Introduction

Abstract

In recent years, with the rapid economic development, the fact that the number of vehicles grows rapidly leads to the great demand for urban transportation management. Although many departments of urban transportation have strengthened the construction of road networks management and have improved the efficiency of transportation systems, the relationship between supply and demand for transportation has not been balanced and many necessary facilities are still in short of supply. Thus, this phenomena causes traffic congestion and makes people difficult to travel. Today, traffic congestion has become a serious problem faced by major cities of the world.
