Study on Map-matching Algorithm for simplified road network

The simplified road network has a simple structure and the algorithm running on it will be high efficiency,so it has a promoted effect on the basic research of map matching algorithm.This paper proposes a sequence-based bidirectional merge algorithm for map matching of GPS trajectoryin simplified road network.The experimental results show that the proposed algorithm in this paper not only have a well matching confidence,but also perform better than Passby algorithm and incremental algorithm,during the procedure of merging,the algorithm would address the problems of skipping segment and outliers.So,this algorithm has a better reference function for the map matching of the actual road network.
