| 摘 要： | 入口匝道控制是缓解快速路交通拥挤最为有效的措施之一。首先分析了快速路交通流的运行特性和匝道控制模型。提出了考虑相匝道交通运行状态的入口匝道模糊控制方法,该方法以两个相匝道的上游交通密度和入口匝道排队长度为模糊控制的输入量,建立了包含13条模糊控制规则的规则库,利用MATLAB工具对该控制系统进行了仿真实验,实验结果表明该模糊控制器在快速路入口匝道控制中具有良好的应用效果。

| Abstract: | On-ramp control is one of the most effective measures to combat traffic congestion of urban expressway.The characteristics of traffic flow and the model of on-ramp control are analyzed,and a fuzzy control measure is put forward,which takes traffic conditions of neighborhood on-ramp into account.Three fuzzy variables including density of one expressway section,the density and queue of the(upstream) section are taken as inputs,and 13 rules is established.The control system is simulated with MATLAB software,and the result indicates that the fuzzy controller is effective to the on-ramp control. |
