[0018] Example 1

[0019] like Figure 1 As shown, this application provides an intelligent traffic control method, the method comprising:

[0020] Step S100: Obtain the destination, which is obtained in real time through a handheld communication terminal attached to the special vehicle;

[0021] In this embodiment, the handheld communication terminal is equipped with an intuitive and easy-to-use user interface, allowing drivers or operators to easily input destination information. The handheld communication terminal includes a touchscreen, physical buttons, or voice input functionality, allowing drivers to manually input the destination address directly on the terminal. In some cases, the handheld communication terminal can automatically obtain destination information. For example, if the vehicle is responding to an emergency call, the system automatically obtains relevant location information from the emergency services system.

[0022] The handheld communication terminal uses built-in GPS or other positioning technologies to obtain the real-time location of the special vehicle. The terminal uses built-in map data to match the input destination with the specific location on the map to confirm the exact location of the destination. Once the destination is automatically matched or manually entered, the system will prompt the driver for confirmation.

[0023] Step S200: The handheld communication terminal sends the real-time route plan to the road traffic signal controller. The real-time route plan is determined by the first processing center in the handheld communication terminal by analyzing the destination and the real-time location of the special vehicle.

[0024] In the embodiments of the present application, the handheld communication terminal obtains the latitude and longitude coordinates of the special vehicle in real time through the built-in GPS receiver, thereby determining its accurate position. In addition, other positioning technologies such as Wi-Fi, Bluetooth or mobile network can also be used to improve the accuracy and reliability of positioning. In order to keep real-time tracking of the position of the vehicle, the handheld communication terminal will periodically update the position information of the vehicle.

[0025] The first processing center in the handheld communication terminal uses route planning algorithms to analyze the destination and the real-time position of the special vehicle. These algorithms take into account various factors such as road conditions, traffic flow, speed limit, estimated arrival time, etc. to generate the optimal route planning. The first processing center is also responsible for processing real-time data from GPS and other sensors. These data provide key information about the vehicle's speed, direction, acceleration, etc. which helps to generate more accurate route planning.

[0026] Based on the destination information and real-time position data, the first processing center calculates the best path from the current position to the destination. Real-time route planning also includes generating detailed navigation instructions such as turns, straight lines, lane changes, etc.

[0027] Once the real-time route planning is generated, the handheld communication terminal sends it to the road traffic signal controller through a wireless communication network such as 4G, 5G, Wi-Fi, etc.

[0028] Step S300: Match the multiple signal machines in the real-time route planning through the second processing center in the road traffic signal controller;

[0029] In the embodiments of the present application, the road traffic signal controller first receives the real-time route planning data sent by the handheld communication terminal through its wireless communication interface. These data may include the real-time position of the special vehicle, destination information and recommended travel path, etc.

[0030] After receiving the data, the second processing center will perform data verification to ensure the integrity and accuracy of the data. This includes checking whether the data format is correct, whether the signature is valid, etc. The second processing center will analyze the real-time route planning to determine the recommended travel path of the special vehicle. This includes parsing the route planning data and extracting key information such as road numbers, intersections, etc.

[0031] The road traffic signal controller is usually equipped with a signal machine database, which stores the position, number, control range, etc. of all signal machines within the control range of the controller. The second processing center matches the key information in the real-time route planning with the data in the signal machine database. This process compares the road numbers or intersections in the route planning with the control range of the signal machines in the database, thereby determining which signal machines are related to the travel path of the special vehicle.

[0032] Based on the matching results, the second processing center generates a relevant signal machine list. This list contains all signal machines that the special vehicle may encounter during its journey, as well as their positions and roles in route planning.

[0033] Step S400: Establish a first communication connection between the first signal machine and the handheld communication terminal, where the first signal machine is any one of the multiple signal machines;

[0034] In the embodiments of the present application, among the multiple signal machines, the first signal machine that establishes a communication connection with the handheld communication terminal is determined. This is usually based on real-time route planning, and the signal machine that the special vehicle will soon reach or has already reached is selected as the first signal machine.

