Description

Technical Field

[0002] Currently, the installation of various traffic facilities on roads relies on manual judgment, and some facilities may be installed based on temporary situations. However, there is no scientific basis for judging whether the installed traffic facilities are reasonable.

[0049] This application provides a method for adjusting traffic facilities, such as... Figure 1 As shown, the method may include steps S101-S103:

[0050] S101. Obtain the target locations of all available traffic facilities within the preset area;

[0051] S102. Determine the traffic facility setting status corresponding to each target location. The traffic facility setting status includes: whether the target location has the traffic facility and the type of traffic facility set when the target location has the traffic facility.

[0052] S103. Based on the status of traffic facility settings and traffic event occurrences corresponding to each target location, determine the adjustment strategy for the indicator level and traffic facility settings corresponding to each target location.

[0053] In an exemplary embodiment of this application, the step of determining the adjustment strategy for the indicator level and traffic facility setting status corresponding to each target location based on the traffic facility setting status and traffic event occurrence status corresponding to each target location includes:

[0054] Determine the occurrence attributes at each target location; the traffic event is one or more events set under preset indicators;

[0055] Based on the status of traffic facility settings corresponding to the target location and the occurrence attribute, determine the indicator level adjustment strategy for the preset indicator corresponding to the target location;

[0056] The adjustment strategy for the setting status of the transportation facilities corresponding to the target location is determined based on the indicator level adjustment strategy.

[0057] In an exemplary embodiment of this application, the above-mentioned indicator level adjustment strategy includes maintaining the current indicator level, lowering the current indicator level, and raising the current indicator level; the above-mentioned traffic facility setting status adjustment strategy includes maintaining the current traffic facility setting status and changing the current traffic setting status.

[0058] In an exemplary embodiment of this application, the traffic event occurrence status may include, but is not limited to, the occurrence attributes of traffic events corresponding to one or more preset indicators. The occurrence attributes corresponding to different traffic events will be described in detail in the following content.

[0059] In an exemplary embodiment of this application, the solution of this application analyzes traffic events at target locations and obtains indicator level adjustment strategies for different preset indicators at each target location based on the current status of traffic facility settings and the occurrence of traffic events. Based on different indicator level adjustment strategies, it can promptly determine whether the current traffic facility settings at the target location are reasonable. If it is determined to be unreasonable, it can provide a corresponding adjustment strategy for the current traffic facility settings based on the indicator level adjustment strategy, thereby reducing traffic accident risks and significantly improving traffic safety, smoothness, and convenience.

[0060] In an exemplary embodiment of this application, the traffic facility may include, but is not limited to, pedestrian crossings, railings, underpasses, and overpasses.

[0061] In an exemplary embodiment of this application, before making a reasonable assessment of the traffic facilities at the target location, one or more target locations can be obtained within a preset area. The preset area can be a city, a district, a street, etc., and no specific restrictions are placed on the preset area.

[0062] In an exemplary embodiment of this application, the step of obtaining the target locations of all possible locations for traffic facilities within a preset area is as follows: Figure 2 As shown, it may include steps S201-S204:

[0063] S201. Obtain a preset first location point using map data; the first location point may include any one or more of the following: park entrance / exit, vehicle parking station, and subway station entrance / exit.

[0064] S202. Determine the road where the first location point is located based on road network data, and detect whether a second location point is set within a preset range on the side of the road where the first location point is not set; the second location point may include any one or more of the following: park entrance / exit, vehicle parking station, and subway station entrance / exit;

[0065] S203. When the second location point is set within a preset range on the side of the road where the first location point is not set, the second location point and the first location point are combined to form the location pair.

[0066] S204. Determine the position pair as the target position.

[0067] In an exemplary embodiment of this application, map data can be used to find all the park entrances and exits (the park may include, but is not limited to, residential communities, science and technology parks, enterprises, schools, etc.), vehicle parking stations (the vehicles may include, but are not limited to, buses, taxis, private cars, school buses, etc.) and subway station entrances and exits within a preset area, and obtain the coordinates of these locations (which may be called first location points), for example, including but not limited to latitude and longitude coordinates, satellite coordinates, etc.

