A comprehensive judgment method for toll vehicle types on expressways

Abstract

The present invention discloses a comprehensive judgment method for toll vehicle types on expressways. Axle types and vehicle type information of vehicles are collected on-site at the lane, and historical reliable vehicle types of the vehicles are analyzed using historical passing big data. By combining historical big data and on-site judgment, the limitations of the vehicle type determination scheme based on historical big data are effectively solved. At the same time, a vehicle type verification scheme for the toll station exit lane system is designed, so that even if the vehicle type is misjudged at the entrance, the vehicle can still be corrected through verification at the exit, thereby ensuring the accuracy of the final vehicle toll calculation. The present invention enables the automatic discrimination and verification of vehicle types in both the entrance and exit lane systems of the toll station, thereby enabling the toll station lanes to be unattended, reducing the number of toll collectors, and lowering the work intensity of toll collectors.

Description

Technical Field

[0001] The present invention relates to the technical field of highway toll vehicle type judgment, and in particular to a comprehensive judgment method for highway toll vehicle types. Background Art

[0002] Driven by the project of canceling provincial boundary toll stations on highways, ETC vehicles have been vigorously popularized and the number has increased significantly. The number of ETC dedicated lanes at toll stations has also increased accordingly. However, there are still non-ETC vehicles and some ETC trucks that need to pass through mixed lanes. At the same time, since the vehicle type is directly related to the accuracy of vehicle toll billing, it is necessary to manually confirm or input the accurate vehicle type at the entrance of the toll station. Even for a towed truck equipped with an ETC device, it is necessary to confirm the vehicle type and the number of axles at the entrance of the toll station before passing. Some areas of highways are also piloting vehicle type automatic identification schemes, but mainly rely on single data sources such as video vehicle type identifiers based on machine vision or historical passing big data analysis to judge vehicle types, and do not adopt a multi-data source verification scheme.

[0003] Before canceling the provincial boundary toll stations, automatic card issuing devices have been widely popularized at the entrances of highways across the country. Under the new toll model after canceling the provincial boundary toll stations, it is necessary to confirm or input the accurate vehicle type when the vehicle enters the highway. Therefore, it is necessary to increase card issuing personnel in the entrance lane, which increases the toll labor cost, increases the work pressure of toll collectors, and often misjudges vehicle types due to work fatigue, resulting in billing errors. Especially for trucks with floating axles, it is more difficult to judge the vehicle type.

[0004] Judging vehicle types solely relying on machine vision technology, its overall accuracy rate is not higher than 97% after statistics. Especially for the vehicle type determination accuracy rates of passenger cars, type 1 trucks, type 2 trucks, and special operation vehicles are lower than 95%. Applying it on highways with large traffic flow will cause a large number of vehicle type misjudgments, thus affecting the billing accuracy. Although the historical passing big data samples are all historical manually judged data, it not only lacks sample data for vehicles that enter the highway for the first time or rarely, but also for towed trucks, due to the non-fixed axle types and vehicle types for each passing, its historical data also has no reference value. Summary of the Invention

[0005] The purpose of the present invention is to provide a comprehensive judgment method for highway toll vehicle types, comprehensively using multiple-dimensional data sources, formulating a set of intelligent vehicle type discrimination methods with high accuracy according to different vehicle type characteristics and data source credibility, which can realize the automatic discrimination of vehicle types by the lane toll system, effectively improve the accuracy rate of highway toll vehicle type judgment, reduce the frequency of toll collector intervention, and improve the vehicle passing efficiency of toll stations.

[0006] The technical solution adopted by the present invention is:

[0007] A comprehensive judgment method for toll vehicle types on expressways, which is applied to the stage when a vehicle enters and exits the entrance and exit lanes of an expressway toll station. The method includes the following steps:

[0008] S1. When the vehicle enters and exits the expressway toll station lane, obtain the weighing axle type, license plate number, machine axle type, and machine vehicle type respectively;

[0009] S2. Access the historical traffic big data cloud platform through the license plate number to analyze the historical vehicle type;

[0010] S3. Use the machine vehicle type and the historical vehicle type to comprehensively judge the toll vehicle type according to the characteristics of various vehicle types; if the judgment is successful, execute S4; otherwise, execute S5;

[0011] S4. According to the judged toll vehicle type, weighing axle type, and machine axle type, perform multi-source axle type data verification of the vehicle according to certain rules; when the verification is consistent, execute S6; when the verification is inconsistent, execute S5;

[0012] S5. The lane toll system notifies the on-duty toll collector that manual judgment of the vehicle type or axle type is required, and the toll collector confirms the toll vehicle type and axle type of the vehicle remotely.

