Map matching is the process which work for location measurement and also find out appropriate route for smooth traveling on the road network, but map matching accuracy fully depends on GPS trajectory data and electronic map of the road network. Unfortunately, GPS data is not accurate because, it's through weak GPS signaling and low quality GPS devices. So, it is difficult to calculate accurate location of movements.This work provides, a map mapping algorithm for simplifying appropriate path, including curves on road network and also, we proposed Frechet distance computing algorithm with road Preliminaries for network simplification.
