Research on impact of flooding on urban transportation safety

Abstract

Extreme rainfall is one of the more serious disasters in recent years, and in recent years, many parts of the country have suffered from urban flooding generated under extreme rainfall, and the impact on transportation has been enormous. Researchers at home and abroad have found measures to cope with urban flooding in terms of transportation, but most of them are localized to explore the underground transportation or above ground transportation problems, and lack of a unified explanation. Therefore, the research theme of this paper is the measures of urban transportation to cope with urban flooding. The research method is as follows: this paper takes Zhengzhou City and several cities in Canada as examples and summarizes the impact of urban underground and above-ground transportation on extreme rainfall and the measures to cope with it in various places through the form of literature review. The study found that the improvement of drainage pipes for better drainage, as well as real-time monitoring of rainfall in the event of flooding, and the timely deployment of escape measures.
