WEATHER : Weather Extremes: Impacts on Transport Systems and Hazards for European Regions


The WEATHER project approaches the topic of present and future impacts of extreme weather events on the transport system from an economic perspective. It quantifies in monetary terms the costs and benefits of different abatement measures and of alterative emergency strategies.

The project core objective is to "determine the physical impacts and the economic costs of climate change on transport systems and identify the costs and benefits of suitable adaptation and emergency management strategies".

The project provides some insight on the expected changes in climate in Europe in the next 40 years, and the increase of extreme weather events. The predicted change in average costs due to weather extremes in the next 40 years point to regions, where transport systems are affected above average by extreme weather events, in particular France, Middle Europe and the Alpine region as well as at the probably most affected modes of transport, in particular rail transport. These regional and modal core areas must be focused on future climate change adaptation policies.

The need for expensive investments in transport infrastructures can be limited or at least postponed by good maintenance practices, which are sensitive to the impacts of changing climate and weather conditions. With adapted maintenance routines, most infrastructure measures should be possible within standard renewal cycles of the assets, and thus will cause zero or only moderate additional costs.
