user's stress level and frustration.
[1599] Step 3: Sending traffic and emotion data
[1600] The terminals and emotion engines each send the collected traffic data and emotion data to a central processing unit (server) via a network. This transmission is done in real time, with the latest data being sent from each terminal to the server every second.
[1601] Step 4: Aggregating traffic and sentiment data
[1602] The server receives all the data sent from multiple devices and emotion engines and stores it in a database. By aggregating this data, it is possible to centrally manage traffic conditions and users' emotional states throughout the city in real time.
[1603] Step 5: Analyzing traffic and emotion data
[1604] The server uses AI algorithms to analyze the collected traffic and emotion data. Specifically, it compares it with past data to identify traffic flow, causes of congestion, and patterns of user emotion change. It also analyzes correlations between traffic and emotion based on time of day or specific events.
[1605] Step 6: Generate and simulate signal patterns
[1606] The server generates optimal signal patterns based on the results of traffic and emotion analysis. These signal patterns are then simulated in a virtual environment using digital twin technology to evaluate how the modified patterns affect actual traffic conditions and user emotions.
[1607] Step 7: Determine the optimal pattern
[1608] Based on the simulation results, the server determines the most effective traffic signal pattern, which aims to reduce traffic congestion, shorten transit times for emergency vehicles, improve energy efficiency, and reduce user stress.
[1609] Step 8: Sending a signal pattern
[1610] The server then transmits the determined optimal signal pattern to each terminal in real time, so that the signal pattern is immediately applied.
[1611] Step 9: Applying the signal pattern
[1612] The device then controls the traffic lights based on the new signal pattern received, for example by shortening the red light time and extending the green light time.
[1613] Step 10: Monitoring traffic conditions and user emotions
[1614] The server continues to monitor traffic conditions and user sentiment in real time after the signal pattern change, allowing it to assess whether the changes are having the desired effect and make further adjustments if necessary.
[1615] Step 11: Data Feedback
[1616] The server generates a report based on the traffic conditions and user sentiment data and provides the results as feedback to urban planners (users), who can use the data to improve future transportation planning and systems.
[1617] Example 2

[1619] Conventional traffic control systems generate signal patterns based solely on traffic data, making it difficult to achieve optimal traffic signal control that takes into account the user's emotional state. Traffic congestion, in particular, increases user stress, ultimately affecting driving safety and comfort. Therefore, there is a demand for a system that can collect user emotional data in real time and incorporate it into traffic analysis to achieve more efficient and user-friendly traffic signal control.
[1620] The specific processing by the specific processing unit 290 of the data processing device 12 in the second embodiment is realized by the following means.
[1621] In this invention, the server includes means for performing analysis based on traffic data and emotion data, means for generating efficient signal patterns based on the analysis results, and means for monitoring traffic conditions and emotion data in real time and making further adjustments. This makes it possible to take the collected user emotion data into account in traffic analysis and generate more optimal signal patterns.

[1625] "Emotion data" is data that indicates the emotional state of the user, analyzed based on the user's biometric information, facial expressions, and the like.
[1626] "Signal pattern" refers to data that indicates the time allocation of red and green traffic lights and the timing of their switching.
[1627] "Analysis" refers to the process of using AI algorithms and other methods to identify traffic flow, factors behind congestion, and patterns of user emotion change based on collected traffic and emotion data.
[1628] "Digital twin technology" is a technology that digitally reproduces and simulates physical systems and environments.

[1711] In this invention, the server includes means for collecting and transmitting traffic data and emotion data, means for performing traffic analysis and emotion analysis based on the traffic data and emotion data, and means for generating efficient traffic signal patterns based on the results of the traffic analysis and emotion analysis, thereby making it possible to effectively alleviate traffic congestion while taking into account the emotional state of the user and provide a comfortable driving environment for the user.
[1712] A "traffic control device" is a device that has the function of collecting and transmitting traffic data.
[1713] "Traffic data" refers to information that indicates traffic conditions, including the number of vehicles, their speeds, vehicle types, road occupancy rates, and so on.
[1714] "Emotion data" is information that indicates the user's emotional state based on biometric information and facial expression analysis.
[1715] A "central processing unit" is a device that receives data sent from multiple terminals and analyzes and processes it in a unified manner.
[1716] "Emotion analysis" is a means of analyzing collected emotion data to assess the user's emotional state.
[1717] "Traffic analysis" is a method for identifying traffic flow and congestion factors based on collected traffic data.
[1718] A "signal pattern" is a schedule or algorithm that determines how traffic signals are controlled.
[1719] "Digital twin technology" is a technology that reproduces real-world physical objects and systems in a virtual environment and performs simulations.
[1720] "Simulation" is a method for virtually verifying the actual effects of a generated signal pattern.
