It is particularly crucial in financial and business environments, where these systems ensure the accuracy, transparency, and efficiency of transactions. Technologies in this field include automated settlement systems, electronic payment gateways, blockchain technology, and various security mechanisms for handling transactions ranging from simple retail transactions to complex cross-border financial transactions. Additionally, this technical field is constantly adapting to new market demands, such as contactless payments and cryptocurrency transactions, all aimed at increasing processing speed and reducing costs.
[0003] Among them, an automated highway toll management system refers to the use of electronic technology to automatically process the fees generated by vehicles during highway use.

The optimized charging strategy specifically includes charging differentiation, key node pricing, and multi-path pricing. The updated toll standard notice includes toll rate setting, passing rate synchronization, and rate change record. The traffic flow dynamic results include traffic flow density change and vehicle route selection ratio.
[0082] Please refer to Figure 2 , and the steps for obtaining the driving trajectory are specifically as follows:
[0083] Based on the global positioning system, the geographical location coordinates of the vehicle are collected in real time. The vehicle sends the position coordinate data to the data center every second to obtain the real-time geographical location coordinate data;
[0084] Based on the geographical location coordinates collected in real time by the global positioning system, the vehicle uploads its current position coordinates to the data center every second. Through the real-time data, the position and movement path of the vehicle can be traced. By marking the timestamp of each data point, the data points can be organized into a time series. Such an organization method not only ensures the continuity of the data but also helps with subsequent position data processing and analysis. When performing route optimization and traffic flow analysis, time-series data can provide more information and insights. For example, by analyzing the moving speed and staying time of vehicles, the scheduling of traffic signals can be optimized to reduce traffic congestion. The obtained real-time geographical location coordinate data provides a basis for subsequent analysis.
[0085] Perform time serialization processing on the real-time geographical location coordinate data, mark each data point with a timestamp, and organize the data in chronological order to generate time-serialized geographical location coordinate data;
[0086] After performing time serialization processing on real-time geographical location coordinate data, each data point is marked with a timestamp, and the data is arranged in chronological order. This method of organizing data can track the driving path of a vehicle. By connecting the data points, a driving trajectory map of the vehicle is formed. This map not only helps to monitor the current position of the vehicle but also enables the analysis of its driving efficiency and route selection. In addition, the time-serialized data can be used to predict traffic patterns and optimize routes. By comparing the data in different time periods, peak hours and traffic bottlenecks can be identified, and then the operation of traffic lights can be adjusted or the scheduling of public transportation can be optimized. The generated time-serialized geographical location coordinate data provides an estimate for building a more effective traffic management system.
[0087] Extract the position at each time point from the time-serialized geographical location coordinate data, and calculate the displacement between two adjacent time points using the formula:
[0088]
[0089] Generate a driving trajectory;
[0090] Among them, represents the abscissa of the geographical coordinates of the first time point, represents the ordinate of the geographical coordinates of the first time point, represents the abscissa of the geographical coordinates of the second time point, represents the ordinate of the geographical coordinates of the second time point, represents the straight-line distance between two adjacent time points.
[0091] Formula:
[0092]
[0093] The advantage of the formula is that by calculating the distance between two time points, the moving speed and driving state of the vehicle can be monitored in real time, which helps the traffic management center to respond to estimated traffic accidents or congestion situations.
[0094] Detailed explanation of the formula and the derivation process of the formula calculation:
[0095] Set that at time point t1, the vehicle is at the geographical location , and at time point t2, it is at . Calculate the distance between these two time points:
[0096]
[0097] The results show that the vehicle has moved approximately 42.43 meters between two time points. If the time interval is 1 second, the vehicle's speed can be calculated to monitor whether its driving condition is normal. The calculation results provide basic data for subsequent traffic behavior analysis and traffic flow prediction.
[0098] Please refer to Figure 3 , and the steps to obtain the real-time traffic map status are specifically as follows:
[0099] Through sensors and communication technologies, the vehicle collects the geographical locations and speed data of itself and surrounding vehicles, determines the relative motion states between vehicles including following or overtaking, and generates relative position and behavior data between vehicles;
[0100] Through the sensors and communication technologies installed in the vehicle, the positions and speed information of the vehicle and its surrounding vehicles are collected in real time. Based on these data, data processing and analysis methods are used to determine the relative motion states between vehicles, including following and overtaking behaviors. This process includes obtaining raw data from sensors, identifying vehicle behavior patterns through algorithms, and classifying and storing behavior data to provide input data for subsequent traffic map construction, generating relative position and behavior data between vehicles.
