| 摘 要： | 为了解公路环形交叉口的运行状况,需对其进行延误研究。运用间隙接受理论,通过概率分析方法,考虑公路环形交叉口多种混合车型条件下的延误,在此基础之上建立公路环形交叉口的延误模型。应用该模型,得出延误理论值,与实际调查所得延误值进行对比分析,证明该模型的可行性。

| Abstract: | In order to solve the bottleneck problem of roundabout,it is necessary to study the delay of the existing highway roundabouts.This paper,based on gap acceptance theory,analyzes the delay of the highway roundabout with multi-vehicle-type mixed traffic flow with probability theory,sets up the delay model of the highway roundabout with multi-vehicle-type mixed traffic flow.Using the delay model,it can get the theoretical delays.Then,the actual delays of the survey are compared to prove the feasibility of the delay model. |
