The invention discloses a vehicle attendance checking algorithm using the data of spatial trajectories and a road network. The vehicle attendance checking algorithm comprises the step of: A, preparing vehicle trajectory data including vehicle basic information and vehicle positioning information, preparing urban road network basic data including road link data and vehicle road network speculation matching trajectories, speculating a vehicle trajectory GPS point sequence, matching the GPS points to the closest link, returning the coordinates of a perpendicular foot point, and matching the coordinates to the shape of the link to generate a trajectory diagram. With the method adopted, if the conditions of vehicle overspeeding, overlong time stay, mismatching of driving routes and the like occur, early warning can be performed to prompt a driver and a monitoring station, the driver can correct driving in time conveniently. The method can analyze the regional overlapping property of vehicle driving every day and the effectiveness of driving patrol, and provides a basis for vehicle patrol attendance check. The problems of failure to calculate the effective patrol duration of a vehicle and deal with emergency state early warning in a vehicle patrol process can be solved.

    本发明公开了利用空间轨迹与路网的数据的车辆考勤算法,其考勤算法包括以下步骤:A:准备的车辆轨迹数据,包含车辆基本信息、车辆定位信息,准备城市路网基础数据,包含道路link数据,车辆路网推测匹配轨迹,将车辆轨迹GPS点序列进行推测,将GPS点匹配到距离最近到link上,返回垂足点坐标,将坐标匹配到link形状生成轨迹图。本发明如出现车辆超速、停留时间过长和行车线路不匹配等情况,可以进行预警提示驾驶员和监控站点,便于驾驶员及时修正驾驶,具备可以分析车辆每天行驶的区域重叠性、驾驶巡逻的有效性,为车辆巡逻考勤提供依据的优点,解决了在车辆巡逻过程中,无法统计车辆有效巡逻时长,以及无法对应紧急状态预警的问题。