[0101] Using the relative position and behavior data between vehicles, the nodes and edges of the graph are constructed. Each vehicle serves as a node, and its relative motion behavior defines the direction and type of the edge, generating the basic structure of the graph;
[0102] Utilizing the vehicle behavior data obtained from sensors and combining with the real-time position information of the vehicle, the nodes and edges of the traffic flow map are constructed. Each vehicle represents a node, and its relative behavior with other vehicles including following or overtaking defines the direction and type of the edge. This process not only includes data collection and analysis but also the implementation of a graph construction algorithm based on vehicle behavior patterns to dynamically describe the traffic conditions on the road and generate the basic structure of the traffic map.
[0103] Based on the basic structure of the graph, the attributes of the nodes and edges are updated in real time, including vehicle speed and vehicle spacing, using the formula:
[0104]
[0105] Generate the real-time traffic map status;
[0106] Among them, represents the updated characteristics of the node or edge, represents the characteristics before update, represents the monitored change in characteristics, is used to control the degree of fusion between the previous data and the new data.
[0107] Formula:
[0108]
[0109] The advantage of the formula is that it provides a method for dynamically updating the features of traffic map nodes and edges, making the traffic state more real-time and accurate. By adjusting , the influence of previous data and newly observed data can be balanced, thus optimizing the prediction and management of traffic flow.
[0110] Detailed explanation of the formula and the derivation process of formula calculation:
[0111] Set that in one data update cycle, the original speed feature value of a vehicle is 30 km / h, and the observed speed change is 5 km / h. The smoothing factor is set to 0.2, representing the weight of new data. According to the formula, the current speed feature value is calculated as follows:
[0112]
[0113] The result shows that referring to the combination of previous data and newly observed data, the updated speed of the vehicle is 25 km / h, which helps to adjust the state of the vehicle in the traffic map in real time, thus providing more accurate traffic flow information.
[0114] Please refer to Figure 4 , and the specific steps for obtaining the node influence score are as follows:
[0115] Based on the real-time traffic map state, collect the feature data of multiple nodes, including vehicle speed, driving direction and position. By analyzing the features, generate a node feature matrix, and call the feature matrix for node feature extraction to generate node feature data;
[0116] Based on the real-time traffic map state, the collection of node feature data involves the real-time monitoring of vehicle speed, driving direction and position. The data is continuously captured by the sensors of the traffic monitoring system and transmitted to the data processing center in real time through the wireless network. The data processing center uses high-performance servers to analyze and process the collected data, uses data mining techniques to identify driving patterns and behavior anomalies. The feature matrix of each node consists of a speed vector, a direction angle and a position coordinate. The features are merged through a data fusion algorithm to ensure the integrity and accuracy of the information. The system dynamically adjusts and optimizes the traffic flow prediction model by comparing the previous data and the real-time data, and the generated node feature data is used for traffic management and control decision support.
[0117] Using the node feature data, extract the driving pattern. By calculating the feature fitting degree, use the formula:
[0118]
[0119] Generate the driving mode score of the node;
[0120] Among them, represents the driving mode score of the node , is the feature fitting degree between the node and the node , is the feature dimension of the node , is the time factor, is a constant to avoid a zero denominator;
[0121] Formula:
[0122]
[0123] Detailed explanation of the formula and the derivation process of the formula calculation:
[0124] This formula is used to evaluate the driving mode score of the vehicle , based on the fitting degree between other vehicles and the vehicle and the time factor . Standardization is achieved through the feature dimension and a decimal number to avoid division-by-zero errors.
[0125] : The feature fitting degree between vehicle and vehicle is obtained by calculating the cosine fitting degree of the feature vectors of the two vehicles. If the speed of vehicle is 60 km / h and the direction is north, while the speed of vehicle j is 62 km / h and the direction is also north, then is close to 1, indicating a high degree of similarity.
[0126] : The time factor reflects the proximity of the data time point of vehicle to the scoring calculation time, and is calculated from the reciprocal of the time difference. If the data is 1 hour from now, is 1, and if the data is 2 hours from now, is 0.5.
[0127] : The feature dimension of vehicle includes speed, direction, and behavior. If vehicle has three features, then .
[0128] : A small constant, 0.01, is used to ensure that the denominator is not zero.