[1721] The "optimal signal pattern" is the most effective method of traffic signal control, taking into consideration factors such as easing traffic congestion, shortening the transit time for emergency vehicles, improving energy efficiency, and reducing user stress.
[1722] The present invention realizes a series of processes in a traffic control system, in which user emotion data is collected by an emotion engine and the data is taken into account in traffic analysis to generate traffic signal patterns. Specific embodiments are described in detail below.
[1723] System configuration
[1724] The main components of this system are as follows:
[1725] Traffic control device (terminal)
[1726] Central Processing Unit (Server)
[1727] Emotion Engine
[1728] network
[1729] Traffic control devices (terminals) are installed at each intersection and use sensors to collect traffic data in real time. The emotion engine has the function of analyzing user emotion data. The collected data is sent to a central processing unit (server) via a network.
[1730] Collecting emotion and traffic data
[1731] The server includes means for collecting and transmitting both emotion data and traffic data, and means for performing traffic analysis and emotion analysis.
[1732] Hardware and software used
[1733] On-board computer: A computer system installed in a self-driving car, such as NVIDIA DRIVE.
[1734] In-car camera: A camera that captures passengers' facial expressions, such as the Logitech C920.
[1735] Sensors: LIDAR, cameras, radar, etc. are used to collect traffic data.
[1736] Network module: A network device for sending and receiving data.
[1737] Emotion engine: Uses software such as the Emotion AI SDK to analyze user emotional data.
[1738] Traffic analysis algorithm: An algorithm that analyzes traffic data using Python and TensorFlow.
[1739] Real-time database: Firebase Realtime Database, etc., is used.
[1740] Data processing procedures
[1741] 1. Traffic and emotion data collection: In-vehicle sensors collect information on surrounding traffic conditions in real time, and the Emotion AI SDK extracts emotion data from the user's facial expressions.
[1742] 2. Data transmission: The onboard computer sends the collected data to the Firebase Realtime Database.
[1743] 3. Analysis: The server analyzes the data using Python and TensorFlow to generate traffic and sentiment analysis results.
[1744] 4. Signal pattern generation: Based on the analysis results, efficient signal patterns are generated and simulated using digital twin technology.
[1745] 5. Application of optimal signal patterns: Based on the simulation results, the optimal signal patterns are sent to the onboard computer and reflected in actual traffic signal control.
[1746] Specific examples
[1747] Traffic jams frequently occurred at intersection A in a certain city during the morning rush hour. Conventional fixed programs could not resolve this congestion, but by introducing this system, the following steps were implemented:
[1748] 1. The traffic control device (terminal) collected traffic data at intersection A every second and sent it to the server.
[1749] 2. The emotion engine analyzed the facial expressions of the user inside the car, measured their stress level, and sent the data to the server.
[1750] 3. The server performed traffic analysis and sentiment analysis based on the collected data to identify the causes of traffic congestion and factors that cause user stress.
[1751] 4. The server generated a new traffic light pattern that shortened the red light time by 5 seconds and extended the green light time by 8 seconds, and performed a simulation using digital twin technology.
[1752] 5. The simulation was successful, so the optimal signal pattern was sent to the terminal and implemented at intersection A.
[1753] 6. It was confirmed that traffic congestion was alleviated and users' stress levels also decreased.
[1754] Below is an example of a prompt sentence to input to the generative AI model.
[1755] Analyze the current traffic situation based on the collected emotion data and traffic data, and generate the optimal driving route and speed pattern. If the emotion data has a high stress score, select a gentler route, and if there is traffic congestion, prioritize avoiding it. Provide the output format in JSON.
[1756] Emotion data sample: {'stress_score': 75}
[1757] Traffic data sample: {'vehicle_speed': 60, 'traffic_density': 'high'}
[1758] The flow of the specific processing in the application example 2 will be described with reference to FIG.
[1759] Step 1:
[1760] An on-board computer collects traffic and emotion data through in-car cameras and sensors.
[1761] Input: Raw data from interior cameras, LIDAR, cameras, and radar
[1762] Output: Processed data such as stress score, vehicle speed, and traffic density
[1763] How it works: The onboard camera captures passengers' facial expressions, which are then analyzed by the Emotion AI SDK to calculate a stress score. Sensors collect data on vehicle speed and traffic density and process it in real time.
[1764] Step 2:
[1765] The on-board computer sends collected emotion and traffic data to the Firebase Realtime Database in real time.
[1766] Input: Processed data obtained in step 1
[1767] Output: Data stored in Firebase Realtime Database
[1768] Specific operation: Emotion data and traffic data are sent to the Firebase Realtime Database via NVIDIA DRIVE's network function.
[1769] Step 3:
[1770] The server receives data from the Firebase Realtime Database and performs traffic analysis and sentiment analysis.
