城市道路中转弯情况下的拐点补传触发条件

Inflection Point Supplementary Transmission Trigger Condition in the Case of Turning in Urban Road

研究车辆行驶状况通常引入车辆轨迹回放,即车辆在行驶过程中所经过的路线,其包含了所走过的每一个GPS卫星数据点。然而,车辆行驶在城市道路中所面临的是弯道直路交错的复杂路况。因此,当行驶速度较快时,将出现一些弯道的轨迹被拉成直线的问题,影响研究数据。因此,需要在弯道和直路交叉变换等复杂路况拐点补传,论文针对城市道路弯道中的拐点补传触发条件进行研究。

Vehicle track playback is usually introduced to study vehicle driving conditions,that is,the route that the vehicle travels during the driving process,which contains each GPS satellite data point it travels.However,vehicles in urban roads are faced with a complex situation of straight and curved roads.Therefore,when the driving speed is fast,some curves will be drawn into a straight line,which will affect the research data.Therefore,it is necessary to carry out supplementary transmission at the inflection point in the complex road conditions,such as the intersection transformation of the curve and the straight road.This paper studies the triggering conditions of supplementary transmission at the inflection point in the urban road curves.