[0129] There are two vehicles set = 1 and = 2 are compared with the vehicles to obtain the following parameter values:
[0130] (similar in height to vehicle 1)
[0131] (moderately similar to vehicle 2)
[0132] (data from 1 hour ago)
[0133] (data from 2 hours ago)
[0134] (vehicle has three characteristic dimensions)
[0135] (a small constant to avoid division by zero)
[0136] Formula calculation process:
[0137]
[0138] The results show that the driving pattern score of the vehicle is 0.424, which reflects the weighted fitness of other vehicles with the most similar characteristics in terms of time and behavior. This score helps to determine the behavior pattern of the vehicle in the traffic network and is the basis for iterative analysis of vehicle interactions and mobility.
[0139] According to the driving pattern scores of the nodes, calculate the mutual forces between vehicles using the formula:
[0140]
[0141] Generate data on the mutual forces between vehicles;
[0142] Among them, represents the influence factor, indicating the interaction influence between node and node ; represents the driving pattern score of node ; represents node and the distance between node reflecting the physical interval between the two nodes; is the proportionality coefficient of the mutual force, used to adjust the intensity of the mutual force;
[0143] Formula:
[0144]
[0145] Detailed Explanation of the Formula and Derivation Process of Formula Calculation:
[0146] This formula is used to calculate the between the vehicle and the vehicle The mutual force between them is a key indicator reflecting the degree of mutual influence of the behaviors between the two vehicles. The parameter definitions in the formula are as follows:
[0147] and : The driving mode scores of vehicle and vehicle These scores reflect the behavioral characteristics of the vehicles. The has been calculated in the previous steps. Set to 0.5.
[0148] : Influence factor, characterizing the and The strength of the interaction between them. If the two vehicles often drive on the same section of the road, the value is relatively high, set to 0.8.
[0149] : The actual distance between vehicle and is in meters. Set the distance between the two vehicles to 100 meters.
[0150] : Proportional coefficient, determined according to vehicle density and traffic flow, set to 0.05. This value is obtained based on real-time traffic conditions and data analysis.
[0151] Let the numbers in the formula calculation process be as follows: , , , , (meters)
[0152] Calculation process:
[0153]
[0154] The result shows that the mutual force between vehicle and vehicle is 0.000848. This value is relatively small, indicating that although the two vehicles are relatively similar and relatively close, due to high traffic mobility or similar vehicle speeds, the mutual force is not large.
[0155] Using the data of the interaction forces between vehicles, analyze the impact of the connectivity between nodes on the network structure, and generate node influence scores by calculating connectivity scores.
[0156] Analyze the connectivity between nodes using the data of the interaction forces between vehicles. This process involves comparing the actual monitored vehicle behaviors with the predictions in the traffic model, calculating the influence score of each node in the traffic network, which refers to the geographical location, speed of the vehicle, and the interaction forces of the surrounding vehicles. Calculate the connectivity of multiple nodes through a mathematical model, and iteratively analyze how these connectivities affect the fluidity and stability of the entire network. The model will output the influence scores of each node, and these scores assist the traffic management system in identifying key road sections and traffic congestion points, optimizing the allocation of traffic signals and route planning. The results are directly used to adjust traffic lights and issue traffic warnings to improve road usage efficiency and reduce congestion.
[0157] Please refer to Figure 5 , and the specific steps for obtaining the optimized toll strategy are as follows:
[0158] Based on the node influence scores, analyze the impact of vehicles on the traffic flow, identify the vehicles at key nodes, set a toll benchmark for the vehicles, and generate preliminary toll standard data;
[0159] By analyzing the vehicle influence scores, determine which vehicles belong to key nodes. Vehicles at key nodes usually have greater influence, and their impact on the traffic flow is particularly significant. Therefore, it is crucial to consider this factor when setting toll standards. By collecting influence data, set higher toll standards for vehicles with greater influence, which can more fairly allocate the road usage costs, and at the same time encourage drivers to choose more reasonable travel times and routes, thereby optimizing traffic fluidity and reducing congestion.
[0160] Using the preliminary toll standard data, calculate the difference in influence scores between adjacent vehicles, using the formula:
[0161]
[0162] Generate influence difference data;
[0163] Among them, and respectively represent the influence scores of adjacent vehicles, used to measure the influence of different vehicles in the traffic network, is a small positive number, used to ensure that the denominator is not zero when calculating the influence difference, represents the influence difference between adjacent vehicles, used to evaluate the gap in influence between two vehicles;
[0164] Formula:
[0165]
[0166] The benefit of the formula is that it quantifies the difference in influence between two vehicles, provides an actual numerical difference, which is convenient for adjusting the toll strategy and is crucial when referring to the fairness of the toll strategy and the effectiveness of traffic management.
