A Fuzzy-Logic-Based Map Matching Algorithm for the GPS/DR System
Zhang Yong-jie · Computer Engineering and Science · 2008
A map-matching algorithm can be used as a key component to improve the performance of systems that support the navigation function of intelligent transport systems(ITS),and it plays an important role in vehicle locating and navigation systems.This paper presents a fuzzy-logic-based map matching 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 efficiency and accuracy increase greatly after introducing this algorithm.
