標題: | Novel traffic signal timing adjustment strategy based on Genetic Algorithm | 作者: | TIAN-LI YU | 公開日期: | 2014 | 起(迄)頁: | 2353-2360 | 來源出版物: | Proceedings of the 2014 IEEE Congress on Evolutionary Computation, CEC 2014 | 摘要: | Traffic signal timing optimization problem aims at alleviating traffic congestion and shortening the average traffic time. However, most existing research considered only the information of one or few intersections at a time. Those local optimization methods may experience a decrease in performance when facing large-scale traffic networks. In this paper, we propose a cellular automaton traffic simulation system and conduct tests on two different optimization schemes. We use Genetic Algorithm (GA) for global optimization and Expectation Maximization (EM) as well as car flow for local optimization. Empirical results show that the GA method outperforms the EM method. Then, we use linear regression to learn from the global optimal solution obtained by GA and propose a new adjustment strategy that outperforms recent optimization methods. © 2014 IEEE. |
