Abstract

The present invention proposes a temporary traffic control method for roads around the examination site based on the declaration of the vehicles transporting candidates to the examination site, that is, temporary traffic control is carried out on the roads around the examination site during large-scale examinations, and the candidates on the vehicles or the personnel transporting candidates to the examination site apply for the right of way after being processed by the background management system. During the control period, all vehicles entering the controlled roads will be detected and verified by video, and those who enter the controlled roads without permission will be subject to certain penalties. The present invention restricts the use of other social vehicles by applying in advance, which can not only alleviate the traffic congestion around the examination site during the examination, but also achieve the purpose of ensuring that candidates can arrive at the examination site smoothly.

Description

Technical Field

[0001] The present invention relates to the field of traffic management and control, and in particular to traffic control of congested sections of roads around an examination room and verification of admitted vehicles. Background Art

[0002] In recent years, the number of candidates for the high school entrance examination and college entrance examination has continued to increase sharply. In the past five years, the total number of candidates for the college entrance examination has increased by hundreds of thousands each year. During the high school entrance examination and college entrance examination, various issues related to the examination and candidates have become topics of concern and discussion in all walks of life. At these critical moments in academic career, all aspects of society have taken relevant measures to try their best to eliminate unstable factors and ensure the smooth progress of the examination.

[0003] During the examination period, each examination center accommodates a large number of candidates, the examination time is clear, and most candidates are sent to the examination center by their parents. Therefore, the traffic volume on the roads around the examination center will increase significantly in a short period of time. In addition, other social vehicles passing by will easily cause traffic congestion around the examination center, and even cause delays for candidates. In order to alleviate this problem and ensure that candidates can enter the examination room on time and smoothly, the present invention proposes a temporary traffic control method for the road sections around the examination room based on the declaration of the vehicles sending candidates to the examination room, and adopts the method of applying for verification for the vehicles carrying candidates to enter the controlled road sections, and imposes management measures on other social vehicles to restrict the passage within the specified time.

[0004] The vehicle taking the test taker to the test takes the relevant information of the test taker and the vehicle through the mobile phone software for authentication and applies for permission to enter the controlled roads during the control period. If the application is approved, the vehicle will be allowed to enter the controlled road section access whitelist. During the control period, all vehicles entering the controlled roads will be detected and verified by video, and those who enter the controlled roads without permission will be subject to certain penalties. Summary of the invention

[0005] The present invention proposes a temporary traffic control method for the road sections around the examination site based on the declaration of the vehicles transporting the examinees, that is, during the large-scale examination, the roads around the examination site are controlled, and the vehicles transporting the examinees apply for access to obtain the right of way, and other social vehicles are subject to traffic restriction control measures. In this way, the purpose of alleviating traffic congestion around the examination site during the examination is achieved, and the examinees are guaranteed to arrive at the examination site smoothly.

[0006] The technical solution adopted by the system of the present invention is a traffic control system for test site sections based on the declaration of test-taking vehicles, which is characterized by including: an application module, a verification module, a background management system, and a feedback module.

[0007] The application module is a mobile phone software for traffic control for candidates, and the candidates or the personnel who escort them to the exam submit the application;

[0008] The verification module is a roadside camera, which is set at the starting point of the traffic control section to identify the license plate number of the arriving vehicle;

[0009] The backend management system can process the application information and verification information provided by the vehicle;

[0010] The feedback module is a backend management system that notifies the applicant whether the vehicle is on the whitelist of the controlled road section through the traffic control mobile phone software.

[0011] The technical solution of the method of the present invention is a temporary traffic control method for the road sections around the examination center based on the declaration of the vehicles taking the test, which specifically includes the following steps:

[0012] Step 1: Submit an application for passage through traffic control sections

[0013] a. The candidate or the person escorting the candidate to the test should submit an application and fill in the license plate number;

[0014] b. Fill in the candidate's admission ticket number and ID number;

[0015] c. Select the target test site;

[0016] d. Select the estimated arrival time;

[0017] e. Submit application;

[0018] f. If approved, the vehicle will be included in the whitelist for access to the controlled road section.

