Stronger tropical cyclones inundate and damage transportation infrastructure, resulting in delayed delivery of goods and services.Īdverse impacts to transit time, delivery reliability and efficiency in turn affect the cost of all goods transported by these systems. Higher temperatures buckle railroad tracks and roadways. Rising sea level and more intense flooding affect the safety and functionality of bridges and trestles. Railways, ports, piers, highway culverts, bridges and other transportation infrastructure have been optimized for the expected range of weather conditions that we call “climate.” When the weather becomes more extreme-more outside the bounds of what is considered “normal” climate-the transportation infrastructure becomes less reliable and less safe. Daily operational decisions in the transport sector, such as the amount of cargo that a plane or a barge can safely handle, must take weather conditions into consideration.Ĭlimate, on the other hand, affects transportation infrastructure. Weather affects the operation of the transportation systems that we all rely on-from automobiles slowed by a wet surface, to delivery trucks delayed by high winds, to passenger trains stalled by ice and snow.