[0167] Detailed explanation of the formula and the derivation process of the formula calculation:
[0168] Let , This represents the influence scores of two vehicles, where To ensure that the calculation can still proceed stably when the difference in influence scores is very small. The calculation process is as follows:
[0169]
[0170]
[0171]
[0172]
[0173]
[0173] The result shows that the difference in the influence scores of the two vehicles is 10.05. This difference will be used for subsequent adjustment of the toll standard, so as to ensure that the vehicle with greater influence bears more traffic costs. In this way, it encourages drivers to avoid peak hours or choose alternative routes, thus helping to relieve the traffic pressure on key roads.
[0174] According to the influence difference data and the criticality of the vehicle's driving path, dynamically adjust the toll standard, using the formula:
[0175]
[0176] Generate the adjusted toll strategy;
[0177] Among them, is the basic toll standard, reflecting the general toll standard when not referring to the target influence of individual vehicles, is the adjustment parameter, used to adjust the toll standard according to the influence difference between vehicles, represents the current toll standard;
[0178] Formula:
[0179]
[0180] The benefit of the formula is that by adding to the basic toll depending on the influence difference Adjustment items are used to flexibly adjust the charging strategy to match the actual influence of different vehicles, so as to more fairly allocate the road use cost, and use economic means to encourage drivers to optimize their driving routes and times, thereby reducing traffic congestion.

[0182] Set The basic charging standard per unit, obtained from the above results , set the adjustment coefficient , the calculation process is as follows:
[0183]
[0184]
[0185]
[0186]
[0187]
[0188] The results show that after referring to the influence difference between adjacent vehicles, the current charging standard should be adjusted to 50.52 units, which reflects the fair charging principle based on the actual influence of vehicles, and through this differential charging, it encourages drivers to choose driving times and routes with less impact on traffic flow, aiming to optimize traffic flow and reduce congestion.
[0189] Combined with the adjusted charging strategy, referring to the criticality of traffic flow in multi-path selection, an optimized charging strategy is generated.
[0190] Based on referring to the criticality of traffic flow on multiple driving routes, combined with the adjusted charging strategy, the overall charging strategy is iteratively optimized to ensure that the charging standard can dynamically reflect various driving conditions and traffic loads. This optimization refers to multiple variables, including the driving route of the vehicle, traffic density, and time period. By comprehensively considering these factors through an algorithm model, the generated optimized charging strategy aims to regulate traffic flow through economic means to make it smoother, reduce traffic congestion during peak hours, and the optimized strategy supports its effectiveness through real-time traffic data, so as to achieve the optimal charging effect in different traffic situations, improve the use efficiency of road resources, and implementing this strategy can significantly improve the adaptability and predictability of traffic management, making the traffic system more efficient and sustainable.
[0191] Please refer to Figure 6 , the specific steps to obtain the updated charging standard notice are as follows:
[0192] Based on the optimized charging strategy, update the toll station parameters, collect the rate values of the current toll collection equipment, compare the difference between the current rate and the current adjustment standard, and generate the rate value result of the current toll collection equipment;
[0193] When updating the toll station parameters, first collect the current rate values of the equipment. The data collection work is completed by accessing the management system of each toll station. The system records the settings and adjustment records of multiple devices. By comparing the data with the current standards of the policy orientation, it is determined which devices need to adjust the rate values to comply with the current toll collection policy. This comparison process involves data extraction, analysis, and comparison, ensuring the accuracy and timeliness of the rate adjustment and generating the rate value result of the current toll collection equipment.
[0194] Using the rate value result of the current toll collection equipment, calculate the updated rate using the formula:
[0195]
[0196] Generate the updated rate result;
[0197] Where, represents the updated rate, represents the base rate, represents the current rate, represents the adjustment coefficient, represents the additional factor coefficient;
[0198] Formula:
[0199]
[0200] The advantage of the formula is that by introducing the adjustment coefficient and the additional factor coefficient , the rate is dynamically adjusted based on market and policy changes, improving the adaptability and flexibility of the toll collection model.
[0201] Detailed explanation of the formula and the derivation process of the formula calculation:
[0202] Assume (base rate, set to 1 yuan per kilometer of passage), (current rate, already increased by 20%), (adjustment coefficient, indicating an adjustment range of 50% of the difference between the base rate and the current rate), (additional factor coefficient, indicating an additional increase of 5%).
[0203] The calculation process is as follows:
[0204] 1. Calculate the differential adjustment:
[0205] 2. Apply adjustment factors:
[0206] 3. Calculate the new base rate:
[0207] 4. Apply additional factor coefficients:
[0208] The updated rate Yuan.
[0209] The results show that, with reference to the current market conditions and policy requirements, the current prevailing rate is adjusted to 1.155 yuan per kilometer, ensuring the fairness of the rate and the consistency of the policy.
