摘要
基于信号交叉口的灰色系统特性,通过引入未确知模型,以排队长度、延误、负荷系数、受阻车辆率、效率系数作为评价指标,建立信号交叉口运行状况评价的新方法。最后以南京某信号交叉口作为实例进行分析,结果表明,未确知模型的信号交叉口评价方法效果显著,具有较强的实践性。
Based on gray system features of the intersection,this paper introduces an uncertain model which uses queue length,delay time,the loading factor rates of the blocked cars and the efficiency factor as evaluation indicators.A new method to evaluate intersections is established.Finally,an intersection of Nanjing is used as an example to make an analysis,and the result shows that evaluation system of junction of the unknown model has distinctive effect and the new method has a better practical usage.
