Abstract :
This paper describes a method using grid technology to improve traffic algorithm efficiency. The method cooperates traffic status estimation algorithm with grid technology. It collects and preprocesses massive real-time data of taxi global positioning system (GPS) as floating car data as well as geographic Information systems (GIS) data of Shanghai urban road network. Then, it adopts grid technology to deal with computation for the shortest time path algorithm on traffic status estimation in real time. The results of experiment prove that the grid technology can greatly improve the computing efficiency of traffic status estimation model.
