Description

Technical Field

[0001] The present application relates to the technical field of intelligent traffic control, and in particular to a method for diagnosing problems at intersections. Background Art

[0002] With the development of social science and technology, the continuous expansion of traffic arteries and the increasing number of vehicles, various intersection problems have emerged. The main causes of intersection problems include traffic signal timing problems and traffic organization channelization problems. At present, all cities and municipalities are carrying out intersection problem diagnosis work. The existing technology for diagnosing intersection problems mainly starts from the performance of intersection traffic status, that is, first identify whether there are traffic problems such as congestion, overflow, empty, imbalance, etc. at the intersection, and then the traffic control personnel diagnose whether there are specific intersection problems.

[0003] The problems with the existing intersection problem diagnosis solutions are: on the one hand, intersection problem diagnosis is only performed after the traffic status becomes abnormal, which causes a lag and poor real-time performance of problem diagnosis; on the other hand, intersection problem diagnosis relies on traffic control personnel, which consumes a lot of manpower and has low efficiency. Summary of the invention

[0004] The present application provides a method for diagnosing intersection problems, which is used to solve the problems of diagnosing intersection problems only after the traffic status becomes abnormal, which results in lag, poor real-time problem diagnosis, high manpower consumption and low efficiency.

[0005] In a first aspect, the present application provides a method for diagnosing a road intersection problem, the method comprising:

[0007] Determining the target intersection to be diagnosed and target road type information of the target intersection according to the information of the target intersection;

[0008] Acquire actual configuration parameters of the target intersection corresponding to the target problem; acquire target configuration parameters of the target intersection corresponding to the target problem according to pre-saved standard configuration parameters of the intersections corresponding to the respective intersection problems of the respective road type information;

[0009] If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally; otherwise, it is determined that the actual configuration parameters are configured abnormally.

[0010] The above technical solution has the following advantages or beneficial effects:

[0011] Based on the received instruction to diagnose the intersection problem, the electronic device can obtain the information of the target problem and the target intersection to be diagnosed carried in the instruction, and then determine the target intersection to be diagnosed and the target road type information of the target intersection based on the information of the target intersection. After determining the target intersection, the actual configuration parameters corresponding to the target problem of the target intersection can be obtained. The standard configuration parameters corresponding to each intersection problem of the intersection with each road type information are pre-stored, so the target configuration parameters corresponding to the target problem of the target intersection can be obtained based on the target road type information of the target intersection. If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally, otherwise it is determined that the actual configuration parameters are configured abnormally. The present application can flexibly set the information of the target problem and the target intersection to be diagnosed according to different needs, that is, different information can be carried in the instruction to diagnose the intersection problem. Then, based on the information of the target problem and the target intersection to be diagnosed carried in the instruction, combined with the pre-saved standard configuration parameters corresponding to each intersection problem for intersections of various road type information, the diagnosis of the actual configuration parameters corresponding to the target problem at the target intersection can be achieved. There is no need to wait until traffic congestion occurs before conducting manual investigation, which improves the flexibility and real-time nature of intersection diagnosis. There is no need to rely on traffic control personnel to diagnose intersection problems, which reduces labor costs and improves the efficiency of intersection problem diagnosis.

[0077] Figure 1 The first intersection problem diagnosis process provided by this application is a schematic diagram, and the process includes the following steps:

[0078] S101: receiving an instruction to diagnose a road intersection problem, and obtaining information of a target problem and a target road intersection to be diagnosed carried in the instruction;

[0079] S102: Determine the target intersection to be diagnosed and target road type information of the target intersection according to the information of the target intersection;

[0080] S103: Acquire actual configuration parameters of the target intersection corresponding to the target problem; acquire target configuration parameters of the target intersection corresponding to the target problem according to pre-stored standard configuration parameters of intersections of various road type information corresponding to various intersection problems;

[0081] S104: If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally; otherwise, it is determined that the actual configuration parameters are configured abnormally.

[0082] The intersection problem diagnosis method provided in the present application is applied to an electronic device, which may be a PC, a computer or other device, or a server.

[0083] The electronic device can obtain the target problem and the target intersection to be diagnosed information carried in the instruction according to the received instruction for diagnosing the intersection problem, and then determine the target intersection to be diagnosed and the target road type information of the target intersection according to the information of the target intersection. After determining the target intersection, the actual configuration parameters of the target intersection corresponding to the target problem can be obtained.

