| Abstract: | This paper discusses the problem of the GPS real time information locating on the digital map in the vehicle guidance system. Analyzing the factors caused by deviation of GPS and complexity of road network which leads to the inaccurate of direct location. A map-matching method based on the GPS real time information is presented, which considers the similarity between the tracks of GPS points and road network, also uses the GPS real time information of the vehicle ,such as navigation, the method improves the accurate of location. |