[0068] In an exemplary embodiment of this application, after obtaining the first location point, road network data can be combined to search from one side of the road whether there is another such location point within a preset range opposite to these first location points, which can form a flow of people with the first location point, and can be defined as the second location point. For example, if the current first location point is a bus stop, it is possible to find whether there is another bus stop or a subway station entrance / exit within a preset range on the other side of the road opposite to the bus stop.

[0069] In an exemplary embodiment of this application, the preset range may refer to: obtaining the intersection point of a straight line passing through a first location point and perpendicular to the road with the other side of the road (the side without the first location point), and extending a preset distance (the width of the extension can be customized, generally much smaller than the preset distance) along the road network direction on the other side of the road from this intersection point as the starting point. This preset distance may include, but is not limited to, 50 meters. The value of this preset distance can be defined according to different application scenarios and is not specifically limited here. Figure 3 As shown, area a is the preset range determined based on intersection 2.

[0070] In an exemplary embodiment of this application, if a second location point exists within a preset range on the other side of the road, the first location point and the second location point can be combined into a location pair and saved. One or more location pairs obtained can be used as target locations.

[0071] In exemplary embodiments of this application, as Figure 3 As shown, you can traverse the intersections and platform locations on both sides of the main road within the preset area on the preset map, and check if there are any location pairs that meet the conditions. For example, starting from intersection 6, you can traverse all the location points. When you find intersection 2, intersection 1 meets the condition of forming a location pair. In this way, intersection 1 and intersection 2 form a location pair. Similarly, intersection 4 and platform 2 also form a location pair. In the map above, a total of two location pairs are formed. You can save these location pairs as target locations for later analysis.

[0072] In an exemplary embodiment of this application, the target locations of all available transportation facilities within a preset area can also be obtained by obtaining manually input location attributes (e.g., platform, stop, intersection, entrance / exit, etc., or directly inputting more specific content, such as the entrance of XX school) and directly searching on a preset map, and marking the searched locations, thereby using all search results as target locations.

[0073] In an exemplary embodiment of this application, after determining the target location, it is possible to further determine whether traffic facilities are set up at each target location, and what kind of traffic facilities are set up, so as to obtain complete information on the setting status of traffic facilities at these target locations, thereby improving the accuracy of subsequent scheme judgment.

[0074] In exemplary embodiments of this application, as Figure 4 As shown, determining the traffic facility setup status for each target location may include steps S301-S303:

[0075] S301. Obtain the coordinate data of each target location;

[0076] S302. Based on the coordinate data, obtain an image of the target location using a preset panoramic map;

[0077] S303. Input the image into a preset traffic facility detection model, identify and output whether the traffic facility is set at the target location, and the type of traffic facility set when the traffic facility is set at the target location.

[0078] In an exemplary embodiment of this application, before executing the above-described embodiment, a large number of images with various traffic facility settings can be used as training images to train a pre-established neural network model to obtain the traffic facility detection model. This allows the embodiment of this application to directly output detection results through the traffic facility detection model after obtaining images of the target location, thereby determining the traffic facility settings at each target location.

[0079] In an exemplary embodiment of this application, determining the traffic facility installation status of each target location may further include: directly acquiring all traffic facility installation locations within a preset area through road network data, and matching the acquired traffic facility installation locations with the acquired target locations. If any traffic facility installation location matches any target location, it can be determined that the traffic facility installation location and the target location belong to the same location, thereby determining the traffic facilities installed at the target location. Conversely, if any target location does not match any traffic facility installation location, it can be determined that no traffic facilities are installed at the target location.

[0080] In an exemplary embodiment of this application, the type of traffic facility may include any one or more of the following: non-traffic light pedestrian crossing, traffic light pedestrian crossing, railing, underpass, and overpass;

[0081] The traffic facility setup status can include any one or more of the following: no traffic facilities, pedestrian crossings without traffic lights, pedestrian crossings with traffic lights, railings, underpasses, and overpasses.

