The invention discloses a key vehicle track restoration method and system. The key vehicle track restoration method comprises the steps of obtaining a license plate and a color of a vehicle from an ETC door frame; obtaining static information from a high-speed intelligent management platform; obtaining dynamic information from the key operating vehicle dynamic information public exchange platform; vehicle tracks are updated regularly based on the key vehicle static information and dynamic information; the step of updating the key vehicle track comprises obtaining an actual pile number corresponding to the current time through a road pile coordinate table based on the longitude and latitude of the key vehicle; if the position of the key vehicle is not updated after the regular query time value, estimating an estimated stake number at the next moment based on the previous stake number, the real-time speed, the driving direction and the regular query time value; correcting the estimated stake number based on the actual stake number obtained at the next moment; and obtaining a key vehicle track based on the obtained stake number. The vehicle form track can be accurately given through combination of the static information and the dynamic information of the vehicle.
本发明公开了一种重点车辆轨迹还原方法及系统,包括从ETC门架获取车辆的车牌、颜色;从高速智慧管理平台获取静态信息;从重点营运车辆动态信息公共交换平台中获取动态信息;基于重点车辆静态信息和动态信息定期更新车辆轨迹;更新重点车辆轨迹包括:基于重点车辆经纬度,通过路桩坐标表获取当前时间对应的实际桩号;若经过定期查询时间值后,重点车辆位置未更新,则基于前一桩号、实时速度、行驶方向和定期查询时间值,估算下一刻的估算桩号;基于下一刻获得实际桩号对估算桩号进行修正;基于获得桩号获得重点车辆轨迹。本发明通过车辆静态信息和动态信息结合能准确给出车辆形式轨迹。
