Map Matching Based on GSM Positioning Data
Zhaocheng He · Journal of Transport Information and Safety · 2011
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 network connectivity.The field test network is selected from one segment from Guangzhou to Zhongshan.The map matching system can eliminate redundant data and analysis map matching result,which can validate this method's feasibility and effectiveness.