[0082] In an exemplary embodiment of this application, after determining the traffic facility setup status at each of the target locations, the method may further include:

[0083] Set a corresponding status label based on the traffic facility setup status of each of the determined target locations;

[0084] The status label may include any one or more of the following: no traffic facilities are provided, a pedestrian crossing without traffic lights is provided, a pedestrian crossing with traffic lights is provided, a railing is provided, an underpass is provided, and an overpass is provided.

[0085] In an exemplary embodiment of this application, by setting a status label for each target location, the status of traffic facility settings at each target location can be intuitively determined, thereby improving computational efficiency.

[0086] In an exemplary embodiment of this application, in order to effectively evaluate the rationality of the traffic facility status at each target location, one or more indicators, referred to as preset indicators, can be preset to determine the quality of the current traffic facility status.

[0087] In an exemplary embodiment of this application, for traffic, accident rate, congestion, and traffic flow are three main parameters. Therefore, the target location can be evaluated from three dimensions: accident rate, congestion, and traffic flow (including pedestrian flow and / or vehicle flow), so that reasonable indicators can be set for the target location to reflect the health of the current traffic facility settings.

[0088] In an exemplary embodiment of this application, taking into account the accident rate, congestion, and traffic flow as described above, the preset indicators may include any one or more of the following: safety indicators, smooth traffic flow indicators, and convenience indicators; the indicator levels may correspondingly include any one or more of the following: safety level, smooth traffic flow level, and convenience level.

[0089] In an exemplary embodiment of this application, in order to examine the preset indicators, some traffic events can be set under each preset indicator. The occurrence and attributes of these traffic events are used to determine whether the traffic facility setting status corresponding to the current target location is reasonable under a preset indicator. Different preset indicators may correspond to the same or different traffic events, and different traffic events may correspond to the same or different event attributes.

[0090] In an exemplary embodiment of this application, when the preset indicator includes the security indicator:

[0091] Traffic incidents under the aforementioned safety indicators may include any one or more of the following: vehicle collisions, vehicle-pedestrian collisions, and stampedes.

[0092] The occurrence attributes of traffic events under the safety indicators may include any one or more of the following: accident frequency, accident severity, and accident impact on traffic index;

[0093] When the preset indicator includes the smooth flow indicator:

[0094] Traffic events under the smooth flow index may include: the duration of a vehicle passing through a traffic facility is greater than or equal to a first preset duration threshold, and / or the duration of a person passing through a traffic facility is greater than or equal to a second preset duration threshold.

[0095] The occurrence attributes of traffic events under the smooth flow index may include any one or more of the following: event frequency, event time period, and event duration;

[0096] When the preset indicator includes the convenience indicator:

[0097] Traffic events under the convenience index may include any one or more of the following: vehicle flow is greater than or equal to a first preset flow threshold, pedestrian flow is greater than or equal to a second preset flow threshold, pedestrians illegally cross traffic facilities, vehicles illegally cross traffic facilities, pedestrians illegally cross roads, and vehicles illegally cross roads.

[0098] The occurrence attributes of traffic events under the convenience index may include any one or more of the following: event frequency, event time period, and the number of people and / or vehicles involved in the event within the same time period.

[0099] In an exemplary embodiment of this application, the indicator level adjustment strategy for determining the preset indicator corresponding to the target location based on the traffic facility setting status and the occurrence attribute can include:

[0100] When the occurrence attribute meets the preset requirements, the indicator level is increased;

[0101] If the occurrence attribute fails to meet the preset requirements within a preset time period, the indicator level is reduced.

