An improved map matching algorithm for intelligent transportation system

In the paper, an algorithm is put forward based on fuzzy logic for real-time matching of GPS positioning results, which is integrated with DR in intelligent transportation system. Besides, at junctions this algorithm makes use of road network topological structure and the continuity of vehicles' track to choose the continuing route with maximum possibility as a matched result from multiple candidates. The algorithm can be widely used as its computation is easy and the matching result is more accurate.