[0084] For example, the target problem carried in the instruction is to diagnose the green light time, and the information of the target intersection to be diagnosed carried in the instruction is the identification information of the target intersection to be diagnosed, and the identification information is, for example, "the intersection of a certain road and a certain road". The target intersection can be determined according to the identification information of the target intersection to be diagnosed, that is, the intersection of a certain road and a certain road is used as the target intersection. After determining the target intersection, the actual configuration parameters corresponding to the target problem of the target intersection are obtained according to the target problem, that is, the actual green light time of "the intersection of a certain road and a certain road" is obtained, for example, 30 seconds. In addition, the electronic device can pre-save the road type information of each intersection, and after determining the target intersection, the target road type information of the target intersection is also determined. The target road type information is, for example, the specified intersection shape information, and the intersection shape information is, for example, cross-shaped, T-shaped, X-shaped, Y-shaped, roundabout, 5-fork type, other special shapes, etc. For example, it is determined that the target road type information of the target intersection is T-shaped. The electronic device may pre-save standard configuration parameters corresponding to various intersection problems at intersections of various road type information, for example, the standard configuration parameter of a T-shaped intersection is a standard green light time of 40 seconds.

[0085] Determine whether the actual configuration parameters match the target configuration parameters. If the actual configuration parameters match the target configuration parameters, determine that the actual configuration parameters are configured normally. Otherwise, determine that the actual configuration parameters are configured abnormally. Optionally, if the actual configuration parameters are the same as the target configuration parameters, it means that the actual configuration parameters match the target configuration parameters. Alternatively, for timing configuration parameters, if the time difference between the actual configuration parameters and the target configuration parameters is less than a preset time threshold, it means that the actual configuration parameters match the target configuration parameters. If the time difference between the actual configuration parameters and the target configuration parameters is not less than a preset time threshold, it means that the actual configuration parameters do not match the target configuration parameters.

[0086] Because the present application pre-stores the standard configuration parameters corresponding to each intersection problem of each road type information, the target configuration parameters corresponding to the target problem of the target intersection can be obtained according to the target road type information of the target intersection. If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally, otherwise it is determined that the actual configuration parameters are configured abnormally. The present application can flexibly set the information of the target problem and the target intersection to be diagnosed according to different needs, that is, different information can be carried in the instruction for diagnosing the intersection problem. Then, according to the target problem and the information of the target intersection to be diagnosed carried in the instruction, combined with the standard configuration parameters corresponding to each intersection problem of the intersection of each road type information pre-stored, the diagnosis of the actual configuration parameters corresponding to the target problem of the target intersection can be realized, without waiting for traffic congestion to conduct manual investigation, thereby improving the flexibility and real-time nature of intersection diagnosis, and without relying on traffic control personnel to diagnose intersection problems, thereby reducing labor costs and improving the efficiency of intersection problem diagnosis.

[0087] Figure 2 A schematic diagram of the second intersection problem diagnosis process provided by this application, the process includes the following steps:

[0088] S201: receiving a login instruction of a road intersection problem diagnosis system, and obtaining login information carried in the login instruction; if the login information is verified, displaying a function page of the road intersection problem diagnosis system, wherein the function page of the road intersection problem diagnosis system includes a sub-function page for receiving the instruction to diagnose the road intersection problem;

[0089] S202: receiving an instruction to diagnose a problem at an intersection, and obtaining information of a target problem and a target intersection to be diagnosed carried in the instruction;

[0090] S203: Determine the target intersection to be diagnosed and target road type information of the target intersection according to the information of the target intersection;

[0091] S204: Acquire actual configuration parameters of the target intersection corresponding to the target problem; acquire target configuration parameters of the target intersection corresponding to the target problem according to pre-stored standard configuration parameters of intersections of various road type information corresponding to various intersection problems;

[0092] S205: If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally; otherwise, it is determined that the actual configuration parameters are configured abnormally.