[0013] S6. The lane toll system performs read and write operations on the expressway toll medium based on the toll vehicle type and then raises the barrier to release the vehicle.

[0014] Furthermore, in S1, the weighing axle type is obtained through the lane weighing equipment, the machine axle type and machine vehicle type are obtained through the video vehicle type identifier, and the license plate number is obtained through the license plate identifier.

[0015] Furthermore, when the vehicle is in the high-speed entrance lane stage, in S3, according to the obtained machine vehicle type and historical vehicle type, comprehensively judge the toll vehicle type respectively according to the characteristics of various vehicle types; the specific steps of S3 are as follows:

[0016] S301. Judge whether there is historical vehicle type data for the current vehicle and whether the proportion of a certain vehicle type in the historical vehicle type data is greater than the set threshold; if so, judge that the vehicle type corresponding to the corresponding category in the historical vehicle type data is credible vehicle type data, select the vehicle type corresponding to the corresponding category as the historical vehicle type and execute S302; otherwise, execute S303;

[0017] S302. Judge whether the historical vehicle type is a passenger car, a type 1 truck, a type 2 truck, or a special operation vehicle; if so, directly use the historical vehicle type as the toll vehicle type and execute S4; otherwise, that is, when the historical vehicle type is a type 3 truck, a type 4 truck, a type 5 truck, or a type 6 truck, execute S303;

[0018] S303. Judge whether the machine vehicle type has been obtained; if so, execute S4; otherwise, execute S5.

[0019] Furthermore, when the vehicle enters the entrance lane of the highway toll station, in S4, the multi-source axle type data of the vehicle is verified according to certain standards. The detailed steps are as follows:

[0020] S401, discuss according to the toll vehicle type finally determined in S3; when the toll vehicle type is a passenger car, directly use the weighed axle type; when the toll vehicle type is a truck or a special operation vehicle, go to S402;

[0021] S402, when the machine axle type is obtained and the machine axle type is the same as the weighed axle type, use the machine axle type; when the machine axle type is not obtained or the machine axle type is inconsistent with the weighed axle type, go to S5.

[0022] Furthermore, when the vehicle is in the entrance lane of the highway toll station, in S6, the lane writes the toll vehicle type and axle type into the highway passing medium, raises the barrier and releases the vehicle to enter the highway.

[0023] Furthermore, when the vehicle is in the exit lane stage of the highway toll station, in S1, further obtain the entrance axle type and entrance vehicle type by reading the vehicle passing medium.

[0024] Furthermore, when the vehicle is in the exit lane stage of the highway toll station, in S3, according to the obtained entrance vehicle type, machine vehicle type and historical vehicle type, comprehensively judge the toll vehicle type and charging method respectively according to the characteristics of various vehicle types; the detailed steps are as follows:

[0025] S301, when there is historical vehicle type data for the current vehicle and the proportion of a certain vehicle type in the historical vehicle type data is greater than the set threshold, determine that the vehicle type corresponding to the type in the historical vehicle type data is credible vehicle type data, select the corresponding type of vehicle as the historical vehicle type and execute S302; otherwise, execute S304;

[0026] S302, when the historical vehicle type is a passenger car, a Class 1 truck, a Class 2 truck or a special operation vehicle, execute S303; when the historical vehicle type is a Class 3 truck, a Class 4 truck, a Class 5 truck, a Class 6 truck, execute S304;

[0027] S303, judge whether the historical vehicle type is the same as the entrance vehicle type; if so, use the historical vehicle type as the toll vehicle type and use the charging amount in the card as the final toll amount; otherwise, use the historical vehicle type as the toll vehicle type and use the remote charging amount as the final toll amount.

