Study Of The Impact Of Bus Stops On Adjacent Non-Motorized Lanes Based On Target Detection Algorithm

In recent years,with the rapid improvement of China’s economic level,the increase of the number of motor vehicles and the increasing congestion of urban traffic,non-motor vehicles such as electric bicycles have become important means of transportation for residents.However,in the bus station area,the riding continuity of non-motor vehicles is poor and the safety is low.In order to reduce the interference of the station to the non-motor vehicle lane,many bus stations choose to build on the inner side of the motor vehicle lane,and the physical isolation is often used between the nonmotor vehicle lane and the motor vehicle lane.However,there are still potential safety hazards that can not be ignored.The geometric structure of the bus station and the boarding and alighting passengers crossing the non-motorized Lane will affect the riding behavior of non-motorized vehicles,resulting in traffic conflicts and accidents.Therefore,studying the micro behavior of non-motor riders near bus stops and revealing the specific effects of bus stop length,non-motor lane width and number of entrances and exits on riding preference and riding speed are conducive to improving the safety of non-motor riding,improving the order of mixed traffic flow and optimizing traffic operation management.Firstly,according to the field investigation of the selection standard of bus stations,this paper uses the control variable method to group all bus stations according to three different indicators:the road width of non-motor lanes,the number of entrances and exits and the length of stations,and takes videos of non-motor vehicles near bus stations in the morning and evening peak hours;Secondly,train the non-motor vehicle data set,identify the non-motor vehicle by using yolo-v5 target detection algorithm,extract the non-motor vehicle flow and speed,and analyze the influence of platform length,nonmotor vehicle lane width and the number of entrances and exits on the riding track and speed of adjacent non motor vehicles one by one;Finally,according to the impact of bus station geometry and road conditions on non-motor Lane conflict,a mathematical model is established to evaluate Lane riding safety.In terms of riding preference,the width of non-motor Lane mainly affects the lateral riding preference;The length of bus stop mainly affects the longitudinal riding preference;The number of entrances and exits will have an impact on the horizontal and vertical riding preference.In terms of the impact of riding speed,the wider the lane,the faster the non-motor speed in the platform area;The longer the platform,the faster the downstream speed of the platform increases,and the speed gap between the left,middle and right areas of the lane increases;The more entrances and exits,the slower the non-motor speed in the platform area.In addition,compared with open entrances and exits,closed entrances and exits have a greater impact on platform riding speed and riding preference,and significantly affect Lane riding safety.
