英文摘要：

Based on the design principle of minimum arterial road delay time and maximum link travel speed,an urban roads traffic signal control method of bi-level programming model was established by using intelligent optimization algorithms and group decision making theory.The algorithm which combined the genetic algorithm of intelligent optimization strategy and the advice of a rich group of experts was designed,a description of fuzzy number was set up to realize analysis evaluation of different control targets,and the whole optimum proposal for traffic signal timing of arterial roads was given,thus,the analysis of traffic problem was made more objective and practical.Finally,an example of signal control time optimization for a real arterial road was analyzed,and hybrid programming calculation with MATLAB and Visual C＋＋ was introduced to simulate the control scheme.The result shows that the method can effectively minimize delay and maximize link travel speed.