[0093] In order to facilitate receiving instructions for diagnosing intersection problems, the present application sets up an intersection problem diagnosis system. When a user opens the intersection problem diagnosis system, he first enters login information. The login information includes a login user name and a login password. The electronic device can pre-save login information of various targets with login authority. After receiving the login information entered by the user, it is determined whether the login information entered by the user is included in the login information of each target. If so, it means that the login information verification has passed, and the intersection problem diagnosis system has successfully logged in, and the function page of the intersection problem diagnosis system is displayed. If the login information entered by the user is not included in the login information of each target, it means that the login information verification has not passed, and the intersection problem diagnosis system has failed to log in, and a prompt message for characterizing the input error of the login information can be output. The function page of the intersection problem diagnosis system includes a sub-function page for receiving instructions for diagnosing intersection problems. The user can enter instructions for diagnosing intersection problems on the sub-function page. It should be noted that the function page of the intersection problem diagnosis system can also include a sub-page for displaying the intersection problem diagnosis results. After the electronic device determines that the actual configuration parameters are configured normally, or determines that the actual configuration parameters are configured abnormally, the diagnosis result is displayed on the display sub-page of the intersection problem diagnosis result.

[0094] Before receiving the instruction to diagnose the intersection problem, the login instruction of the intersection problem diagnosis system is first received. After the intersection problem diagnosis system is successfully logged in, the function page of the intersection problem diagnosis system is displayed, and the function page includes a sub-function page for receiving the instruction to diagnose the intersection problem. The user can input the instruction to diagnose the intersection problem to the electronic device on the sub-function page, which improves the convenience of the electronic device receiving the instruction.

[0095] Figure 3 A schematic diagram of the third intersection problem diagnosis process provided by this application, the process includes the following steps:

[0096] S301: receiving a login instruction of a road intersection problem diagnosis system, and obtaining login information carried in the login instruction; if the login information is verified, displaying a function page of the road intersection problem diagnosis system, wherein the function page of the road intersection problem diagnosis system includes a sub-function page for receiving the instruction to diagnose the road intersection problem;

[0097] S302: receiving an instruction to diagnose a problem at an intersection, and obtaining information of a target problem and a target intersection to be diagnosed carried in the instruction; wherein, when a first text content is input in the problem input window of the sub-function page, the target problem is determined according to the first text content; or, when a problem selection instruction is received, a problem list is displayed in the sub-function page, and when a problem is selected from the problem list, the target problem is determined according to the selected problem;

[0098] S303: Determine the target intersection to be diagnosed and target road type information of the target intersection according to the information of the target intersection;

[0099] S304: Acquire actual configuration parameters of the target intersection corresponding to the target problem; acquire target configuration parameters of the target intersection corresponding to the target problem according to pre-stored standard configuration parameters of intersections of various road type information corresponding to various intersection problems;

[0100] S305: If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally; otherwise, it is determined that the actual configuration parameters are configured abnormally.

[0101] In order to improve the flexibility of acquiring the target problem carried in the instruction, the present application provides two methods. Method 1: Determine the target problem based on the first text content entered by the user in the question input window of the sub-function page; Method 2: Display a list of questions on the sub-function page, and determine the target problem based on the question selected by the user in the question list. The user can choose any method to input instructions for diagnosing intersection problems, and the electronic device can acquire the target problem carried in the instruction. This makes user operation more flexible, improves user experience, and also improves the flexibility of acquiring the target problem carried in the instruction.

[0102] Taking the first method as an example, if the first text content input by the user in the question input window of the sub-function page is "green light time", then "green light time" is determined as the target question.

[0103] Taking the second method as an example, a question list selection button can be displayed in the sub-function page. When it is recognized that the question list selection button is clicked, it is determined that the question selection instruction is received, and the question list is displayed in the sub-function page. For example, the question list includes green light time, red light time, yellow light time, etc. When it is recognized that a question is selected from the question list, it is determined that the selected question is red light time, and at this time, "red light time" is determined as the target question.

[0106] S402: receiving an instruction to diagnose a problem at an intersection, and obtaining information of a target problem and a target intersection to be diagnosed carried in the instruction; wherein, when a first text content is input into a problem input window of the sub-function page, obtaining each pre-stored problem, determining first similarities between the first text content and each problem, and determining the target problem according to the problem with the largest first similarity; or, when a problem selection instruction is received, displaying a problem list in the sub-function page, and when a problem is selected from the problem list, determining the target problem according to the selected problem;

[0109] S405: If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally; otherwise, it is determined that the actual configuration parameters are configured abnormally.

[0110] In the present application, based on the first similarities between the input first text content and the pre-saved first similarities of various questions, the question with the largest first similarity is determined as the target question, thereby improving the accuracy of the determined target question.