[0028] S304, when there is a machine vehicle type and the machine vehicle type is the same as the entrance vehicle type, use the machine vehicle type as the toll vehicle type and use the charging amount in the card as the final toll amount;

[0029] When the vehicle type of the machine is inconsistent with the vehicle type at the entrance, but the axle type of the machine is consistent with the weighed axle type, use the vehicle type of the machine as the toll vehicle type and the remote billing amount as the final toll amount;

[0030] When the vehicle type of the machine is inconsistent with the vehicle type at the entrance and the axle type of the machine is also inconsistent with the weighed axle type, then execute S305;

[0031] S305. The toll booth operator confirms the manual vehicle type and determines whether the vehicle type at the entrance is consistent with the manual vehicle type. If so, use the manual vehicle type as the toll vehicle type and the billing amount in the card as the final toll amount; otherwise, use the manual vehicle type as the toll vehicle type and the remote billing amount as the final toll amount.

[0032] Furthermore, when the vehicle is at the exit lane of the highway toll station, in S4, the exit axle type is checked according to the weighed axle type and the machine axle type according to certain rules. The detailed steps are as follows:

[0033] S401. When there is a machine axle type, enter S402;

[0034] When there is no machine axle type, determine whether the weighed axle type is consistent with the entrance axle type. If so, enter S6; otherwise, enter S5;

[0035] S402. Determine whether the machine axle type is consistent with the weighed axle type and the entrance axle type. If so, enter S6; otherwise, enter S5.

[0036] Furthermore, when the vehicle is at the exit lane of the highway toll station, in S6, the lane calculates the final toll amount according to the toll vehicle type, collects the toll, clears or retrieves the highway toll media, and then raises the barrier to release the vehicle to leave the highway.

[0037] The present invention adopts the above technical solutions and has the following technical advantages: 1. Currently, the devices for collecting vehicle axle type and vehicle type information at the lane site are mainly weighbridges and video vehicle type identifiers. Among them, the weighbridge can only distinguish the vehicle axle type with an accuracy rate of about 95%; the video vehicle type identifier can distinguish the vehicle axle type and vehicle type with an accuracy rate of about 95% - 97%. The accuracy rates of both are not sufficient to be used as the basis for independently determining the vehicle type. However, the present invention compares and analyzes the data of the two, reducing the possibility of misjudgment on-site. 2. Using historical passing big data to analyze the historical reliable vehicle type of vehicles is only applicable to non-tractor trucks that often use the highway. The present invention effectively solves the limitation of the vehicle type determination scheme based on historical big data through a combination of historical big data and on-site judgment. 3. The present invention also designs a vehicle type verification scheme for the toll station exit lane system, so that even if the vehicle type is misjudged at the entrance, the vehicle can still be corrected through verification at the exit, thus ensuring the accuracy of the final vehicle toll calculation. 4. The present invention enables the toll station entrance and exit lane systems to automatically distinguish and verify the vehicle type, so that the toll station lanes can be unattended, reducing the number of toll collectors and the working intensity of toll collectors.

The explanations of relevant terms are as follows: The vehicle axle type returned by the weighing equipment in the lane of the highway toll station (hereinafter referred to as the weighing axle type). The vehicle type and axle type identified by the video vehicle type identifier in the lane of the highway toll station (hereinafter referred to as the machine axle type and machine vehicle type). The historical vehicle type data of vehicles analyzed by the historical traffic big data cloud platform with a credibility reaching above the threshold (hereinafter referred to as the historical vehicle type). The vehicle type determined by the remote operation of the toll collector (hereinafter referred to as the manual vehicle type). The vehicle type and axle type written into the passing medium at the highway entrance (hereinafter referred to as the entrance axle type and entrance vehicle type). The toll amount accumulated and written into the passing medium (CPC card or OBU device) by the ETC gantry system along the way during the vehicle's passage on the highway is called the toll amount charged in the card data. Due to the inconsistency of the vehicle types or axle types at the entrance and exit of the vehicle, the toll amount of the vehicle recalculated by the lane system remotely invoking the path fitting system is called the remote toll amount.

