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<br />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<br />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<br />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<br />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<br />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.
A new f u--y logic cont rol model for signali-ed intersection is proposed
where t he<br />efficiency and the fairness of t raffic are considered simultaneously during t he cont rol process. The<br />model is composed of two sub cont roller s. When current green time is over
green p hase<br />cont roller evaluates all lanes-t raffic urgency degrees in t he light of t he number of vehicles and<br />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<br />conformity of the t raffic urgency degrees. The green time of t he next green p hase is determined<br />by green time cont roller according to the t raffic sit uation of the lane on which t he current number<br />of vehicles is t he largest among t hose lanes t hat belong to t his p hase. Compared with vehicle<br />actuated cont rol and Pappis-model
t he simulation result s show t hat t he cont rol effect s are<br />similar under t he condition of spar se t raffic flux ; and t
