说明：  由于现有的地图匹配算法对算法的实时性和鲁棒性的研究相对较少，在提高地图匹配精 度的过程中对可用信息的利用不够，依据车辆运动的连续性，提出了基于计算几何的地图匹配算法。该算法能够快速的完成匹配候选道路的选取和匹配道路的确定。
(Existing map-matching algorithm for real-time and robustness of the algorithm is relatively small, the use of the available information is not enough in the process to improve the map matching accuracy, based on the continuity of the movement of the vehicle, based on computational geometrymap-matching algorithm. The algorithm can quickly complete the selection and matching to determine the road to match the candidate road.)
