信号交叉口影响区确定方法研究

根据车流在不同城市道路单元上的不同运行状态，将路段进一步划分为交叉口影响区和基本路段．提出以相邻交叉口信号相位差循环周期内的周期平均最大排队长度为依据来划分，并建立了相应的排队模型、讨论了相邻交叉口信号相位差循环特性以及交叉口影响区的确定方法，给出了算例分析。其研究思路和结论可服务于路网容量研究和通行能力研究。

Study on the Determination of Signal-controlled Intersection Effect Section

According to the different moving conditions of urban traffic flow, road is divided into two parts：basic section and intersection effect section.Based on periodic maximum queue length during a period of phase dispersion between two intersections and queue length model, phase dispersion characteristic between cycle intersections, determination of intersection effect length as well as an numerical example are given in the paper. The method and conclusion could be applied to the research of road network capacity.
