The invention provides a real-time bus arrival prediction method based on route tracks, and aims to calculate the prediction time from a bus to a current station by combining conditions such as routenetwork data, Gps real-time data and historical driving speed, solve the problem that an electronic station board only displays the number of distance stations and does not display the distance time,and improve the use satisfaction of the public. The real-time bus arrival prediction method mainly comprises N steps of: firstly, generating a track sequence set according to bus network data; secondly, calculating an average running speed of vehicles in different time periods of different routes after the historical running Gps of the vehicles are classified and summarized; and loading real-timeGps vehicle-mounted terminal data, taking the routes as a classification condition to obtain all vehicles under the route, and calculating the arrival time and the number of distance stations and thelike between the vehicles and front and rear stations according to the road network track set of the current route, real-time gps projection positions of the vehicles, the projection position of eachstation of the route, a predicted running speed per hour of the route and other conditions. The real-time bus arrival prediction method is suitable for measuring and calculating the arrival time of the public transport vehicles.
本发明提供一种基于线路轨迹的实时公交到站预测方法,目的是通过结合线网数据、Gps实时数据,历史行驶速度等条件计算出公交车距离当前站点预测时间,解决电子站牌只显示距离站数,不显示距离时间的问题,提升大众的使用满意度。本发明主要包括N个步骤,首先根据公交线网数据生成一个轨迹序列集合;然后根据车辆历史运行Gps分类汇总后计算出车辆在不同线路的不同时间段的运行平均速度;加载实时Gps车载终端数据,以线路作为分类条件,得到线路下的所有车辆,根据当前线路的路网轨迹集合,车辆实时gps投影位置、线路各站点投影位置,线路预测运行时速等条件,计算车辆距离前后站点的到达时间和距离站数等。本发明适用于公交车辆到达时间的测算。