[0210] Combined with the updated rate results, set the prevailing rate information of the vehicle-end system, perform information synchronization and verification operations, and generate the vehicle-end system prevailing rate information results;
[0211] When setting the prevailing rate information of the vehicle-end system, the operator needs to extract the associated values from the updated rate data, input the values through vehicle management, perform format verification and logical checks on these data to avoid data errors or inconsistencies, and ensure that the current rate can be accurately synchronized to each passing vehicle. Including data upload, processing, and distribution, the operator needs to monitor the data transmission process and promptly handle any synchronization errors that occur, generate the vehicle-end system prevailing rate information results, and the data will be used to calculate the actual passing fees of the vehicle.
[0212] According to the vehicle-end system prevailing rate information results, issue a notice on the update of vehicle passing fees, record the toll rate change log at the toll station, and generate an updated toll standard notice.
[0213] Issuing a notice on the update of vehicle passing fees and recording the toll rate change log at the toll station involve extracting the current rate from the vehicle-end system prevailing rate information and publishing the change information to the public and related departments through the network broadcast system. At the same time, the operator needs to update the log in the internal management system, record the details of each toll rate change, including the change time, the equipment involved, the toll rates before and after the change, as well as the reasons and expected impacts of the change. These records are crucial for subsequent data review, policy evaluation, and compliance checks, ensuring the transparency and traceability of the toll policy and generating an updated toll standard notice.
[0214] Please refer to Figure 7 , the specific steps for obtaining the traffic flow dynamic results are as follows:
[0215] Based on the updated toll standard notice, monitor the real-time impact of toll changes on vehicle passing route selection, record the changes in route selection, and generate vehicle route selection data;
[0216] Based on the updated toll standard notice, record the changes in vehicle route selections on key sections. Capture data through the real-time traffic monitoring system, use GPS tracking technology to determine the actual driving routes of vehicles, and compare with the data before the notice was issued. Analyze the preference differences in vehicle travel routes before and after the toll change, and display the sensitivity of vehicles to the differential toll sections in the form of charts and percentages. This real-time monitoring not only assists urban traffic management departments in evaluating the actual impact of toll strategies but also provides data support for adjusting future toll policies.
[0217] Utilize vehicle route selection data to record the real-time driving trajectories of vehicles, analyze the data, and monitor the vehicle flow trends on key sections to generate real-time driving trajectory results;
[0218] Based on vehicle route selection data, implement a trajectory recording program. Cameras and sensors deployed at multiple key traffic nodes collect vehicle passing data, use big data analysis technology to process the collected information, identify frequently occurring routes and traffic congestion points through algorithm models, and the analysis model will predict traffic flow changes based on time series, thereby providing a scientific basis for traffic dispatching and effectively predicting and managing urban traffic flow.
[0219] Extract data from the real-time driving trajectory results, analyze the redistribution process of traffic flow, and use the formula:
[0220]
[0221] Calculate and generate traffic flow redistribution indicators;
[0222] Among them, represents the traffic volume of the th route, indicating the number of vehicles passing through the route, represents the distance of the th route, indicating the length of this route, represents the total traffic volume of all routes during the monitoring period, used to normalize the route data, represents the redistribution indicator, used to measure the utilization rate and mobility of multiple routes in the overall traffic flow;
[0223] Formula:
[0224]
[0225] The benefit of the formula is that it provides an indicator to quantify the traffic flow redistribution and can calculate the impact of traffic flow changes on route selection,
[0226] Detailed explanation of the formula and the derivation process of formula calculation:
[0227] Set that there are three route branches on a key road, and the traffic volumes are respectively , , , the corresponding path distances are respectively , , , and the total traffic flow , and the calculation process is as follows:
[0228]
[0229] The results show that on average each vehicle travels nearly 2 kilometers, which reflects that after the toll change, vehicles tend to choose shorter routes to reduce costs.
[0230] Combined with the traffic flow redistribution index, quantify the change in traffic flow density and calculate the selection ratio of multiple paths, and use the dynamic analysis method to evaluate the change trend of path selection to generate the traffic flow dynamic results.
[0231] Use the dynamic analysis method to evaluate the change trend of path selection, record the selection of each vehicle and the corresponding time points, input the data into the computer simulation program for processing, simulate the traffic flow distribution under different scenarios by setting different traffic volume and time parameters, calculate the routes preferentially selected by vehicles under different toll standards, and form a report, which includes the impact of various toll changes on traffic flow density and path selection ratio, providing data for urban traffic planning and toll policy adjustment.
