摘要:使用脱机信号配时方案是目前常用的交通信号控制方法,信号相位之间“绿冲突”检验是配时方案的安全保证。通过引入“间隔矩阵法”的概念,详细阐述了一个在计算机中易于实现的“绿冲突”检验算法以及使用该方法开发的交通信号脱机配时系统;介绍了“跟车法”计算机辅助调查系统,用于收集配时参数、检测和评价信号配时效果,为交通工程师设计、评价和优化信号配时提供了一个简单和实用的方法。

Abstract: Off-line signal timing plans is one of the most common traffic signal control plans currently. And the Green Conflict testing between two phases is the safe guarantee of the timing plans. This paper firstly introduces the concept of interim matrix to describe an easy executable way of Green Conflict testing and its application in signal timing software. Secondly, it also introduces a way of on-line speed survey method called Car Following Method(CFM) to collect timing parameter and evaluate the effect of timing plans. The paper offers a simple and applied method for traffic engineer to design, evaluate and optimize signal timing plans.
