The following describes aspects of the present disclosure in detail with reference to the accompanying drawings.

As shown in fig. 1, an application scenario of the road inspection method is shown, where the application scenario includes a server 110 and terminal devices 120, and in fig. 1, one terminal device 120 is taken as an example, and the number of terminal devices 120 is not limited in practice.

As shown in fig. 2, which is a schematic flow chart of the road inspection method of the present disclosure, the method may include the following steps:

Step 201: for any one target inspection road, acquiring a plurality of inspection parameters corresponding to a plurality of inspection tracks of the target inspection road, wherein the inspection parameters comprise inspection time, inspection speed and inspection position corresponding to the inspection time;

The inspection track includes various inspection positions, and an initial inspection position and a final inspection position, for example, as shown in fig. 3, the inspection track is an inspection track of the target inspection road, and the inspection track includes B, D, C, E, F, G, H, I, J, K, and M lands. Wherein each inspection position has corresponding inspection time and inspection speed. The site B is an initial inspection position, and the site M is a terminal inspection position. In this embodiment, the inspection parameters are recorded every 5 minutes, where the time interval for recording the inspection parameters can be set according to the specific practical situation, and the embodiment is not limited herein.

The inspection track in the embodiment is recorded in real time in the inspection road when driving.

Step 202: determining an average speed corresponding to any one of the patrol tracks in the target patrol road by utilizing a specified patrol position in patrol parameters corresponding to the patrol tracks and patrol time corresponding to the specified patrol position;

in one embodiment, the average speed corresponding to the patrol trajectory is determined by:

Obtaining a patrol total distance based on the initial patrol position and the final patrol position in each patrol position; and obtaining the total inspection duration by using the starting time corresponding to the starting inspection position and the end time corresponding to the end inspection position; and obtaining the average speed according to the total inspection distance and the total inspection duration. Wherein the average velocity can be determined by equation (1)

Wherein S _{Total (S)} is the total distance and t _{Total (S)} is the total length of the tour.

It should be noted that: the total inspection distance is obtained by subtracting the end inspection position and the initial inspection position, and the total inspection time is obtained by subtracting the end time and the initial time.

Step 203: determining the parking times corresponding to the inspection tracks based on the inspection speeds and the inspection time corresponding to the inspection speeds;

in one embodiment, the number of stops corresponding to the patrol trajectory is determined by:

Traversing each inspection speed in the inspection parameters corresponding to the inspection track according to the inspection time sequence; whenever it is determined that the traversed target patrol speed is within the first specified speed range, the following steps are performed:

determining each intermediate inspection speed corresponding to the target inspection speed, and obtaining the duration of the target inspection speed based on the largest inspection time in each inspection time of each intermediate inspection speed and the inspection time of the target inspection speed; the intermediate inspection speed is that the difference value between the inspection speed and the previous inspection speed is within a second designated speed range, and the inspection speed and the previous inspection speed of the inspection speed are both within the first designated speed range; if the duration of the target inspection speed is longer than the designated duration, adding a first designated threshold to the current parking times, and continuing to traverse the designated inspection speed as the target inspection speed until the traversing is finished, and determining the current parking times as parking times corresponding to the inspection track; the specified inspection speed is the inspection speed with the smallest inspection time among the inspection speeds after the intermediate inspection speeds.

For example, the specified duration is 3 minutes, and the inspection speed of the inspection parameters of the inspection track 1, which are arranged from large to small according to the time sequence, includes: speed 1, speed 2, speed 3, speed 4, speed 5, speed 6, and speed 7. And the current number of parks is 0, the first specified threshold is 1. And traversing from the speed 1, if the speed 1 is determined not to be in the first specified speed range, continuing to traverse the speed 2, and if the speed 2 is determined to be in the first specified speed range, determining that the intermediate inspection speeds are respectively the speed 3, the speed 4 and the speed 5. The inspection time corresponding to the speed 5 is the largest inspection time among the inspection times corresponding to the intermediate inspection speeds. If the difference between the maximum inspection time and the inspection time corresponding to the speed 2 is 4 minutes, the duration of the speed 2 is longer than the first appointed duration, and the current parking times are 1. Then the speed 6 is taken as the target inspection speed to continue the traversal. If none of the speeds 6 is within the first specified speed range, continuing to traverse the speed 7, and if it is determined that the speed 7 is not within the first specified speed range, ending the traversal. The current number of stops is 1. The number of stops corresponding to the patrol track is 1.

To avoid wasting resources, in one embodiment, before performing step 203, it is determined, for the patrol parameters corresponding to any patrol trajectory, that the patrol parameters do not include the number of parking times.

