冰雪条件下信号交叉口的交通流与正常天气下相比会在定性和定量两方面产生变化，针对这一问题的专项研究是研究冰雪条件下信号交叉口周期优化和通行能力的基础和前提。文中从信号交叉口车流特征出发，系统研究单点控制信号交叉口的车流基本参数在冰雪条件下的特性变化，并着重研究信号交叉口车辆时间损失特性，建立了冰雪条件下信号交叉口车辆延误时间影响模型。进一步以信号交叉口各进口道和整体交叉口车流为对象，根据自然形态区分的各类冰雪条件分别进行研究和建立相应模型，通过模型计算与实测结果的比较分析得出结论。

Traffic flow characteristic will change on the ice and snow condition in qualitative and quanti-tative aspects compared with normal weather .Special study on the issue is the basic and prerequisite for optimization of periodic signal intersections and traffic capacity on ice and snow conditions .In the paper ,we propose traffic flow characteristic basic parameters changes of single point control signal in-tersection in the ice and snow conditions ,and focus on the traffic time loss characteristics .Further-more ,we study the signal interaction imports and the whole traffic flow ,and establish model accord-ing to the natural form on all kinds of ice and snow conditions .We gain the conclusion through the model calculation and measured results .
