1、 1 摘要摘要 随着经济的快速发展和城市化进程的不断加快，城市交通量急剧增加，引发 了一系列严重的交通问题和社会问题。作为交通网络重要组成部分的交叉口，往 往是交通拥堵、交通事故、交通延误等交通问题的多发地带，成为整个交通网络 的瓶颈。近年来，淄博市张店区交通问题日益凸显，整个城市的交通设施、管控 水平急需进一步组织优化。因此，本文结合张店交通实际，深入研究平面信号交 叉口的交通组织优化方法，具有重要的现实意义和实用价值。 本文首先运用交通流理论分析了交叉口处的交通流运行特性， 揭示了交叉口 交通问题的成因和根源， 为解决此类问题找到了切入点和依据。 接着从优化原则、 放行方法、渠化设计和信号

2、优化控制等几个方面，详细探讨了平面信号交叉口交 通组织优化理论和方法， 指出了各种优化措施的实施方法、 适用条件和注意事项。 最后，利用本文所研究的优化理论对张店南京路与新村路交叉口进行优化设计， 并运用 VISSIM 仿真软件进行仿真实验。仿真结果表明，根据本文研究的交叉口 交通组织优化理论为解决交叉口交通问题提供了方法和依据， 提出的优化方案具 有很强有效性和可行性。 关键词关键词：平面信号交叉口，交通组织优化，放行方法，渠化，信号控制 2 Abstract With rapid development of economy and the accelerating process of

3、urbanization, the urban traffic flow has been increased sharply, which brings a series of traffic problems and social problems. As an important component of traffic network, the intersection with signals is always regarded as the frequent issues area of traffic jams, traffic accidents and traffic de

4、lays etc.,meanwhile, it will be the bottleneck for the entire transport network. Recently, the traffic problems in ZiboCity zhangdian district have been emerged up, simultaneously, the transportation facilities and managements in this city need further optimization urgently. Therefore, there is a de

5、ep research on optimization methods of traffic organization for intersections with signals in Zibo City zhangdian district in this paper. It will have important significance and practical value in future. Firstly, the characteristics of traffic flow in intersection is analyzed in traffic flow theory

6、 in this paper, and the causes of traffic problems occurred in intersection are also revealed to solve such problems. Secondly, the theory and methods of traffic organization optimization for intersection with signals are discussed in detail through optimization principles, discharging method, channelization design, signal optimization control and so on. The suitable conditions, implementing methods, and cautions for optimization methods of traffic organization have been put forward. Finally, Z
