In an exemplary embodiment of the present application, for example, the smoothness index may be measured by a congestion condition, the congestion condition may be mainly determined according to a smoothness degree of the vehicle and/or the pedestrian, for example, the vehicle congestion occurs in the early and late peak, the base of the smoothness index may be deducted by 2 points, and the congestion occurs in the off-peak period in normal times may be deducted by 5 points; the congestion period exceeds 50% in one period, and a further 10 minutes is deducted.

In an exemplary embodiment of the present application, for example, for convenience metrics, pedestrian traffic may be measured by: 1. according to the people flow rate camera capturing, deducting a convenient index for 2 minutes after the people flow rate value exceeds a threshold value; 2. confirming the number of people passing between two points through face snapshot, and deducting 2 points after the number of people exceeds a certain number threshold; 3. the condition that whether the illegal crossing of the road exists or not is obtained through the camera and the operation data of the bus taxi, and the condition can be deducted by 5 points if the condition exists.

In the exemplary embodiment of the present application, for example, if traffic jam occurs frequently at a certain target location and the smoothness level is continuously decreased, it is explained that the smoothness index at the target location needs to be considered with emphasis, whether the index level of the smoothness index after current adjustment is smaller than or equal to a preset second level threshold value may be detected, and when it is detected that the index level of the smoothness index after adjustment is greater than the second level threshold value, it is determined that the traffic facility set at the target location is reasonable under the smoothness index, and the smoothness index of the current traffic facility may not be trimmed; when the index level of the regulated unblocked index is detected to be smaller than or equal to the second level threshold, judging that the traffic facilities arranged at the target position are unreasonable under the unblocked index, and according to the priority of each preset index, further detecting whether the index level of the safety index is smaller than or equal to the preset first level threshold or not, and when the index level of the safety index is detected to be larger than the first level threshold, judging that the traffic facilities arranged at the target position are reasonable under the safety index, and not finishing the safety index aspect of the current traffic facilities; when the index level of the safety index is detected to be smaller than or equal to the first level threshold, judging that the traffic facility arranged at the target position is unreasonable under the safety index, and the safety level needs to be improved, and further detecting whether the index level of a convenient index is smaller than or equal to a preset third level threshold according to the priority of each preset index, and when the index level of the convenient index is detected to be larger than the third level threshold, judging that the traffic facility arranged at the target position is reasonable under the convenient index, and not finishing the current traffic facility in the aspect of convenient index; when the index level of the convenient index is detected to be smaller than or equal to the third level threshold, judging that the traffic facilities arranged at the target position are unreasonable under the convenient index, and improving the convenient level is needed.

In the exemplary embodiment of the present application, for example, if the traffic volume is too large at a certain target location and the convenience index is continuously decreased, it is explained that the convenience index at the target location needs to be considered with emphasis, whether the index level of the current adjusted convenience index is smaller than or equal to a preset third level threshold value can be detected, and when it is detected that the index level of the adjusted convenience index is greater than the third level threshold value, it is determined that the traffic facility set at the target location is reasonable under the convenience index, and the current traffic facility can not be trimmed in terms of the convenience index; when the index level of the adjusted convenient index is detected to be smaller than or equal to the third level threshold, judging that the traffic facilities arranged at the target position are unreasonable under the convenient index, and according to the priority of each preset index, further detecting whether the index level of the safety index is smaller than or equal to the preset first level threshold, and when the index level of the safety index is detected to be larger than the first level threshold, judging that the traffic facilities arranged at the target position are reasonable under the safety index, and not finishing the safety index aspect of the current traffic facilities; when the index level of the safety index is detected to be smaller than or equal to the first level threshold, judging that the traffic facility arranged at the target position is unreasonable under the safety index, and the safety level needs to be improved, and further detecting whether the index level of the unblocked index is smaller than or equal to a preset second level threshold according to the priority of each preset index, and when the index level of the unblocked index is detected to be larger than the second level threshold, judging that the traffic facility arranged at the target position is reasonable under the unblocked index, and not finishing the unblocked index aspect of the current traffic facility; when the index level of the unblocked index is detected to be smaller than or equal to the second level threshold, judging that the traffic facilities arranged at the target position are unreasonable under the unblocked index, and improving the unblocked level is needed.

In the exemplary embodiment of the application, when the index level of the safety index, the smoothness index and the convenience index are greatly reduced, the rationality of the traffic facility setting state of the target position can be judged in sequence from the three aspects of the safety index, the smoothness index and the convenience index according to the preset priority.

In the exemplary embodiment of the present application, after the traffic facility setting state of the current target position is adjusted according to the traffic event occurrence condition obtained by real-time monitoring, if the level of each index is found to be quickly reduced to the set level threshold value according to the final adjustment result, or the level of each index is not reduced to the set level threshold value for a long time, it is indicated that the current set level threshold value is unreasonable, the set level threshold value may be adjusted, and an adjustment suggestion may be given.

In the exemplary embodiment of the present application, after the rationality of the traffic facility setting state of each target location is determined by the above scheme, the set traffic facilities may be modified and adjusted from the corresponding preset indexes when the determination is unreasonable, and the modification may be performed according to the index levels of different traffic facilities under different preset indexes. In an exemplary embodiment of the present application, the index rank ordering of different traffic facilities under different preset indexes may include:

For the safety indexes, the traffic facilities rank-order the indexes in the order from high to low as follows: the road is provided with an underground passage/an overpass, a traffic light crosswalk, a railing, a non-traffic light crosswalk and no traffic facilities;

for the unblocked index, the traffic facilities rank-order the indexes in the order from high to low as follows: the underground passage/overpass, the railing, the traffic facilities, the traffic light crosswalk and the non-traffic light crosswalk are arranged;

for the convenient index, the traffic facilities rank-order the indexes in the order from high to low as follows: the road is provided with a traffic light crosswalk, an underground passage/an overpass, a non-traffic light crosswalk, no traffic facilities and railings.

In an exemplary embodiment of the present application, for example, if a crosswalk is currently set at a certain target location, but the index level of the safety index of the target location is lower than the first level threshold, the crosswalk may be considered to be modified to improve the index level of the safety index, for example, the crosswalk may be modified to a higher safety level underground passage or overpass.

In an exemplary embodiment of the present application, for example, if a balustrade is provided at a certain current target location, but the index level of the unblocked index of the target location is below the second level threshold, it may be considered to reform the balustrade to increase the index level of the unblocked index, for example, the balustrade may be reformed into a higher security level underground passage or overpass.

In an exemplary embodiment of the present application, for example, if a railing is provided at a current certain target location, but the index level of the convenience index of the target location is lower than the third level threshold, the railing may be considered to be modified to improve the index level of the convenience index, for example, the railing may be modified to a traffic light crosswalk with a higher safety level.

In the exemplary embodiment of the application, the target position to be analyzed is found through the original data of the map, the rationality analysis is carried out on the traffic facility setting state at the target position from a plurality of preset indexes aiming at the traffic event occurrence condition near the analysis target position, whether the traffic facilities at the target position need early warning modification or not can be timely known, and reasonable recommendation is given, so that the problems that whether the traffic facilities need to be set at a certain position at present or not, whether the existing traffic facilities need to be modified or not can not be scientifically and reasonably judged, and reasonable adjustment can not be given are solved, the rationality adjustment can be carried out on the traffic facilities, the traffic accident hidden danger is reduced, and the traffic safety, smoothness and convenience are greatly improved.