[0102] In an exemplary embodiment of this application, the preset requirement can be set according to the different occurrence attributes of traffic events under different preset indicators. The details of the preset requirement are not limited here. For example, for vehicle collision accidents under the safety indicator, the preset requirement may refer to an accident frequency of less than or equal to 2 times per month, or to the severity of the accident, such as the number of casualties being less than or equal to 3. For traffic events under the smooth flow indicator where the time it takes for vehicles to pass through traffic facilities is greater than or equal to a first preset time threshold, the preset requirement may refer to an event frequency of less than or equal to 3 times per week and an event duration of less than or equal to 2 hours. For traffic events under the convenience indicator where the vehicle flow is greater than or equal to a first preset flow threshold, the preset requirement may refer to an event frequency of less than or equal to 5 times per week and an event involving less than or equal to 3 people.

[0103] In an exemplary embodiment of this application, the strategy for adjusting the index level of a preset index corresponding to a target location based on the traffic facility setting status and occurrence attributes of the target location can directly adjust the index level of the traffic facility setting status at the target location under the current index according to the occurrence attributes of a traffic event and the preset index level adjustment range. For example, if there is a pedestrian crossing at the current target location, but two traffic accidents occur at the target location within a month, the index level of the pedestrian crossing can be reduced by two levels under the safety index; if there is a guardrail at the current target location, but 2-3 congestion incidents occur at the target location within a week, the index level of the guardrail can be reduced by one level under the smooth flow index.

[0104] In an exemplary embodiment of this application, the adjustment range of the indicator level can be defined by the user according to different indicators, different application scenarios, and different accuracy requirements, and there is no limitation on the specific value.

[0105] In an exemplary embodiment of this application, the strategy for adjusting the index level of a preset index corresponding to a target location based on the traffic facility setting status and occurrence attributes of the target location can also be implemented through a scoring method. The following is a detailed description of this scoring embodiment.

[0106] In an exemplary embodiment of this application, the indicator level adjustment strategy for determining the preset indicator corresponding to the target location based on the traffic facility setting status and occurrence attributes of the target location is as follows: Figure 5 As shown, steps S401-S402 may be included:

[0107] S401. Set the initial index level of the traffic facility setting status corresponding to each target location under each preset index to the highest level, and use a preset scoring strategy to score the traffic facility setting status under the highest level as full marks.

[0108] S402. When the traffic incident occurs at any target location, the scoring strategy is adopted. Based on the full score, the score of the traffic facility setting status corresponding to the target location under the preset index corresponding to the traffic incident is adjusted according to the occurrence attribute of the traffic incident. The higher or lower index score indicates the higher or lower index level.

[0109] In an exemplary embodiment of this application, when the traffic event occurs at any target location, the scoring strategy is adopted, and based on the full score, the score of the traffic facility setting status corresponding to the any target location under the preset index corresponding to the traffic event is adjusted according to the occurrence attribute of the traffic event, including:

[0110] When any of the preset events under the safety indicators occur, the score of the traffic facility setting status corresponding to any target location is reduced by a first preset score, wherein the accident frequency, the accident severity, and the accident impact on traffic index are all positively correlated with the first preset score.

[0111] When any traffic event under the smooth flow index occurs, the score of the traffic facility setting status corresponding to any target location is reduced by a second preset score, wherein the frequency of the event and the duration of the event are positively correlated with the second preset score; and the second preset score is different for different time periods of the event.

[0112] When any traffic event under the convenience index occurs, the score of the traffic facility setting status corresponding to any target location is reduced by a third preset score, wherein the frequency of the event and the number of people and / or vehicles involved in the event within the same time period are positively correlated with the third preset score; and the second preset score is different for different time periods of the event.

[0113] In an exemplary embodiment of this application, the base value (or initial value) of the traffic facility setting status at each target location for each preset indicator can be 100 points.

[0114] In an exemplary embodiment of this application, for example, safety indicators can be measured by the accident rate, which can be calculated by statistically analyzing accidents occurring near the target location. For example, only pedestrian-related accidents can be statistically analyzed. Once an accident occurs, points of safety indicators are deducted according to the level of the accident. For example, 5 points can be deducted for ordinary vehicle accidents with no injuries, 10 points can be deducted for injuries, and 20 points can be deducted for major traffic accidents with multiple injuries.

