城市道路交叉口信号配时多目标优化方法研究
Multi-objective optimization method for signal timing of urban traffic intersection
摘要
Abstract
To solve the problems of single optimization objective and low efficiency in signal timing,a novel multi⁃objective optimization method for signal timing of intersections is proposed. In consideration of constraint conditions of green⁃light dura⁃tion,cycle length and saturability,the cost function is defined by weighted coefficient method to make delay time,parking times and traffic capacity of intersections optimum to some extent. Based on the characteristics of uniformity and wide⁃distribu⁃tion of optimal solution while immune clone algorithm(ICA)is used to solve multi⁃objective problems,a new environment muta⁃tion operator was introduced,and the environment mutation ICA was proposed for model solution,which enhanced the global searching ability of the algorithm and improved the solution quality. The simulation results reveal that,compared with the tradi⁃tional timing method and inertia weight particle swarm algorithm,the presented method can efficiently reduce average delay, parking times of intersections,and improve the efficiency of traffic signal control.关键词