[1771] Input: Sentiment and traffic data stored in Firebase Realtime Database
[1772] Output: Analysis results (traffic flow, causes of congestion, patterns of user emotion changes)
[1773] How it works: Using Python and TensorFlow, the server analyzes traffic and emotion data and compares it with past and current data to identify trends.
[1774] Step 4:
[1775] The server generates efficient signal patterns based on the analysis results and performs simulations using digital twin technology.
[1776] Input: Analysis results obtained in step 3
[1777] Output: Simulation results and optimal signal patterns
[1778] Specific operation: Using a generative AI model, generate optimal signal patterns, perform simulations using digital twin technology, and evaluate the simulation results.
[1779] Step 5:
[1780] The server determines the optimal signal pattern based on the simulation results and sends it back to the on-board computer.
[1781] Input: Simulation results obtained in step 4
[1782] Output: Optimal signal pattern
[1783] Specific operation: The optimal signal pattern is determined and transmitted to the vehicle's onboard computer via the network.
[1784] Step 6:
[1785] An on-board computer controls the traffic lights according to the received signal patterns.
[1786] Input: Optimal signal pattern sent in step 5
[1787] Output: Actual traffic light control
[1788] Specific operation: The on-board computer controls traffic signals based on the optimal signal pattern and adjusts to actual traffic conditions.
[1789] The specific processing unit 290 transmits the result of the specific processing to the robot 414. In the robot 414, the control unit 46A causes the speaker 240 and the control target 443 to output the result of the specific processing. The microphone 238 acquires voice indicating a user input regarding the result of the specific processing. The control unit 46A transmits voice data indicating the user input acquired by the microphone 238 to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the voice data.
[1790] The data generation model 58 is a so-called generative AI (Artificial Intelligence). An example of the data generation model 58 is ChatGPT (Internet Search<URL: https: / / openai.com / blog / chatgpt> ), Gemini (Internet search <url: https: gemini.google.com ?hl="ja">) and other generation AIs. The data generation model 58 is obtained by performing deep learning on a neural network. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating voice, text data indicating text, and image data indicating an image is also input. The data generation model 58 performs inference on the input inference data in accordance with the instruction indicated by the prompt, and outputs the inference result in a data format such as voice data and text data. Here, inference refers to, for example, analysis, classification, prediction, and / or summarization.
[1791] In the above embodiment, an example was given in which the specific processing is performed by the data processing device 12, but the technology of the present disclosure is not limited to this, and the specific processing may be performed by the robot 414.
[1792] The emotion identification model 59 as an emotion engine may determine the user's emotion according to a specific mapping. Specifically, the emotion identification model 59 may determine the user's emotion according to an emotion map (see FIG. 9), which is a specific mapping. Similarly, the emotion identification model 59 may determine the robot's emotion, and the identification processing unit 290 may perform identification processing using the robot's emotion.
[1793] FIG. 9 is a diagram illustrating an emotion map 400 on which multiple emotions are mapped. In the emotion map 400, emotions are arranged in concentric circles radiating from the center. Emotions closer to the center of the concentric circles are more primitive. Emotions representing states and actions arising from a state of mind are arranged on the outer edges of the concentric circles. The concept of emotion includes both affect and mental states. Emotions generally generated from reactions occurring in the brain are arranged on the left side of the concentric circles. Emotions generally induced by situational judgment are arranged on the right side of the concentric circles. Emotions generally generated from reactions occurring in the brain and induced by situational judgment are arranged on the upper and lower sides of the concentric circles. Furthermore, the emotion of "pleasure" is arranged on the upper side of the concentric circles, and the emotion of "discomfort" is arranged on the lower side. In this way, in the emotion map 400, multiple emotions are mapped based on the structure by which emotions are generated, and emotions that tend to occur simultaneously are mapped close to each other.
[1794] These emotions are distributed in the 3 o'clock direction on emotion map 400, and typically fluctuate between relief and anxiety. In the right half of emotion map 400, situational awareness dominates over internal sensations, resulting in a sense of calm.
[1795] The inside of emotion map 400 represents what is going on in the mind, and the outside of emotion map 400 represents behavior, so the further you go outside emotion map 400, the more visible the emotions become (the more they are expressed in behavior).
[1796] Human emotions are based on various balances, such as posture and blood sugar levels. When these balances deviate from the ideal, a state of discomfort is indicated, and when they approach the ideal, a state of pleasure is indicated. Emotions can also be created for robots, automobiles, and motorcycles, based on various balances, such as posture and remaining battery life. When these balances deviate from the ideal, a state of discomfort is indicated, and when they approach the ideal, a state of pleasure is indicated. An emotion map can be generated, for example, based on Dr. Mitsuyoshi's emotion map (Research on Voice Emotion Recognition and Emotional Brain Physiological Signal Analysis Systems, Tokushima University, Doctoral Dissertation: https: / / ci.nii.ac.jp / naid / 500000375379). The left half of the emotion map lists emotions belonging to the "reaction" domain, where sensation is dominant. The right half of the emotion map lists emotions belonging to the "situation" domain, where situational awareness is dominant.