[0074] The following is a detailed description of the specific principle of the present invention:

[0075] When the vehicle is in the entrance lane stage of the highway toll station, for the comprehensive judgment method of the highway entrance toll model, the judgment mainly depends on four data sources, including historical model, machine model, machine axle type, and weighing axle type; the specific steps are as follows:

[0076] S1, The vehicle drives into the highway entrance lane, and the weighing axle type is obtained through the lane weighing equipment.

[0077] S2, The vehicle drives into the highway entrance lane, and the machine axle type and machine model are obtained through the video model identifier.

[0078] S3, The vehicle drives into the highway entrance lane, and the historical model is obtained by accessing the historical passing big data cloud platform through the license plate number recognized by the lane.

[0079] S4, According to the obtained machine model and historical model, the toll model is comprehensively judged respectively according to the characteristics of various models. Those for which the model can be judged enter S5; those for which the model cannot be judged enter S6. One of the current flowcharts for judging the model at the entrance is shown in Figure 1 , The detailed steps of S4 are as follows:

[0080] S401, If the vehicle has historical model data, and the proportion of a certain model in the historical model data is greater than a certain threshold (for example, 80%), then regard this model as credible model data, select this model as the historical model and enter S402, otherwise enter S403.

[0081] S402, If the historical model is a passenger car, a type 1 truck, a type 2 truck, or a special operation vehicle, directly use this historical model as the toll model and enter S5. If the historical model is a type 3 truck, a type 4 truck, a type 5 truck, or a type 6 truck (mainly a towed truck), enter S403.

[0082] S403, If the machine model is obtained, enter S5, otherwise enter S6.

[0083] S5, According to the judged toll model, weighing axle type, and machine axle type, the multi-source axle type data of the vehicle is checked according to certain rules. Those that pass the check enter S7; those that do not pass the check enter S6. One of the current flowcharts for checking the axle type at the entrance is shown in Figure 2 , The detailed steps of S5 are as follows:

[0084] S501. Discuss in different cases according to the final toll vehicle type in S4. If the toll vehicle type is a passenger car, directly use the weighed axle type. If the toll vehicle type is a truck or a special operation vehicle, go to S502.

[0085] S502. If the machine axle type is obtained and the machine axle type is the same as the weighed axle type, use the machine axle type. If the machine axle type is not obtained or the machine axle type is not the same as the weighed axle type, go to S6.

[0086] S6. The lane notifies the toll collector on duty that manual judgment of the vehicle type or axle type is required, and the toll collector confirms the toll vehicle type and axle type of the vehicle remotely.

[0087] S7. The lane writes the toll vehicle type into the highway toll medium (CPC card or OBU device), raises the barrier and releases the vehicle to enter the highway.

[0088] When the vehicle is at the exit lane stage of the highway toll station, for the comprehensive judgment method of the highway exit toll vehicle type and the selection method of the charging method, the judgment mainly relies on six data sources, including the entrance vehicle type, the entrance axle type, the weighed axle type, the machine vehicle type, the machine axle type, and the historical vehicle type. The specific steps for the comprehensive judgment of the highway exit vehicle type and the selection of the charging method are as follows:

[0089] T1. The vehicle enters the highway exit lane, and the weighed axle type is obtained through the lane weighing equipment.

[0090] T2. The vehicle enters the highway exit lane, and the machine axle type and the machine vehicle type are obtained through the video vehicle type identifier.

[0091] T3. The vehicle enters the highway exit lane, and the historical vehicle type is obtained by accessing the historical traffic big data cloud platform through the license plate number recognized by the lane.

[0092] T4. The vehicle enters the highway exit lane, and the lane reads the vehicle toll medium (CPC card or OBU device) to obtain the entrance axle type and the entrance vehicle type.

[0093] T5. According to the obtained entrance vehicle type, machine vehicle type and historical vehicle type, comprehensively judge the toll vehicle type respectively according to the characteristics of various vehicle types. Those for which the vehicle type can be judged enter T6; those for which the vehicle type cannot be judged enter T7. One of the current flowcharts for judging the vehicle type at the exit is shown in Figure 3 , and the detailed steps of T5 are as follows:

[0094] T501. If the vehicle has historical vehicle type data and the proportion of a certain vehicle type in the historical vehicle type data is greater than a certain threshold (for example, 80%), then regard this vehicle type as credible vehicle type data, select this vehicle type as the historical vehicle type and enter T502, otherwise enter T504.