It should be noted that: if the inspection parameters corresponding to the inspection tracks comprise the parking times, the parking times can be directly used without secondary calculation of the parking times. The parking times in the inspection parameters are determined by the terminal equipment based on the real-time inspection speed and the duration time of the inspection speed in the inspection process.

Step 204: obtaining a target average speed and target parking times of the road through average speeds and parking times respectively corresponding to the plurality of inspection tracks; wherein the target average speed v _{Order of (A)} may be determined according to equation (2):

Wherein, among them, Is the average speed corresponding to the first patrol track,/>The average speed corresponding to the nth inspection track is equal to or greater than 1, and N is the total number of the inspection tracks.

The target number of parks P may be determined according to formula (3):

P＝p¹+…+p^m/M....(3)；

Wherein, p _m is the parking times corresponding to the mth inspection track, p ₁ is the parking times corresponding to the first inspection track, m is more than or equal to 1, and M is the total number of inspection tracks.

Step 205: obtaining the road inspection result according to the target average speed and the target parking times;

In one embodiment, the road patrol result is determined by:

If the target inspection average speed is determined to be greater than the first designated speed and the target inspection parking times are determined to be less than the second designated threshold, determining that the inspection result of the target inspection road is that the road is smooth; otherwise, determining that the road is not smooth as the inspection result of the target inspection road.

For example, the explanation will be given taking the first specified speed of 20km/h and the second specified threshold of 3 as an example. The following cases may be included:

Case one: and if the target average speed is 10km/h and the target inspection parking times are 4, determining that the target inspection average speed is smaller than the first designated speed, and the target inspection parking times are larger than the second designated threshold value, and determining that the road is not smooth.

And a second case: and if the target average speed is 30km/h and the target inspection parking times are 4 times, determining that the target inspection average speed is larger than the first designated speed, but the target inspection parking times are larger than the second designated threshold, and determining that the road is not smooth.

And a third case: and if the target average speed is 30km/h and the target inspection parking times are 2 times, determining that the target inspection average speed is larger than the first designated speed, and the target inspection parking times are smaller than the second designated threshold, and determining that the road is smooth.

Case four: and if the target average speed is 20km/h and the target inspection parking times are 2 times, determining that the target inspection average speed is smaller than the first designated speed, but the target inspection parking times are smaller than the second designated threshold, and determining that the road is not smooth.

Step 206: if the road inspection result is that the road is not smooth, determining a middle inspection parameter by utilizing inspection parameters corresponding to a plurality of inspection tracks of the road, wherein the middle inspection parameter comprises inspection average time corresponding to each inspection position;

Step 207: and determining a target signal lamp to be adjusted in the target inspection road based on the intermediate inspection parameter and a signal lamp display strategy in the target inspection road, and adjusting the display strategy of the target signal lamp.

In one embodiment, for any one of the intermediate inspection parameters, an average inspection time corresponding to the inspection position is obtained based on an average of the inspection times corresponding to the inspection position in each inspection track.

The signal lamp display strategy comprises the position of each signal lamp, the green light starting time of each signal lamp and the green light ending time of each signal lamp.

In one embodiment, as shown in fig. 4, to determine the target signal lamp and the adjustment mode of the corresponding display policy, the method may include the following steps:

Step 401: determining a target start time and a target end time corresponding to the signal lamps based on the inspection position in the intermediate inspection parameters and an average inspection time corresponding to the inspection position for any signal lamp in the target inspection road, wherein the target start time is a start time of passing an intersection corresponding to the signal lamps, the target end time is an end time of passing the intersection corresponding to the signal lamps, and the intersection corresponding to the signal lamps is determined based on the positions of the signal lamps;

And comparing each inspection position in the intermediate inspection parameters with the position of the signal lamp, if the difference value between the inspection position and the position of the signal lamp is within a first specified range, determining the average inspection time corresponding to the inspection position as a target starting time corresponding to the signal lamp, and if the difference value between the inspection position and the position of the signal lamp is within a second specified range, determining the average inspection time corresponding to the inspection position as a target ending time corresponding to the signal lamp.

For example, the intermediate patrol parameters include: [ patrol position 1, patrol average time A ], [ patrol position 2, patrol average time B ], [ patrol position 3, patrol average time C ]. If the difference between the inspection position 1 and the position of the signal lamp 1 is within the first specified range, determining the average inspection time A as the target starting time corresponding to the signal lamp 1. If the difference between the inspection position 2 and the position of the signal lamp 1 is within the second specified range, the inspection average time B is determined as the corresponding target ending time of the signal lamp 1.

