摘　　要：提出了一种复杂度低、实时性好、匹配准确率高的综合地图匹配方法。该方法综合基于权重度量值和曲线拟合的地图匹配思想,并结合路网拓扑信息,提供实时准确的车辆位置信息,可应用于车辆监控、实时交通信息采集、车辆导航。还提出了车辆位置相关的弧投影算法和GPS信号无效时的航位推算算法。This paper presented a map matching method with lower complexity, better real-time and higher matching ac- curacy. The method, which is based on the weights measure and curve fitting map match ideology, and combined with road network topology information, provides vehicle location information timely and accurately, and can be applied to the vehicle monitoring, real-time traffic information collection, vehicle navigation. The paper also proposed the are-projection algorithm with vehicle position- dependent and the dead reckoning algorithm used when the GPS signal is not valid.
