城市道路交叉口直行待行区设置研究

Study on Setting up Through-movement Waiting Areas at Urban Road Intersection

完善城市道路交叉口直行待行区是城市交通精细化设计的重要设计理念之一,论文总结分析学者提出直行待行区的设置方法,提出直行待行区设置条件,为科学合理的布设直行待行区做技术支撑。通过通行能力计算模型、交通仿真对比分析有无直行待行区的技术指标,科学布设直行待行区能提升通行能力,减小行车延误,充分利用交叉口的时空资源。

Improving the direct waiting area of urban road intersection is one of the important design concepts of urban traffic fine design. This paper summarizes and analyses the methods of setting up the through-movement waiting areas proposed by scholars, and puts forward the conditions of setting up the through-movement waiting areas, and provides technical support for the scientific and rational layout of the through-movement waiting area. Through the calculation model of traffic capacity and traffic simulation, the technical indicators of whether there is a through-movement waiting area or not are compared and analyzed, scientific layout of the through-movement waiting area can improve traffic capacity, reduce traffic delays, and make full use of intersection space-time resources.
