One New Map Matching Model for Vehicle-Borne Navigation System

The technique of vehicle-borne navigation system develops rapidly. Map matching is one of the key techniques of the vehicle-borne navigation. General map matching method is based on simple point projection. It often appears matching errors in the face of complicated roadways. The article aims at the shortcoming of general map matching, and designs a forecast map matching model based on roadway topology and geometry characteristic. What´s more, the model is validated by practical running tests. Forecast map matching model brings new idea in order to resolve the difficult problem of matching on complicated roadways.