[0115] In an exemplary embodiment of this application, for example, the smooth flow index can be measured by congestion. Congestion can be judged mainly based on the smoothness of vehicle and / or pedestrian traffic. For example, if there is vehicle congestion during morning and evening rush hours, 2 points can be deducted from the basic score of the smooth flow index. If there is congestion during off-peak hours, 5 points can be deducted. If the congestion period exceeds 50% within a cycle, an additional 10 points will be deducted.

[0116] In an exemplary embodiment of this application, for example, the convenience index can be measured by pedestrian flow, which can be mainly measured by the following aspects: 1. Based on pedestrian flow camera capture, 2 points are deducted from the convenience index when the pedestrian flow value exceeds a threshold; 2. Confirm the number of people crossing between two points by facial capture, and deduct 2 points when the number of people exceeds a certain threshold; 3. Obtain whether there is illegal jaywalking through camera and bus / taxi vehicle operation data, and deduct 5 points if such a situation exists.

[0117] In an exemplary embodiment of this application, the method may further include:

[0118] If no traffic event under any preset indicator occurs at any of the target locations within the second preset time period, the score of the traffic facility setting status corresponding to any target location under any preset indicator will be increased by a fourth preset score; wherein, the score of the traffic facility setting status after the score increase is lower than or equal to the full score, that is, the score under each preset indicator can only be increased to the preset full score at most.

[0119] In an exemplary embodiment of this application, for any preset indicator, the score can be restored over a certain period of time. For example, for the safety indicator, if no accident occurs for a month, 5 points can be restored; for the traffic flow indicator, a one-day recovery period can be set, and if no congestion occurs within a day, 2 points can be restored; for the convenience indicator, a one-week recovery period can be set, and if no situation exceeds the number of people threshold within a week, 2 points can be restored. Of course, all values ​​can be adjusted.

[0120] In an exemplary embodiment of this application, determining the rationality of the traffic facility setting status corresponding to each target location based on the adjusted index level may include performing the following operations for each target location:

[0121] Determine the preset index corresponding to the most frequent traffic events occurring at the target location within the third preset time period;

[0122] The system detects whether the adjusted index level of the preset index is less than or equal to a preset index threshold. If the adjusted index level is greater than the index threshold, the system determines that the traffic facility setting status corresponding to the target location is reasonable under the preset index. If the adjusted index level is less than or equal to the index threshold, the system determines that the traffic facility setting status corresponding to the target location is unreasonable under the preset index.

[0123] According to a preset priority order, the adjusted indicator levels of all preset indicators, excluding the preset indicator corresponding to the most frequently occurring traffic event, are determined to be greater than the preset level thresholds corresponding to the other preset indicators. When the adjusted indicator level of the other preset indicators is greater than the preset level thresholds corresponding to the other preset indicators, the traffic facility setting status corresponding to the target location is determined to be reasonable under the other preset indicators. When the adjusted indicator level of the other preset indicators is less than or equal to the preset level thresholds corresponding to the other preset indicators, the traffic facility setting status corresponding to the target location is determined to be reasonable under the other preset indicators.

[0124] In an exemplary embodiment of this application, adjusting the state of the traffic facility setup may include:

[0125] The status of the traffic facilities is adjusted according to the indicator level adjustment strategy and the priority of the preset indicators.

[0126] In an exemplary embodiment of this application, priorities can be set for each preset indicator in advance. For example, the priority of security indicators is higher than that of smooth traffic indicators, and the priority of smooth traffic indicators is higher than that of convenience indicators.

[0127] In an exemplary embodiment of this application, the above-described traffic facility setting status adjustment scheme is described below through specific embodiments.