[0019] In step b and c of step 1, if there are multiple candidates in the car, if multiple candidates take the test at the same test site, at least one candidate's information should be filled in; if multiple candidates take the test at multiple different test sites, at least one candidate's information should be filled in at each test site. Each candidate's information can be bound to multiple vehicles, but only one vehicle bound to it is allowed to pass the applied section once in a period of time.

[0020] In step d described in step 1, the software platform will provide optional time ranges, which are: one hour before the start of the test (t1) to half an hour before the start of the test (t2), half an hour before the start of the test to the start time of the test, half an hour before the end of the test (t3) to the end time of the test, and one hour after the end of the test (t5). A certain application capacity limit is set for each application period. When the number of applications in a certain period reaches the upper limit, subsequent applications for that period will no longer be available. Applicants need to reasonably choose the expected arrival period according to their own circumstances. Each test can choose one period before and one period after the test. If there are multiple tests in one day, each test needs to be selected. Vehicles that have not applied or have not applied successfully in a certain application period will not be allowed to pass. The above specific time ranges are for reference only. For the specific calculation methods of t1, t2, t3, t4, and t5, please refer to the control time determination method in the detailed description of step 2.

[0021] The method for determining the capacity of each time period is as follows: before and after the start of the exam, the total number of candidates in the examination room is used as the total capacity, and it is allocated to each time period according to a certain ratio. The specific ratio is determined by referring to the time distribution of candidates arriving and leaving the examination room in previous similar exams.

[0022] In step e described in step 1, the application should be submitted as early as possible, no later than ten minutes before arriving at the control starting point, so that the backend management system can review and approve the application information. For candidates who take a taxi to the test site, they only need to fill in the admission application when getting on the car, fill in the license plate number of the taxi in the license plate number column, and fill in the rest according to their real information.

[0023] Step 2: Verify the vehicle during the traffic control period

[0024] a. Use the license plate information captured by the roadside camera to determine whether the vehicle is on the whitelist of the controlled road section during the period: if yes, continue to the subsequent steps; if not, register the vehicle for subsequent processing;

[0025] b. Determine whether the vehicle only passes through once in one direction during the period: if yes, the vehicle is allowed to pass; if no, the vehicle is registered;

[0026] The scope of the controlled road section in step 2 can be defined in the following way:

[0027] First, the controlled roads are the roads that must be taken to reach the test site from the periphery of the test site. The starting and ending sections of the controlled road sections can be determined by the following formula:

[0028]

[0029] Y≥Y v

[0030]

[0031] Among them, N s is the number of candidates that the test center can accommodate, w is the proportion of candidates who are sent to the test by private cars, S is the saturated flow of the section, and Y v Q is the maximum flow ratio of the road section when vehicles can pass smoothly without stopping. v The maximum flow rate that vehicles can pass through the road section at a smooth speed. The meaning of this demarcation method is that when the expected flow rate ratio of a road section during the test period is greater than the flow rate ratio when vehicles can pass smoothly, control will be implemented on this section.

[0032] The number of lanes where control measures are implemented on the controlled section can be determined by the following formula:

[0033]

[0034] Yf ≤Y s ≤Y v

[0035] k = nm

[0036] m≤n

[0037] Where N is the number of vehicles that apply to pass the controlled section during this period, q i is the traffic volume of the i-th lane, S is the saturated flow of the section; Y v Y is the maximum flow ratio of the road section when vehicles can pass smoothly without stopping. f is the flow ratio of the road section when vehicles can pass at free flow speed, n is the number of lanes in the section, and k is the number of lanes controlled in the section when m reaches the maximum value within the constraint.

