摘　　要：地图匹配技术作为新一代智能交通系统中车辆导航方面的核心技术,提高其匹配效率,是有效提供车辆诱导,优化公众出行,精准交通服务信息的重要改进手段。本文针对高速公路上营运车辆的GPS信息,结合我国高速公路路网特点,重点研究了基于浮动车技术的高速公路地图匹配算法,通过引入距离判据、方向角判据及连通性判据进行地图匹配,并根据实例验证中的路网匹配情况对算法进行改进,使得匹配算法具有更强的适应性和更高的实效性。Map- matching technology is the core technology in the field of vehicle navigation of the new generation of intelligent transportation system,and that improve the match efficiency of it is an important means to induce vehicle effectively,to optimize public transportation,to accurate traffic information. Regarding to the GPS information for operating vehicles on the highway,this paper presents a highway mapmatching method which is based on floating technology. To improve the point-line matching model of traditional map-matching model by introducing distance criterion,the direction angle criterion and connectivity criterion,and verify the effectiveness through the actual highway data. And to improve the algorithm in accordance with the matching condition of highway network of example validation,so as to construct an algorithm model which is more efficient,more accurate,more suitable for highway and based on floating car map-matching,making the matching algorithm of stronger adaptability and higher effectiveness.
