LIU Lin①②,LI Wan-wu②,WANG Zhi-yu③,TIAN Yu②(① Wuhan University,Wuhan 430079,China;②Shandong University of Science and Technology,Shandong Qingdao 266510,China;③Huangdao Chinese Medicine Hospital,Shandong Qingdao 266510,China)  
The paper proposed the model of error triangle with the aid of the linear regression equations on the analysis of the error sources and the status of city roads,used the whole parallel moving matching method to weaken the system error;it analyzed the coordinates and heading angle of thousands of GPS positioning points,put forward the model of the relationship between the bidirectional traffic lane and GPS heading angle,which optimized the matching algorithm,weakened GPS random error and improved the speed and accuracy of map matching.
