摘要
考虑到实际路况下的车辆行驶方向的信息、电子地图道路层的网络拓扑结构信息、车辆的历史轨迹信息对地图匹配重要性,提出的地图匹配算法包括三个部分:对定位数据的预处理;待匹配道路的识别;定位点的投影匹配。通过实验仿真,该算法具有较高的鲁棒性,符合高精度、低成本的发展要求。
Taking into accounts the importance of vehicle traveling in formation, the network topology information of the electronic map layer and vehicle＇s historical track information to map-matching an algorithm of map-matching is proposed. It includes three parts： pre-processing of positioning data; identification of roads to be matched; matching of the point projection. Through the experimental simulation, the algorithm has higher robustness, and meets with the requirements of high-precision and low-costs.
