A Fuzzy Logic Map Matching Algorithm

Many Intelligent Transportation System applications require continuous and accurate positioning information of the vehicles traveling on the road network. The common devices used for vehicle location are based on Global Position System (GPS), dead-reckoning (DR) sensors, map matching (MM). The paper develops a fuzzy logic based map matching algorithm. The algorithm is tested on different road networks of varying complexity. The results show that the fuzzy logic based map matching algorithm provides a significant improvement over existing map matching algorithms both in terms of identifying correct links and estimating the vehicle position on the links.
