摘要：绿灯间隔时间是保障信号控制交叉口交通流运行中，上 一相位清空交通流与下一相位进入交叉口的交通流不发生冲突 的安全间隔时间，包括黄灯时间和全红时间(部分国家和地区采 用红灯+黄灯时间)，是影响信号控制交叉口安全和效率的关键 参数。然而，目前国内还没有绿灯间隔时间计算方法的国家标 准。首先介绍了绿灯间隔时间的基本概念及国内研究概况，然 后分析比较了各国绿灯间隔时间的计算方法，并探讨了其影响 因素(包括清空距离、进入距离、清空速度、进入速度、坡度、车辆 长度、通过时间)。最后提出了我国绿灯间隔时间的计算准则、 具体计算思路、分层分析方法及相关参数取值应考虑的问题。

Abstract：The objective of green interval is to separate conflicting traffic flows at signalized intersection. The duration of green interval, along with amber and red intervals, is a key design variable in providing efficient and safe operation at intersections. However, there is no formal specification on how to design signal timing in China. This paper first reviews the basic definition and research on green interval in China. Through comparing various signal timing design methods from other countries, the paper discusses the influencing factors in designing green intervals such as clearance/entering distance, speeds, approach slopes, the length of vehicles, and crossing time. Finally, the paper proposes the calculation principles, detailed calculation steps, analysis method, and value of relevant key parameters.
