摘要
随着汽车与交通事业的快速发展,城市交通问题日益突出,而增加道路和限制车辆已不是解决问题最经济有效的办法。如何在现有交通设施的条件下解决交通问题才是需要考虑的。作为整个交通网络最小研究单元的单个交叉路口,它的控制方法的研究是基础,但是却无法反映其他路口的控制对它产生的影响,即无法反映路口间的耦合关系,所以主要讨论两个交叉路口交通的控制。建立了两路口交通的优化模型,给出了目标函数以及约束条件,采用遗传算法进行优化,开发出了两交叉路口的交通灯控制仿真软件,得到了较好的效果。
With the rapid development of automobile and traffic management, the heavy traffic problem becomes more and more serious, and the solution by increasing new road and constraining the vehicle is not the most economical and effective measures. How to solve traffic problems in existing condition is worth considering. As the basic unit of the whole traffic network, studding on the traffic control method of isolated intersection is the foundation. But it could not reflect the infection of another intersection. That is to say the coupling relationship of intersections could not be reflected, so the method of two-intersection traffic control was proposed. The optimal model of adjacent intersection was built, and the objective function and its constraints were obtained. It was optimized by using improved genetic algorithm. The simulated software of two-intersection traffic control was developed, and the control effect was satisfying.
