摘要

为了在控制过程中既强调交通效率又兼顾交通公平

提出了一种新的信号交叉口模糊逻辑控 制模型

该模型由2 个子控制器构成. 当前绿灯结束时

通行相位控制器根据各车道的车辆数和平均 等待时间计算它们的交通紧急度

然后根据交通紧急度选择下一个通行相位

通行时间控制器则根据 被选相位中车辆数最大车道的交通情况来决定通行时间. 仿真实验结果表明

该模型与感应控制和 Pappis 模型相比

在车流量很小时控制效果相近

但随着各向车流量的增加

该模型开始优于其他模 型

车流量越大优势越明显

而且变化十分平稳

不仅提高了交通效率

而且使交通供给更加公平.

Abstract

A new f u--y logic cont rol model for signali-ed intersection is proposed

where t he efficiency and the fairness of t raffic are considered simultaneously during t he cont rol process. The model is composed of two sub cont roller s. When current green time is over

green p hase cont roller evaluates all lanes-t raffic urgency degrees in t he light of t he number of vehicles and t he average waiting time

and t hen t he next green p hase get s to be selected by t his cont roller in conformity of the t raffic urgency degrees. The green time of t he next green p hase is determined by green time cont roller according to the t raffic sit uation of the lane on which t he current number of vehicles is t he largest among t hose lanes t hat belong to t his p hase. Compared with vehicle actuated cont rol and Pappis-model

t he simulation result s show t hat t he cont rol effect s are similar under t he condition of spar se t raffic flux ; and t
