Abstract: Intelligent Transportation System (ITS) has become the inevitable trend and the main ways to improve the efficiency of road network traffic. However, ITS application in traffic is influenced by many factors, which discounted the benefit to a great extent. Therefore, how to refine the optimization scheme of ITS on transport efficiency is a major task that the urban traffic faced, according to the actual needs of urban traffic. Through analyzing, the optimization goal and influencing factors are firstly cleared. Then the passenger person-kilometer of different traffic modes is selected as the main indicator. Moreover, the multi-objective planning method is selected and the MOP model of ITS to urban road network traffic efficiency is built. Furthermore, Beijing is selected as an example for empirical study. Research results show that the application of ITS is the support of different transportation to achieve the expected goal. Then the transportation turnover is put forward to ensure the optimal efficiency of network operation.
