Modélisation de l’impact du trafic routier sur la pollution de l’air et des eaux de ruissellement

Abstract : Road traffic emissions are a major source of pollution in cities. Modeling of air and stormwater pollution due to on-road vehicles is essential to understand the processes that lead to the pollution and to provide the necessary information for the development of effective public policies to reduce pollution. The objective of this thesis is to evaluate the feasibility and relevance of modeling chains to simulate the impact of road traffic on air and stormwater pollution. The first part of the thesis consisted in assessing the state of the art of modeling tools available for the different relevant phenomena (traffic, emissions, atmospheric dispersion, and stormwater quality), highlighting challenges associated with the integration of the different models to create a consistent modeling chain in terms of pollutants and spatio-temporal scales. Two examples of modeling chains have been proposed, one static with hourly time-steps, the other based on a dynamic approach for traffic and its associated pollution. In the second part of the thesis, different interface tools have been developed to link models and construct modeling chains. These modeling chains were tested with different case studies: (1) coupling traffic and emissions for the simulation of an urban street using a dynamic model of traffic with instantaneous and time-averaged emission models, (2) coupling on-road emissions and atmospheric dispersion/deposition near a freeway, (3) coupling traffic, emissions and atmospheric dispersion/chemistry near a freeway, (4) coupling emissions and atmospheric dispersion/deposition in a suburban neighborhood (5) coupling atmospheric deposition and stormwater quality for an urban catchment, and finally (6) a complete modeling chain with traffic / emissions / air and stormwater quality models for urban catchment drainage. This work allows one to identify different possibilities of model integration to calculate air and stormwater pollution due to road traffic in urban areas. Moreover, it provides a solid basis for the future development of integrated numerical models of urban pollution
