摘　　要：在城市洪涝灾害频发和内涝下交通问题突出的背景下,针对城市内涝对道路交通的影响评估问题,梳理了国内外研究成果,对城市内涝模拟原理以及常用的城市雨洪模型的特点进行了分析,总结归纳了城市内涝对道路交通的影响评估方法,论述了微观交通仿真模型的构建和应用,提出了城市内涝对道路交通影响评估可优化的方向。指出在现有软件缺失和条件有限的情况下,基于积水深度与行车速度的关系式将城市雨洪模型和微观交通仿真模型进行集成,用于分析内涝下交通问题是较为有效的手段;城市内涝对道路交通的影响十分显著,通常反映在道路(损失、性能和结构)、交通工具(行驶速度和安全性)和驾驶员(心理和生理变化)3方面,以及道路交通工具驾驶员的综合影响。Against the backdrop of frequent urban flood disasters and prominent traffic problems caused by waterlogging,this paper summarizes the research results at home and abroad on the impact assessment of urban waterlogging on road traffic.This paper analyzes the principles of urban waterlogging simulation and the characteristics of commonly used urban rainwater flood models,summarizes the methods for evaluating the impact of urban waterlogging on road traffic,discusses the construction and application of micro traffic simulation models,and proposes the direction for optimizing the impact assessment of urban waterlogging on road traffic.It is pointed out that in the absence of existing software and limited conditions,integrating urban rainwater flood models and microscopic traffic simulation models based on the relationship between waterlogging depth and driving speed is an effective method for analyzing traffic problems under waterlogging.The impact of urban waterlogging on road traffic is very significant,usually reflected in three aspects:road(loss,performance,and structure),transportation vehicles(driving speed and safety),and drivers(psychological and physiological changes),as well as the comprehensive impact of road transportation vehicles drivers.
