城市道路十字交叉口通行能力研究

Research on traffic capacity of urban road right angle intersection

道路交叉口是城市路网的瓶颈,十字交叉口是交叉口的典型类型,这与城市建筑布局密切相关.通过对车道通行能力、无信号控制交叉口及有信号控制交叉口通行能力的研究,提出了提升交叉口通行能力的手段和措施,以便更好地满足道路通行的要求,进而最大限度地发挥城市道路的交通效率.

The intersections was always the bottleneck of urban road network.The right angle intersection was a typical type of intersections , which was closely related to the urban construction layout.Through studies on lane capacity , no signal control intersection capacity and signal control intersection capacity , means and measures which could improve intersection capacity were put forward in order to meet the requirements of road traffic better and to maximize the traffic efficiency of urban roads.
