    Sammanfattning : Since ancient times, roads have tied people and cultures together. Roads have been createdwith the aim of facilitating trade and cultural exchange among different regions in the world. LÄS MER

  3. 2. Winter Road Conditions and Traffic Accidents in Sweden and UK - Present and Future Climate Scenarios

    Författare :Anna K Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Winter road condition; Slipperiness; Traffic accident; Winter road maintenance; Climate change;

    Sammanfattning : This thesis investigates the distribution of slippery roads in Sweden and the UK for the present climate and how this may be affected by climate change for the rest of the century. It also addresses future scenarios for traffic accidents and winter road maintenance. LÄS MER

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

    Författare :Monika Rydstedt Nyman; Lars Nyberg; Magnus Johansson; Eva Liljegren; Peter Söderholm; Karlstads universitet; []
    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.
