Abstract:

A map-matching algorithm can be used as a key component to improve tne perlormance of systems that napport the navigation function of intelligent tran sport systems （ITS）,anti it plays an important role in vehicle locating and navigation systems. This paper presents a fuzzy-logic-based map matching a  algorithm, The inputs to the algorithm normally come from the GPS/DR sensor and digital map data, and through fuzzy judgment,the algorithm outputs the best section of the matched road,and selects the candidate roads at the junction. The results of  experimental simulations show that the map matching eff iciency and accuracy increase greatly after introducing this algorithn