[0035] Before establishing the communication connection, it is checked whether the power supply, communication interface, and control system of the signal machine are functioning normally, to ensure that the first signal machine is in a normal working state.

[0036] The handheld communication terminal and the signal machine need to follow the same communication protocol to ensure correct transmission and analysis of data. Standardized communication protocols such as TCP / IP, UDP, HTTP, etc. are usually used.

[0037] Step S500: The handheld communication terminal activates the first signal machine into a first temporary execution mode based on the first communication connection;

[0038] In the embodiments of the present application, the handheld communication terminal generates an activation instruction for the first signal machine according to real-time route planning and traffic conditions. This instruction includes specific parameters for entering the temporary execution mode, such as duration, etc. The activation instruction is encapsulated into a data packet that conforms to the communication protocol, to ensure that the instruction can be correctly transmitted and analyzed. Through the first communication connection that has been established, the handheld communication terminal sends the activation instruction to the first signal machine.

[0039] The first signal machine receives the activation instruction from the handheld communication terminal. The first signal machine will verify the received instruction, checking its legality, integrity, and accuracy. If the instruction passes the verification, it will start entering the first temporary execution mode.

[0040] Step S600: Invoke a predetermined temporary execution scheme in the urban traffic management platform;

[0041] In the embodiments of the present application, it is necessary to evaluate the current traffic conditions and specific needs to determine whether a predetermined temporary execution scheme needs to be invoked. According to the evaluation results, a suitable predetermined temporary execution scheme is selected from the urban traffic management platform. These schemes are pre-set for different traffic scenarios and needs, such as priority passage, traffic control, etc.

[0042] Step S700: The first signal machine optimizes the control of the first signal light in the first temporary execution mode in combination with the predetermined temporary execution scheme.

[0043] In the embodiments of the present application, when the first signal machine enters the first temporary execution mode, it will load data related to the predetermined temporary execution scheme in the urban traffic management platform. These data include signal light phase adjustment, green light duration change, priority setting, etc.

[0044] The first signal machine will analyze the loaded temporary execution scheme and extract specific control instructions for the first signal light. These instructions involve changing the light-on sequence of the signal light, adjusting the light-on duration, or implementing priority passage for specific traffic flow, etc.

[0045] In the first temporary execution mode, the first signal machine continuously monitors the state of the first signal light and real-time traffic data, including the current phase of the signal light, the light-on duration, traffic flow, vehicle queuing situation, etc. By analyzing the collected data, the first signal machine evaluates the current traffic conditions and the working effect of the signal light, providing a basis for subsequent optimization control.

[0046] According to the real-time data analysis and the predetermined temporary execution scheme, the first signal machine dynamically adjusts the control strategy of the first signal light by adjusting the phase sequence of the signal light, extending or shortening the light-on duration of specific phases, providing priority passage for specific traffic flow, etc. When adjusting the control strategy, the first signal machine applies some optimization algorithms, such as adaptive control algorithm, fuzzy control algorithm, etc., to improve the control effect and response speed of the signal light.

[0047] According to the optimized control strategy, the first signal machine will generate specific control instructions for adjusting the working state of the first signal light. The first signal machine will send the generated control instructions to the first signal light, so that it works according to the instructions.

[0049] The special vehicles include but are not limited to fire vehicles, emergency vehicles, special service vehicles, public transport vehicles, police vehicles, and military vehicles.

[0050] In the embodiments of the present application, in the intelligent traffic control system, special vehicles generally refer to vehicles that need priority passage or special treatment when performing tasks. These vehicles include but are not limited to fire vehicles, emergency vehicles, special service vehicles, public transport vehicles, police vehicles, and military vehicles.

[0052] The form of the handheld terminal includes but is not limited to mobile phones, tablets, portable laptops, and vehicle display terminals.

[0053] In the application embodiment, the handheld terminal is a portable data processing device with various forms, not limited to specific device types. In addition to the common forms of mobile phones, tablets, portable laptops, and vehicle display terminals, the handheld terminal also includes other forms, such as smartwatches, smartbands, and other wearable devices. These devices have different characteristics and functions and can meet the needs of different users.

