The vehicle trajectory extraction algorithm based on license plate recognition data,in order to extract the travel trajectory of all vehicles running on the urban road network,systematically reproduce the operation of all vehicles scene,and provide data support for analyzing the structure and spatial and temporal distribution characteristics of urban traffic demand.The travel chain through the license plate and timestamp was sorted out;The separation of the travel chain was accomplished by using the velocity between adjacent nodes and the intersection matrix;The travel trajectory based on K shortest path algorithm(KSP algorithm)and Gray relational analysis(GRA algorithm)was completed.The algorithm was tested based on the actual license plate identification data of Nan-ming District,Guiyang City,Results show that the algorithm based on the license plate recognition data is more than 92%in the test area.