Step 402; judging whether the target starting time is smaller than the current green light starting time of the signal lamp, wherein the current green light starting time is the green light starting time with the shortest time interval with the target starting time, if so, executing step 403, and if not, executing step 404;

Step 403: advancing the green light starting time of the target signal lamp by a first designated time length, wherein the first designated time length is determined according to the target starting time and the current green light starting time;

Step 404: and judging whether the target ending time is greater than the current green light ending time of the signal lamp, wherein the current ending time is the green light ending time with the shortest time interval with the target ending time, if so, executing step 405, and if not, ending.

For example, the green light start time with signal light 1 includes: 10:00, 10:08, 10:16, 10:24, etc., the green light end time of signal 1 includes: 10:02, 10:10, 10:18, 10:26, etc., if the target start time of the signal lamp 1 is 10:01 and the target end time is 10:03, since the time interval between the green light start time 10:00 and the target start time is shortest, the green light start time 10:00 is determined as the current green light start time of the signal lamp 1, and since the time interval between the green light end time 10:02 and the target end time is shortest, the green light end time 10:02 is determined as the current green light end time of the signal lamp 1. From this, it can be seen that the target start time is greater than the current green light start time, but the target end time is also greater than the current green light end time, and it is determined that the signal lamp 1 is the target signal lamp.

Step 405: and determining the signal lamp as the target signal lamp, and delaying the green light starting time of the target signal lamp by a second designated time length, wherein the second designated time length is determined according to the target ending time and the current green light ending time.

The green light start time and the green light end time of the signal lights corresponding to the intersections can be represented by using a time-distance graph, as shown in fig. 5, the transverse coordinates of the time-distance graph represent positions, and the longitudinal coordinates represent time. The gray area in the figure indicates the time of the green light of the signal light at each intersection. Wherein, road segment 1 represents a road segment between intersection 1 and intersection 2, road segment 2 represents a road segment between intersection 2 and intersection 3, and road segment 3 represents a road segment between intersection 3 and intersection N. The intermediate inspection track can be determined according to the intermediate inspection parameters determined in the foregoing. The comparison of the intermediate inspection track and the time interval graph has three forms in the graph:

form one: when the position of the middle inspection track in the time interval diagram is within the green time of the signal lamp, the signal lamp is determined to be not required to be adjusted if the vehicle just passes through the intersection. As shown in fig. 5, the middle inspection track corresponding to the intersection 1 and the intersection N is within the green time of the signal lamp corresponding to the intersection, so that the vehicle passes through the intersection in the right green time.

Form two: when the position of the middle inspection track in the time interval diagram is above the green light time of the signal light, and the green light time of the signal light of the intersection is finished after the vehicle arrives at the intersection, the signal light is determined to be the target signal light to be adjusted if the next green light time needs to be waited (namely, the target ending time is longer than the current green light ending time of the signal light). As shown in fig. 5, the position of the corresponding intermediate patrol track in the intersection 2 in the time-distance diagram is above the green time of the signal lamp, and then the position indicates when the vehicle passes through the intersection 2. The green light of the signal light at the intersection has ended.

Form three: when the position of the middle inspection track in the time-distance diagram is below the green light time of the signal light, the green light of the signal light is not released when the vehicle arrives at the intersection, and a period of waiting time is needed (namely, the target starting time is smaller than the current green light starting time of the signal light). The signal is determined to be the target signal that needs to be adjusted. As shown in fig. 5, the position of the middle patrol track in intersection 3 in the time distance graph is below the green time of the signal lamp, indicating that the green light of the signal lamp has not yet started.

For further understanding of the technical solution of the present disclosure, the following detailed description with reference to fig. 6 may include the following steps:

step 601: for any one target inspection road, acquiring a plurality of inspection parameters corresponding to a plurality of inspection tracks of the target inspection road, wherein the inspection parameters comprise inspection time, inspection speed and inspection position corresponding to the inspection time;

Step 602: obtaining a patrol total distance based on the initial patrol position and the final patrol position in each patrol position; obtaining the total inspection duration by using the starting time corresponding to the starting inspection position and the end time corresponding to the end inspection position;

Step 604: determining the parking times corresponding to the inspection tracks based on the inspection speeds and the inspection time corresponding to the inspection speeds;

step 605: obtaining a target average speed and target parking times of the road through average speeds and parking times respectively corresponding to the plurality of inspection tracks;

Step 606: judging whether the target inspection average speed is greater than a first designated speed and whether the inspection parking times are less than a second designated threshold, if so, executing step 607, otherwise, executing step 608;
