车辆配送路径轨迹弧长偏差可视化校正仿真

Visual Correction Simulation of Vehicle Distribution Path Arc Length Deviation

由于车辆配送路径轨迹偏差会延长货品配送时间,影响物流服务质量。针对传统配送路径轨迹偏差校正方法校正性能不足的问题,提出一种基于GPS和地图匹配的车辆配送路径轨迹弧长偏差可视化校正方法。利用GPS定位目标物流车辆当前所在位置,并将所得到的位置信息显示在电子地图上;将电子地图上所显示的路径轨迹与规划的地图道路进行匹配,确定偏差范围;根据偏差范围,进行路径偏差校正。实验结果表明,与三种传统配送路径轨迹偏差校正方法相比,利用所提方法进行车辆配送路径轨迹弧长偏差可视化校正,得到的校正路径与规划路径之间的拟合优度更接近1,且车辆配送效率较高,由此说明该方法校正性能更强。

The deviation of vehicle distribution path will prolong the distribution time and influence the quality of logistics service.In this context,a visualizing correction method of arc length deviation of vehicle distribution path trajectory based on GPS and map matching was put forward.This method contained three parts.In the first part,the current position of target logistics vehicle was located by GPS,and the position information was displayed on the electronic map.In the second part,the path trajectory shown on electronic map was matched with the planned road in map to determine the deviation range.In the third part,the path deviation was corrected by the deviation range.Simulation results show that,compared with the three traditional methods,when the proposed method is used to visually correct the arc length deviation of vehicle distribution path trajectory,and the goodness of fit between the corrected path and the planned path is closer to one.Meanwhile,the vehicle distribution efficiency is higher and the correction performance is stronger.