[0128] In an exemplary embodiment of this application, for example, if traffic accidents frequently occur at a certain target location, resulting in multiple injuries and fatalities, it indicates that the safety indicators at that target location need to be closely examined. The system can detect whether the level of the currently adjusted safety indicator is less than or equal to a preset first-level threshold. If the level of the adjusted safety indicator is detected to be greater than the first-level threshold, it is determined that the traffic facilities at the target location are reasonable under the current safety indicators, and no adjustments to the current traffic facilities are necessary. If the level of the adjusted safety indicator is detected to be less than or equal to the first-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the current safety indicators, and the safety level needs to be increased. Furthermore, according to the priority of each preset indicator, the system can further detect whether the level of the smooth traffic flow indicator is less than or equal to a preset second-level threshold. If the level of the smooth traffic flow indicator is detected to be greater than the first-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the current safety indicators, and the safety level needs to be increased. When the second-level threshold is reached, it is determined that the traffic facilities at the target location are reasonable under the smooth flow index, and no adjustments to the current traffic facilities regarding the smooth flow index are needed. When the smooth flow index level is detected to be less than or equal to the second-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the smooth flow index, and the smooth flow level needs to be increased. Furthermore, according to the priority of each preset index, the next step is to detect whether the convenience index level is less than or equal to a preset third-level threshold. When the convenience index level is detected to be greater than the third-level threshold, it is determined that the traffic facilities at the target location are reasonable under the convenience index, and no adjustments to the current traffic facilities regarding the convenience index are needed. When the convenience index level is detected to be less than or equal to the third-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the convenience index, and the convenience level needs to be increased.

[0129] In an exemplary embodiment of this application, for example, if traffic congestion frequently occurs at a target location and the smooth traffic level continuously declines, it indicates that the smooth traffic index at that target location needs to be closely examined. The system can detect whether the level of the currently adjusted smooth traffic index is less than or equal to a preset second-level threshold. If the level of the adjusted smooth traffic index is detected to be greater than the second-level threshold, it is determined that the traffic facilities at the target location are reasonable under the smooth traffic index, and no adjustments to the current traffic facilities are necessary. If the level of the adjusted smooth traffic index is detected to be less than or equal to the second-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the smooth traffic index, and the smooth traffic level needs to be increased. Furthermore, according to the priority of each preset index, the system can further detect whether the level of the safety index is less than or equal to a preset first-level threshold. If the level of the safety index is detected to be greater than the second-level threshold, the system can further detect whether the level of the safety index is less than or equal to a preset first-level threshold. When the first-level threshold is mentioned, it is determined that the traffic facilities at the target location are reasonable under the safety indicators, and no adjustments to the current traffic facilities regarding safety indicators are needed. When the level of the safety indicator is detected to be less than or equal to the first-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the safety indicators, and the safety level needs to be increased. Furthermore, according to the priority of each preset indicator, the level of the convenience indicator is further detected to see if it is less than or equal to a preset third-level threshold. When the level of the convenience indicator is detected to be greater than the third-level threshold, it is determined that the traffic facilities at the target location are reasonable under the convenience indicators, and no adjustments to the current traffic facilities regarding convenience indicators are needed. When the level of the convenience indicator is detected to be less than or equal to the third-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the convenience indicators, and the convenience level needs to be increased.

[0130] In an exemplary embodiment of this application, for example, if a target location frequently experiences excessive pedestrian traffic and its convenience index continuously declines, it indicates that the convenience index at that target location needs to be closely examined. The system can detect whether the level of the currently adjusted convenience index is less than or equal to a preset third-level threshold. If the level of the adjusted convenience index is detected to be greater than the third-level threshold, it is determined that the traffic facilities at the target location are reasonable under the current convenience index, and no adjustments to the current traffic facilities are necessary. Conversely, if the level of the adjusted convenience index is detected to be less than or equal to the third-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the current convenience index, and the convenience level needs to be increased. Furthermore, according to the priority of each preset index, the system can further detect whether the level of the safety index is less than or equal to a preset first-level threshold. If the level of the safety index is detected to be greater than the preset first-level threshold, the system can further detect whether the level of the safety index is less than or equal to the preset first-level threshold. When the first-level threshold is mentioned, it is determined that the traffic facilities at the target location are reasonable under the safety indicators, and no adjustments to the current traffic facilities regarding safety indicators are needed. When the level of the safety indicator is detected to be less than or equal to the first-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the safety indicators, and the safety level needs to be increased. Furthermore, according to the priority of each preset indicator, the level of the smooth flow indicator is further detected to see if it is less than or equal to a preset second-level threshold. When the level of the smooth flow indicator is detected to be greater than the second-level threshold, it is determined that the traffic facilities at the target location are reasonable under the smooth flow indicator, and no adjustments to the current traffic facilities regarding smooth flow indicators are needed. When the level of the smooth flow indicator is detected to be less than or equal to the second-level threshold, it is determined that the traffic facilities at the target location are unreasonable under the smooth flow indicator, and the smooth flow level needs to be increased.

