The Research on Real-Time Map-Matching Algorithm

This paper presents a compatible map-matching algorithm for intersection: multi-weight probability of real-time map-matching algorithm. The map-matching algorithm divides in three different stages: the initial matching stage, the cross region matching stage, the determining location stage in the matching road. The algorithm takes different procedures for the three stages to improve the matching and displaying accuracy. The results of simulation in Matlab platform show that comparing with the present existing algorithms. The multi-algorithm does not introduce complex operations, but significantly reduces the matching errors of vehicles along road directions and the probability of wrong matching junction regions. Meanwhile, it helps to improve the display for intersection region matching.