[0111] Optionally, for each pre-saved question, the number of identical characters between the character content of the question and the first text content, as well as the total number of characters between the character content of the question and the first text content are calculated; the ratio of the number of identical characters to the total number is used as the first similarity between the input first text content and the question. In this way, the first similarity corresponding to each question can be obtained. The question with the largest first similarity is selected as the target question.

[0112] Optionally, if there is one question with the greatest first similarity, the question with the greatest first similarity can be determined as the target question. If there are multiple questions with the greatest first similarity, multiple questions with the greatest first similarity can be displayed on the sub-function page, and then the user can select from the multiple questions with the greatest first similarity, and the question selected by the user is determined as the target question.

[0129] Figure 7 The seventh intersection problem diagnosis process provided by this application is a schematic diagram, and the process includes the following steps:

[0130] S701: receiving a login instruction of a road intersection problem diagnosis system, and obtaining login information carried in the login instruction; if the login information is verified, displaying a function page of the road intersection problem diagnosis system, wherein the function page of the road intersection problem diagnosis system includes a sub-function page for receiving the instruction to diagnose the road intersection problem;

[0131] S702: receiving an instruction to diagnose a road intersection problem, and obtaining target range information and target road type information of a target road intersection to be diagnosed carried in the instruction; wherein, when a second text content is input in the road type information input window of the sub-function page, the target road type information is determined according to the second text content; or, when a road type information selection instruction is received, a road type information list is displayed in the sub-function page, and when road type information is selected from the road type information list, the target road type information is determined according to the selected road type information;

[0132] S703: Determine the target intersection whose road category information within the target range information is the target road type information according to the target range information and the target road type information of the target intersection and the road type information of each intersection stored in advance;

[0133] S704: Acquire actual configuration parameters of the target intersection corresponding to the target problem; acquire target configuration parameters of the target intersection corresponding to the target problem according to pre-stored standard configuration parameters of intersections of various road type information corresponding to various intersection problems;

[0134] S705: If the actual configuration parameters match the target configuration parameters, it is determined that the actual configuration parameters are configured normally; otherwise, it is determined that the actual configuration parameters are configured abnormally.

[0135] In order to improve the flexibility of acquiring the target road type information carried in the instruction, the present application provides two methods. Method 1: Determine the target road type information according to the second text content entered by the user in the road type information input window of the sub-function page; Method 2: Display the road type information list on the sub-function page, and determine the target road type information according to the road type information selected by the user in the road type information list. The user can choose any method to input instructions for diagnosing intersection problems, and the electronic device can obtain the target road type information carried in the instruction. This makes user operation more flexible, improves user experience, and also improves the flexibility of acquiring the target road type information carried in the instruction.

[0136] Taking the first method as an example, if the second text content input by the user in the question input window of the sub-function page is "the shape of the intersection is Y-shaped", then "the shape of the intersection is Y-shaped" is determined as the target road type information.

[0137] Taking the second method as an example, a road type information list selection button can be displayed in the sub-function page. When it is recognized that the road type information list selection button is clicked, it is determined that the road type information selection instruction is received, and the road type information list is displayed in the sub-function page. For example, the road type information list includes road grade one, road grade two, X-shaped intersection, Y-shaped intersection, intersection width 40 meters, intersection width 50 meters, etc. When it is recognized that the road type information is selected from the road type information list, it is determined that the selected road type information is a Y-shaped intersection, and the "Y-shaped intersection" is determined as the target road type information.

[0138] It should be noted that the target type information selected by the user can be one or more. According to the target range information and target road type information of the target intersection, and the road type information of each intersection saved in advance, the target intersection whose road category information within the target range information is the target road type information is determined. At this time, the target intersections determined are generally multiple.

[0146] Optionally, for each pre-saved road type information, the number of identical characters between the character content contained in the road type information and the second text content, as well as the total number of characters contained in the character content contained in the road type information and the second text content are calculated; the ratio of the number of identical characters to the total number is used as the second similarity between the input second text content and the road type information. In this way, the second similarity corresponding to each road type information can be obtained. The road type information with the largest second similarity is selected as the target road type information.

[0147] Optionally, if there is one piece of road type information with the second greatest similarity, the road type information with the second greatest similarity can be determined as the target road type information.