[0131] In an exemplary embodiment of this application, when the indicator levels under the safety indicator, smooth traffic indicator, and convenience indicator all drop significantly, the rationality of the traffic facility setting status at the target location can be judged in sequence from the three aspects of safety indicator, smooth traffic indicator, and convenience indicator according to a preset priority.

[0132] In an exemplary embodiment of this application, after adjusting the indicator level of the traffic facility setting status at the current target location under one or more preset indicators based on the traffic event occurrence obtained from real-time monitoring, if the final adjustment result shows that the level of each indicator quickly drops to the set level threshold, or the level of each indicator does not drop to the set level threshold for a long time, it indicates that the currently set level threshold is unreasonable, and the set level threshold can be adjusted, and adjustment suggestions can be given.

[0133] In an exemplary embodiment of this application, after judging the rationality of the traffic facility settings at each target location using the above-described scheme, if the settings are deemed unreasonable, the traffic facilities can be modified or adjusted according to the corresponding preset indicators. The modification can be based on the indicator levels of different traffic facilities under different preset indicators. In an exemplary embodiment of this application, the ranking of indicator levels of different traffic facilities under different preset indicators may include:

[0134] Regarding the aforementioned safety indicators, traffic facilities are ranked in descending order as follows: having an underpass / overpass, having a pedestrian crossing with traffic lights, having railings, having a pedestrian crossing without traffic lights, and having no traffic facilities.

[0135] For the aforementioned traffic flow index, traffic facilities are ranked in descending order as follows: underpass / overpass, railings, no traffic facilities, pedestrian crossings with traffic lights, and pedestrian crossings without traffic lights.

[0136] For the aforementioned convenience indicators, traffic facilities are ranked in descending order as follows: pedestrian crossings with traffic lights, pedestrian crossings with underpasses / overpasses, pedestrian crossings without traffic lights, no traffic facilities, and pedestrian crossings with railings.

[0137] In an exemplary embodiment of this application, for example, if a pedestrian crossing is provided at a target location, but the safety index level of the target location is lower than the first level threshold, the pedestrian crossing can be modified to improve the safety index level. For example, the pedestrian crossing can be modified into an underground passage or overpass with a higher safety level.

[0138] In an exemplary embodiment of this application, for example, if a railing is installed at a target location, but the accessibility index level of that target location is lower than the second level threshold, the railing can be modified to improve the accessibility index level. For example, the railing can be modified into an underground passage or overpass with a higher safety level.

[0139] In an exemplary embodiment of this application, for example, if a railing is provided at a target location, but the convenience index level of the target location is lower than the third level threshold, the railing can be modified to improve the convenience index level. For example, the railing can be modified into a traffic light pedestrian crossing with a higher safety level.

[0140] In the exemplary embodiment of this application, the target location to be analyzed is found by using the existing map data. Based on the occurrence of traffic events near the target location, a rationality analysis of the traffic facility setting status at the target location is performed from multiple preset indicators. It can promptly determine whether the traffic facilities at these target locations need to be warned and modified, and provide reasonable recommendations. This solves the current problem that it is impossible to make a scientific and reasonable judgment on whether a certain location needs to be equipped with traffic facilities and whether existing traffic facilities need to be modified, let alone make reasonable adjustments. It enables reasonable adjustments to traffic facilities, reduces the risk of traffic accidents, and significantly improves traffic safety, smoothness, and convenience.
