为科学分析降雨对城市交通系统的具体影响，提出了合理的预警对策方案，定量分析了可见度与路面积水对速度、通行能力及出行延误的影响机理，并对降雨后各种交通方式效用值的改变进行了定性分析。在此基础上，针对降雨时交通管理的实际需求，提出了降雨时城市交通系统应急预案的处理流程，并给出了具体的城市交通预警对策。

To analyze the specific impact scientifically on the urban transportation system and propose a reasonable early warning response option, the paper illustrates the mechanism quantitatively that the change of visibility and surface water cause the change of speed, traffic capacity and travel delay. It also includes the qualitative analysis on the change of utility values of various modes of transportation during the rain and after rainfall. On this basis, contingency processing plan is proposed for actual need of traffic management as well as a specific early warning strategy of urban transport system.