[0056] In the application embodiment, the handheld terminal is a device with rich functions, which has various practical functions.

Whether it is positioning, mapping, remote communication, or rechargeable battery power supply, DC / AC power supply, touch input, key input, voice prompt, and screen display, it provides users with convenient and efficient use experience.

[0057] Further, the step S400 in the method provided by the application embodiment further includes:

[0058] The first communication connection is a wireless communication connection, including but not limited to 4G communication, 5G communication, NB-IoT communication, WIFI communication, Lora communication, and Bluetooth communication.

[0059] In the application embodiment, the first communication connection serves as a communication bridge between the handheld terminal and external networks or other devices, covering various wireless communication technologies. These technologies each have their own characteristics and are suitable for different application scenarios and needs, providing users with flexible and diverse communication methods. Whether it is high-speed 4G / 5G communication, low-power NB-IoT / LoRa communication, or widely used WIFI and Bluetooth communication, the handheld terminal has strong functions and flexibility in communication connection.

[0060] Further, the method further includes:

[0061] analyzing the real-time route planning to obtain a first passage time period, the first passage time period being a time period for the special vehicle to pass the first signal light;

[0062] determining whether the first passage time period meets a predetermined time period threshold;

[0063] if yes, monitoring the intersection where the first signal light is located through a first intersection monitoring device in the first signal machine to obtain first intersection vehicle state information;

[0064] analyzing the first intersection vehicle state information to obtain a first intersection vehicle congestion index, and determining whether the first intersection vehicle congestion index is within a predetermined congestion index threshold;

[0065] if yes, optimizing control of the first signal light in combination with a predetermined peak temporary implementation scheme in the predetermined temporary implementation scheme.

[0066] In the embodiments of the present application, real-time route planning is usually based on multiple data sources such as geographic information systems, traffic flow data, road condition information, etc. The system will calculate one or more recommended driving paths according to the current position, destination of the special vehicle, and the road and traffic conditions along the way. In real-time route planning, the first passage time period refers to the time period for the special vehicle to pass the first signal light. This time period is calculated based on the current speed, expected driving speed, road conditions, and signal light working cycle of the special vehicle. The specific calculation method of determining the first passage time period may vary depending on different route planning systems and algorithms. However, generally, the system will use certain algorithms such as shortest time algorithm, least turn algorithm, etc. to predict the time for the special vehicle to reach each signal light based on the above factors, and determine the first passage time period accordingly.

[0067] The predetermined time period threshold is a time range preset in the traffic management system for evaluating whether the time for the special vehicle to pass the signal light is reasonable. This threshold is usually determined based on traffic flow, road conditions, signal light working cycle, etc. to ensure that the special vehicle can pass the intersection smoothly without affecting other traffic participants. Once the real-time route planning system calculates the first passage time period, i.e. the time period for the special vehicle to pass the first signal light, the system compares this time period with the predetermined time period threshold to determine whether the special vehicle can pass the signal light within a reasonable time.

[0068] The determination process is to compare the start time and end time of the first passage time period with the start time and end time of the predetermined time period threshold to check whether they coincide or intersect. The start time and end time of the first passage time period are compared with the start time and end time of the predetermined time period threshold to check whether they coincide or intersect.

[0069] If the first passing period meets the predetermined period threshold, the system further monitors the intersection where the first signal light is located through a first intersection monitoring device in the first signal machine. These monitoring devices include cameras, sensors, etc., for obtaining vehicle state information of the intersection, such as the number of vehicles, speed, direction of travel, etc.

[0070] According to the obtained first intersection vehicle state information, the system analyzes and calculates the vehicle congestion index of the intersection. This index is a quantitative value for indicating the degree of traffic congestion at the intersection. The system determines whether the congestion index is within a predetermined congestion index threshold.

