| 摘 要： | 地图匹配算法对于车辆路径诱导和实时轨迹回放具有重要的应用,为了提供连续、精确和可靠的车辆行驶路段位置,利用定位传感器输出车辆运行位置信息,结合高精度空间道路网络数据,提出新的综合地图匹配算法.该算法不受地理环境的约束,能有效地修正传感器的定位误差,提高车辆定位精度.实际道路测试证明,该算法比现有地图算法更高准确度和实时性,尤其是在十字路口有更好匹配效果.

| Abstract: | The map-matching algorithm plays an important role in monitoring timely vehicle movement track and routing guidance.For getting continuous,accurate and reliable vehicle location on a given road segment,the new algorithm is proposed by integrating GPS data,dead reckoning data,and spatial digital database of the road network.It is irrespective of the constraints imposed by the operational environment,and improves effectively stand-alone positioning sensor error.The map-matching algorithm has been tested using real field data and has been found to be superior to existing algorithms,particularly in how it performs at road intersections. |
