摘要： 在信号交叉口，全红时间可以减少冲突流中上一相位黄灯尾车与下一相位绿灯启亮时头车发生碰撞的概率，提高车辆通行安全性.本文介绍了国内外信号控制交叉口全红时间的研究概况，分析比较现行全红时间计算方法.针对当前信号交叉口由于全红时间设置不当，可能导致通行效率不高、安全性差等问题，分析上一相位黄灯尾车和下一冲突相位绿灯头车在相位转换期间，行驶至冲突点的实际驾驶行为和运行轨迹，结合交叉口限速、几何条件，以及倒计时设施等客观因素建立分析模型，提出全红时间计算方法，旨在提高车辆在交叉口通行效率和安全性.

Abstract: In signalized intersections, red clearance can reduce the conflict probability during the change interval and improve the traffic safety.This paper introduces the current situation on the red clearance both in China and other countries.It then reviews various red clearance calculation methods in the world.In view of the current traffic inefficiency and poor safety owing to the improper settings of red clearance, the paper proposes the calculation formula by analyzing the vehicle’s practical driving and tracks during the change interval.Considering the influential factors including proposed speed limit, geometric conditions, countdown display units of the intersection, etc, the paper thus improves the traffic efficiency and safety of the intersections.

Key words: urban traffic, signalized intersection, conflict point, red clearance, change interval