[0071] When it is determined that the vehicle congestion index of the first intersection is within the predetermined congestion index threshold, it means that the traffic condition at the intersection has been relatively congested, and additional measures need to be taken to alleviate the traffic pressure. In this case, the system combines the predetermined peak temporary implementation scheme in the predetermined temporary implementation scheme to optimize the control of the first signal light.

[0072] The predetermined peak temporary implementation scheme is a set of strategies pre-established in the traffic management system to deal with peak periods or congestion situations. This scheme usually includes a series of signal light optimization measures aimed at improving the efficiency of the intersection and reducing traffic congestion. When the vehicle congestion index of the first intersection is within the predetermined threshold, the system triggers the predetermined peak temporary implementation scheme to optimize the control of the first signal light. The specific measures of optimization control include setting the signal light of the passing direction of the special vehicle to green and the signal lights of other directions at the intersection to red, trying to release the queued vehicles at the intersection.

[0073] Further, the determination of whether the first passing period meets the predetermined period threshold further includes:

[0074] If not, the first signal light is optimized and controlled in combination with the predetermined flat peak temporary implementation scheme in the predetermined temporary implementation scheme.

[0075] In the embodiments of the present application, when the first passing period does not meet the predetermined period threshold, the time for the special vehicle to pass the first signal light is not within the ideal range. In this case, the system combines the predetermined flat peak temporary implementation scheme in the predetermined temporary implementation scheme to optimize and control the first signal light. For example, when the signal machine detects that the distance from the special vehicle is greater than 1 km, the signal machine control prolongs the green light time of the direction in front of the special vehicle, increases the single cycle green light time by 30 seconds, the signal light scheme of other directions in the cycle remains unchanged, releases the vehicles queuing at the intersection, and the signal lights of other directions normally operate to ensure the normal passage of other vehicles at the intersection. When the signal machine detects that the distance from the special vehicle is less than 1 km, the signal machine control sets the running direction of the special vehicle to green and the other directions at the intersection to red, waiting for the special vehicle to pass. After the special vehicle passes, the signal machine restores the normal operation scheme.

[0076] The predetermined flat peak temporary execution scheme is a set of strategies formulated in the traffic management system for flat peak periods or situations with low traffic flow. The purpose of this scheme is to improve the efficiency and smoothness of traffic flow by optimizing signal light control when traffic flow is relatively low. When the first passing period does not meet the predetermined period threshold, the system triggers the predetermined flat peak temporary execution scheme to optimize the control of the first signal light. The measures of optimization control include extending the green light duration and adjusting the signal timing.

[0077] Further, after judging whether the first intersection vehicle congestion index is within the predetermined congestion index threshold, the method further comprises:

[0078] If not, the first signal machine sends a first instruction to the handheld communication terminal, and the first instruction is used to prompt the special vehicle for intersection congestion and needs to change the route.

[0079] In the embodiment of the application, the vehicle congestion index of the first intersection is not within the predetermined congestion index threshold range, which means that the first intersection is in peak congestion, and the intersection condition cannot be regulated. At this time, the first signal machine sends a first instruction to the handheld communication terminal to prompt the special vehicle for intersection congestion, informs the intersection congestion, and gives a new route to prompt the special vehicle to change the route.

[0080] In summary, the embodiment of the application has at least the following technical effects:

[0081] The application obtains the destination; the handheld communication terminal sends the real-time route planning to the road traffic signal control machine; the second processing center in the road traffic signal control machine matches the multiple signal machines in the real-time route planning; a first communication connection between the first signal machine and the handheld communication terminal is established; the communication terminal activates the first signal machine to enter a first temporary execution mode based on the first communication connection; a predetermined temporary execution scheme in the traffic management platform is called; and the first signal machine optimizes the control of the first signal light in the first temporary execution mode in combination with the predetermined temporary execution scheme. The application solves the technical problem that the special vehicle encounters traffic congestion and has a collision risk when breaking the red light in the prior art, and achieves the technical effects of reducing the collision accident risk of the special vehicle and providing the route with the shortest passing time.
