Urban mobility plan environmental impacts assessment: a methodology including socio-economic consequences - The Eval-PDU project

The project objective is to develop an optimized methodology to assess the environmental impacts of urban mobility plans (UMP, in French PDU), taking into account their social and economic consequences. The main proposed methodology is based on a systemic approach: multi-factor (air quality, noise, energy consumption, greenhouse gas emission) numerical simulations with a chain of physically-based models, based on alternative and comparative scenarios. The social and economic consequences of these alternative simulations are assessed by means of econometric models. Two alternative approaches are explored: (i) the use of composite environmental indicators to correlate the sources to the impacts, especially health impacts, and (ii) the analysis of sample surveys on what makes inhabitants' quality of life, well-being and territorial satisfaction and on citizens' behavioral changes linked to transport offer changes.
