| At present, transportation of our large metropolitan is getting more and more congested, development of bus service can make more travelers utilize freeing up space on our streets and alleviate congestion. It is the chef subject that how to enhance the operating efficiency of bus system to provide quick and comfortable service. Therefore, the objective of this study is the development of new method of Bus priority, and the VISSIM software is used to simulate and analyze signal controls method. Concrete work including several following aspects:1. The basic theory of bus priority was Elaborate and summed up the commonly active bus priority control method, as a theoretical basis for this study.2. Single intersection traffic control are designed base on the adaptive signal control method, including Green Extension, Red Truncation, Special Phase and computational method of related parameters, and partial indented were proposed at approach saturated signal intersection.3. Based on the signal control of the isolated intersection, a dynamic optimization and control method for urban artery is presented, whose objective is to maximize the throughput of artery system during the whole control period. The dynamic optimization model which adopt cycle length, split as the decision variables is established and proposes the modified optimal algorithm of urban arterial traffic signal coordination control and use genetic algorithms to solve the model4. Base on actual survey data, using the the process of the micro-simulation simulate the traffic situation. Through evaluating different control method results, the efficiency of the proposed control method is analyzed.