[1797] The emotion map defines two emotions that promote learning. One is a negative emotion on the situation side, around the middle of "repentance" or "reflection." In other words, this occurs when the robot experiences negative emotions such as "I never want to feel this way again" or "I don't want to be scolded again." The other is a positive emotion on the response side, around "desire." In other words, this occurs when the robot experiences positive feelings such as "I want more" or "I want to know more."
[1798] The emotion identification model 59 inputs user input into a pre-trained neural network, obtains emotion values indicating each emotion shown in the emotion map 400, and determines the user's emotion. This neural network is pre-trained based on multiple pieces of training data that are combinations of user input and emotion values indicating each emotion shown in the emotion map 400. Furthermore, this neural network is trained so that emotions that are located close to each other have similar values, as in the emotion map 900 shown in FIG. 10. FIG. 10 shows an example in which multiple emotions, "relieved," "calm," and "reassuring," have similar emotion values.
[1799] The system according to the present disclosure has been described above mainly with respect to the functions of the data processing device 12, but the system according to the present disclosure is not necessarily implemented on a server. The system according to the present disclosure may be implemented as a general information processing system. The present disclosure may be implemented, for example, as a software program running on a personal computer or an application running on a smartphone, etc. The method according to the present disclosure may be provided to users in the form of SaaS (Software as a Service).
[1800] In the above embodiment, an example was given in which the specific processing is performed by one computer 22, but the technology of the present disclosure is not limited to this, and the specific processing may be distributed and performed by a plurality of computers including the computer 22. For example, the data generation model 58 may be provided in an external device of the data processing device 12, and data may be generated in the external device in accordance with input data.
[1801] In the above embodiment, an example in which the specific processing program 56 is stored in the storage 32 has been described, but the technology of the present disclosure is not limited to this. For example, the specific processing program 56 may be stored in a portable, computer-readable, non-transitory storage medium such as a USB (Universal Serial Bus) memory. The specific processing program 56 stored in the non-transitory storage medium is installed in the computer 22 of the data processing device 12. The processor 28 executes the specific processing in accordance with the specific processing program 56.
[1802] Alternatively, the specific processing program 56 may be stored in a storage device such as a server connected to the data processing device 12 via the network 54, and the specific processing program 56 may be downloaded and installed on the computer 22 in response to a request from the data processing device 12.
[1803] It is not necessary to store all of the specific processing program 56 in a storage device such as a server connected to the data processing device 12 via the network 54, or to store all of the specific processing program 56 in the storage 32; only a portion of the specific processing program 56 may be stored.
[1804] The hardware resource for executing a specific process can be any of the following processors: An example of a processor is a CPU, which is a general-purpose processor that functions as a hardware resource for executing a specific process by executing software, i.e., a program. Another example of a processor is a dedicated electrical circuit, such as an FPGA (Field-Programmable Gate Array), a PLD (Programmable Logic Device), or an ASIC (Application Specific Integrated Circuit), which is a processor with a circuit configuration designed specifically for executing a specific process. Each processor has built-in or connected memory, and each processor uses the memory to execute the specific process.
[1805] The hardware resource that executes the specific processing may be configured with one of these various processors, or may be configured with a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, the hardware resource that executes the specific processing may be a single processor.
[1806] As an example of a system configured with a single processor, first, one processor is configured by combining one or more CPUs and software, and this processor functions as a hardware resource that executes a specific process. Second, there is a system that uses a processor that realizes the functions of an entire system including multiple hardware resources that execute a specific process on a single IC chip, as typified by SoC (System-on-a-chip). In this way, a specific process is realized using one or more of the above-mentioned various processors as hardware resources.
[1807] Furthermore, the hardware structure of these various processors can be, more specifically, an electric circuit that combines circuit elements such as semiconductor devices. The specific processing described above is merely an example. Therefore, it goes without saying that unnecessary steps may be deleted, new steps may be added, or the processing order may be rearranged, without departing from the spirit of the invention.

For example, the above description of the configuration, functions, actions, and effects is an explanation of an example of the configuration, functions, actions, and effects of the parts related to the technology of the present disclosure. Therefore, it goes without saying that unnecessary parts may be deleted, new elements may be added, or replacements may be made to the above-described description and illustrations within the scope of the gist of the technology of the present disclosure. Furthermore, to avoid confusion and facilitate understanding of the parts related to the technology of the present disclosure, the above-described description and illustrations omit explanations of common technical knowledge that do not require particular explanation to enable the implementation of the technology of the present disclosure.
