This includes using different transport modes, such as walking, cycling, driving and using public transport, like busses, trains and mini-bus taxis. These transportation systems have their own issues, and limitations which form barriers for those who depend on them. Climate change is becoming a big issue in transportation systems globally, with the rise of temperatures worldwide that are triggering catastrophic weather events that end up changing the area landscape. These changes affect and ruin transportation infrastructure compromising overall mobility. This essay explores the impacts of floods on transportation systems and the challenges they pose to mobility in urban and rural areas, as well as solutions to the problems. Flooding in South Africa causes major mobility challenges by interfering with transportation systems such as roadways, airports, railways and public transit. Airports close during floods which disrupts the national and regional trade and flooded dirt roads can isolate rural communities. These issues are made worse through urban inequality, with infrastructure differences between rural and urban areas and with informal settlements being built in flood-prone areas, overwhelming the existing drainage and stormwater systems. To combat this new technology and road pavements are designed to be able to coexist with the current problems. This essay covers the impact of floods in South Africa on transportation systems affecting mobility and how flood modelling and resilience assessment will be required to adopt and incorporate the newly designed floodway channel roads into the existing roadway systems.7 pagesPDFSouthern African Transport Conference 2025FloodsTransportation systemsMobilityArticle
