Intense rainfall induced by climate warming is causing more common extreme meteorological events such as urban waterlogging in recent years. The urban waterlogging often has a wide-ranged severe impact on urban traffic. General intense rainfall weather makes urban transportation frequently be served in an environment with abundant water, which not only affects its operation safety but also challenges the service life of urban asphalt pavement. This paper presents a comprehensive survey on the influence of intense rainfall on urban transportation. The characteristics of meteorological phenomena such as climate warming, intense typhoon and rainfall, and urban waterlogging are firstly discussed. Then, Shenzhen, the city in south China, is chosen to analyze its historical meteorological variation in recent years, which was recently affected by a typhoon name Ewiniar in 2018 and caused severe waterlogging throughout entire city. Further, the operation safety of urban traffic is investigated with an increasing depth of surface runoff in intense rainfall weather, followed by the service life of asphalt pavement related to the moisture damage induced by dynamic pore water pressure. Finally, a series of measures to alleviate the effects of intense rainfall induced by climate warming on urban waterlogging and long service life of asphalt pavement are recommended.
