提高武汉市环线平交路口通行能力交通设计技术研究

Study on Technologies of Improving Traffic Capacity of Intersection in Wuhan

为了更好地把握武汉市环线平面交叉口的现状和存在的问题,提出改善措施,采用先进的交通调查仪采集武汉市环线主要平面交叉口的交通流数据,分析其交叉口交通量空间分布、交通流稳定性、交叉口流量流向、车头时距等交通流特性,得出环线主要平面交叉口现状道路交通状况,并以此提出了通行能力改善技术,并进行了案例应用。

In order to better grasp the present situation and the existence question of intersection in Wuhan and propose the improvement measure,the traffic flow datum were collected by using advanced traffic survey instrument.According to collecting datum,this paper analyzes the traffic volume distribution,traffic flow stability,the junction flow and headway to draw traffic condition of intersection.And the techniques of improving traffic capacity of intersection are put forward.
