| 摘 要： | 基于对城市快速路出入口匝道及辅路交叉口的交通流特性分析,利用混杂自动机原理建立了交叉口混杂切换系统模型,并结合出入口匝道的交通流密度来协调交叉口的信号控制.提出了应用模糊逻辑的方法来优化交叉口的相位切换顺序,并用Paramics微观交通仿真软件进行了仿真.结果表明该算法能一定程度上提高车辆的平均速度,是解决城市交通区域拥挤的一种有效方法.

| Abstract: | In this paper,based on the analysis of the traffic characteristic of urban freeway ramps and roadside intersection,an intersection model of hybrid switching system was built by using the hybrid automata theory.The densities of the ramps were used to coordinate the intersection signal control.A fuzzy logic method of optimizing the phase switching of the intersection was proposed and simulated via the microscopic transportation simulation software Paramics.The results indicate that the fuzzy algorithm can eff... |
