Vehicular cooperative map matching

In this paper a novel Vehicular cooperative map matching method is presented. This map matching method uses the V2V communication in a VANET to exchange GPS information between vehicles. Then vehicles can apply the road constraints of other vehicles in their own map matching process and acquire a significant improvement in their positioning. The dependency of GPS measurements between different vehicles, which can lead to an over converged positioning result has been considered and circumvented in our method. The performance of the proposed algorithm has been verified with simulations in several realistic scenarios.
