  1. 1. Managing knowledge sharing of extreme weather induced impacts on land transport infrastructure Case study of the Swedish Transport Administration

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Monika Rydstedt Nyman; Karlstads universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lessons learned; risk management; climate change adaptation; accident investigation method; extreme weather events; natural hazard; land transport infrastructure; maintenance; lärande; kunskapsåterföring; risk hantering; klimatanpassning; olycksutredningsmetod; naturolyckor; landtransport infrastruktur; underhåll; Risk and Environmental Studies; Risk- och Miljöstudier;

    Sammanfattning : Extreme weather events and effects of climate change are threats to the transport sector’s functionality and safety. Risk management in this context implies a necessity to focus on the connection between near-term experiences and coping strategies on one hand, and long-term adaptation analyses on the other.
