Eval-PDU: urban traffic and its environmental impacts modelling to assess Urban Mobility Master Plan : Conception of a methodology based on the Nantes case
Résumé
The Eval-PDU research, funded by French National Research Agency' program Sustainable City, aims at testing methodologies for Strategic Environmental Assessment of Urban Mobility Master Plans with an application to Nantes Metropolis. The general approach used for this interdisciplinary research consists in combining several modelling of flows: first vehicles flows in the city, then the flows of atmospheric pollutants and noise pollution resulting from the traffic. In front of phenomena that are quite impossible to be precisely measured considering their micro-local diversity, modelling seems the only solution to estimate the effect of transport policies on the urban environment (in comparison with a reference situation where they are not applied) and thus to enlighten collective action in order to minimize negative externalities.