[0038] The control time range of the controlled road section can be determined by the following methods:

[0039]

[0040] Among them, Q t is the traffic volume at the starting section at time t when there is no traffic control, S is the saturated flow of the section, and Y t is the flow ratio at the starting section at time t.

[0041]

[0042] In the above formula, α is the proportional coefficient that represents the degree of congestion of the road section at the current time t. Let the time when α=α1 be t1, the time when α=α2 be t2, the time when α=α3 be t3, the time when α=α4 be t4, and the time when α=α5 be t5.

[0043] Beneficial effects of the present invention:

[0044] The temporary traffic control method for the road sections around the examination site based on the application of the test-taking vehicles proposed in the present invention focuses on the congestion problem of the road sections near the examination site, and implements traffic control on the congested road sections through the active application and automatic verification of the test-taking vehicles. It not only ensures that the test-taking vehicles can smoothly and punctually deliver the candidates to the examination site during the examination, but also alleviates the traffic chaos caused by unclear control information and the time-consuming and labor-intensive manual guidance.

[0048] The system schematic diagram of the present invention is as follows Figure 1 As shown, the technical solution adopted in the specific implementation mode of the present invention is a traffic control system for examination road sections based on the identification of examination vehicles, which is characterized by including: an application module, a verification module, a background management system, and a feedback module.

[0049] The application module is a mobile phone software for traffic control for candidates, and the candidates or the personnel who escort them to the exam submit the application;

[0050] The verification module is a roadside camera, which is set at the starting point of the traffic control section to identify the license plate number of the arriving vehicle;

[0053] When a vehicle is about to reach the control starting point, the roadside camera will transmit the collected data to the background management system via wireless transmission. The background management system will determine whether the vehicle is on the whitelist of the controlled section based on the data provided by the verification module, and feedback to the applicant and the background management system through the mobile phone software.

[0054] like Figure 2 As shown in the figure, the flowchart of the application of vehicles taking the test to pass the controlled road section is as follows:

Each candidate's information can be bound to multiple vehicles, but only one vehicle bound to it is allowed to pass the applied section once in a period of time.

[0062] Figure 2 In step d described in, the software platform will provide optional time ranges, which are: one hour before the start of the test (t1) to half an hour before the start of the test (t2), half an hour before the start of the test to the start time of the test, half an hour before the end of the test (t3) to the end time of the test, the end time of the test to half an hour after the end of the test, and half an hour after the end of the test (t4) to one hour after the end of the test (t5). A certain application capacity limit is set for each application period. When the number of applications for a certain period reaches the upper limit, subsequent applications for that period will no longer be available. Applicants need to reasonably choose the expected arrival time period according to their own circumstances. Each test can choose one time period before and one time period after the start of the test. If there are multiple tests in one day, each test must be selected. Vehicles that have not applied or have not applied successfully in a certain application period will not be allowed to pass. The above specific time ranges are for reference only. For the specific calculation methods of t1, t2, t3, t4, and t5, see Figure 3 The method for determining the control time in the detailed description.

For candidates who take a taxi to the test site, they only need to fill in the admission application when getting on the taxi, fill in the license plate number of the taxi in the license plate number column, and fill in the rest according to their real information.

[0065] like Figure 3 As shown in the figure, the vehicle verification flow chart during the road section traffic control period, the steps are as follows:

[0066] a. Use the license plate information captured by the roadside camera to determine whether the vehicle is on the whitelist of the controlled road section during the period: if yes, continue to the subsequent steps; if not, register the vehicle for subsequent processing;

[0067] b. Determine whether the vehicle only passes through once in one direction during the period: if yes, the vehicle is allowed to pass; if no, the vehicle is registered;

The meaning of this demarcation method is that when the expected flow rate ratio of a road section during the test period is greater than the flow rate ratio when vehicles can pass smoothly, control will be implemented on this section.

[0074] The number of lanes where control measures are implemented on the controlled section can be determined by the following formula:

[0075]
