基于手机基站定位数据的地图匹配研究

研究如何利用手机基站定位数据信息进行地图匹配,其基本原理是通过采集车载手机通过道路的基站切换序列,在剔除冗余数据后,利用初始蜂窝小区定位算法实现每一个切换点在电子地图上的匹配,再利用路网的连通性实现路径的匹配。选取广州市到中山古镇路段作为实验路网进行实地实验,对所获得的基站信息进行数据处理和地图匹配的结果进行分析,证明通过手机基站定位数据来进行地图匹配的可行性和有效性。

Map Matching Based on GSM Positioning Data

The application of cell phone location technology for traffic data collection has been hot recently and the map matching is one of the key points.The emphasis of this paper is placed on how to use GSM position data for map matching.The basic principle is to collect the switching sequences of base stations by which vehicle-mounted mobiles pass,and then to use cell of origin positioning algorithm to position each switching point of the sequence after data processing.The path matching is achieved based on road...