[0095] T502: If the historical vehicle type is a bus, a Class 1 truck, a Class 2 truck, or a special operation vehicle, proceed to T503. If the historical vehicle type is a Class 3 truck, a Class 4 truck, a Class 5 truck, or a Class 6 truck, proceed to T504.

[0096] T503: Determine whether the historical vehicle type is the same as the entrance vehicle type. If they are the same, use the historical vehicle type as the toll vehicle type and the billing amount in the card as the final toll amount. Otherwise, use the historical vehicle type as the toll vehicle type and the remote billing amount as the final toll amount.

[0097] T504: If there is a machine vehicle type and it is the same as the entrance vehicle type, use the machine vehicle type as the toll vehicle type and the billing amount in the card as the final toll amount; if the machine vehicle type is different from the entrance vehicle type but the machine axle type is the same as the weighing axle type, use the machine vehicle type as the toll vehicle type and the remote billing amount as the final toll amount; if the machine vehicle type is different from the entrance vehicle type and the machine axle type is also different from the weighing axle type, proceed to T505.

[0098] T505: Obtain the manual vehicle type through T7. If the entrance vehicle type is the same as the manual vehicle type, use the manual vehicle type as the toll vehicle type and the billing amount in the card as the final toll amount. If the entrance vehicle type is different from the manual vehicle type, use the manual vehicle type as the toll vehicle type and the remote billing amount as the final toll amount.

[0099] T6: For towed trucks, there may be toll evasion behaviors such as changing trailers during the journey. It is necessary to check the exit axle type according to the weighing axle type and the machine axle type according to certain rules. Those that pass the check proceed to T8; those that fail the check proceed to T7. A current flowchart for checking the axle type of exit towed trucks is shown in Figure 4 , The detailed steps of T6 are as follows:

[0100] T601: When there is a machine axle type, proceed to T602. When there is no machine axle type, determine whether the weighing axle type is the same as the entrance axle type. If they are the same, proceed to T8; otherwise, proceed to T7.

[0101] T602: If the machine axle type is the same as both the weighing axle type and the entrance axle type, proceed to T8; otherwise, proceed to T7.

[0102] T7: The lane toll system notifies the on-duty toll collector that manual judgment of the vehicle type or axle type is required, and the toll collector confirms the toll vehicle type and axle type of the vehicle remotely.

[0103] T8: The lane toll system calculates the final toll amount according to the toll vehicle type, collects the fee, clears or recovers the highway toll media (CPC card or OBU device), and raises the barrier to let the vehicle leave the highway.

[0104] The present invention adopts the above technical solutions and has the following technical advantages: 1. Currently, the devices for collecting vehicle axle type and vehicle type information on the lane site are mainly weighbridges and video vehicle type identifiers. Among them, the weighbridge can only distinguish the vehicle axle type, and the accuracy rate is about 95%; the video vehicle type identifier can distinguish the vehicle axle type and vehicle type, and the accuracy rate is about 95% - 97%. The accuracy rates of both are not sufficient to be used as the basis for independently determining the vehicle type. However, the present invention compares and analyzes the data of the two, reducing the possibility of misjudgment on site. 2. Using historical passing big data to analyze the historical reliable vehicle type is only applicable to non-tractor trucks that often use the highway. The present invention effectively solves the limitations of the vehicle type determination scheme based on historical big data through the combination of historical big data and on-site judgment. 3. The present invention also designs a vehicle type verification scheme for the toll station exit lane system, so that even if the vehicle type is misjudged at the entrance, the vehicle can still be corrected through verification at the exit, thus ensuring the accuracy of the final vehicle toll calculation. 4. The present invention enables both the toll station entrance and exit lane systems to automatically distinguish and verify the vehicle type, so that the toll station lanes can be unattended, reducing the number of toll collectors and the working intensity of toll collectors.
