摘要

针对排队车辆在一个绿灯相位内不能完全消散的情况，建立了过饱和状态下道路单交叉口的延误模型。随着物联网技术及数据采集与处理精度的提高，可主要分析测量断面车辆到达率和离开率的相关规律，经机理分析，分别对单相位路口、两相位单交叉口和四相位单交叉口进行建模。采用所建立的过饱和交叉口延误模型，可寻求最小延误重新分配各路口的绿灯时间，以缓解城市道路过饱和的状况。仿真结果验证了所建模型的准确性。

Abstract

The oversaturated state of the intersection is mainly manifested as the queuing vehicles are not completely dissipated at the end of a green light phase.In order to cope with the traffic congestion

the mathematical model of an intersection is built.The relative regularity of arrival rate and departure rate of vehicles are analyzed.Through the analysis of the mechanism

the modeling of single-phase intersection

two-phase single intersection and four-phase single intersection are studied.The established oversaturated intersection delay model can be used to assign the green time of each intersection by calculating the minimum delay to alleviate the oversaturation condition of the city road.Numerical simulation results verify the validity and availability of the modeling method.
