Abstract [en]

Road infrastructure has effects on the environment throughout all of its life cycle phases: construction,maintenance, operation and end-of-life. It has been observed, however, that these life cycle impacts are notusually considered during early stages of road infrastructure planning (i.e. decisions on road corridor).The recently developed LICCER tool enables assessment of road corridor alternatives during early stages of roadinfrastructure planning. It includes input data for roads, bridges and tunnels. It also considers future emissionsfrom traffic. The life cycle impact categories covered are energy use and contribution to climate change.The developed tool is being tested in a case study. Construction of a specific road in Sweden was used todemonstrate how the model is able to show differences between road corridor alternatives. Sensitivity analysiswas applied to show the robustness of its results.

Abstract [fr]

L'infrastructure routière a des impacts environnementaux dans toutes les différentes étapes d'analyse du cycle devie : la construction, l'entretien, l'utilisation et la fin de vie. Il a été constaté, cependant, que ces impacts du cyclede vie ne sont généralement pas considérés dans les premiers stades de la planification de l'infrastructure routière(en décident sur le corridor de la route).L’outil LICCER récemment développé permet d'évaluer des alternatives de corridors routiers au cours despremières étapes de la planification de l'infrastructure routière. Il comprend des données d'entrée pour les routes,les ponts et les tunnels. Il considère également les émissions futures de trafic. Les impacts environnementauxconsidérés sont la consommation d'énergie et contribution au changement climatique. L'outil est testé dans uneétude de cas. Construction d'une route spécifique en Suède a été utilisée pour démontrer comment le modèle estcapable de montrer les différences entre les alternatives de corridors routiers. Une analyse de sensibilité a étéeffectué de montrer la robustesse de résultats.
