摘要:为缓解城市道路信号交叉口的交通拥堵问题,分析研究城市道路信号交叉口综合待行区的设置方法与交通控制方式。对综合待行区的基本概念、设置与控制方法、通行能力计算与运行效率评价等方面进行较为全面地阐述,并且以综合待行区的一般形式作为研究对象进行软件仿真实验,为进一步研究与其推广应用提供理论基础。结果显示,对于本文所研究的综合待行区一般形式,综合待行区的设置可以使综合车均延误缩短约一半,行车效率得到大幅度的提升。因此,在条件具备的交叉口进口道处合理地设置综合待行区的控制策略,能够充分利用道路时空资源、减小车辆通过交叉口的延误、提升交叉口通行能力,对于缓解城市交通拥堵具有十分重要的推广意义。

Abstract:To alleviate the traffic congestion problem at signalized intersections,the setup method and traffic control theory of integrated waiting area are analyzed.The basic concept,setting and controlling method,capacity calculation and operation efficiency evaluation of integrated waiting area are expounded,then general format of integrated waiting area is simulated,which provides the theoretical foundation for further research and its application.Software simulation results which are based on the general format of integrated waiting area demonstrate that the setting of integrated waiting area can halve the comprehensive average delay and greatly improve the traffic efficiency.Consequently,the setting of integrated waiting area at appropriate intersections can make full use of road spacetime resources,improve the traffic capacity of intersection and reduce the traffic delay,which is of great significance to alleviating urban traffic congestion.
