Air Pollution and Urban Morphology: A Complex Relation or How to Optimize the Pedestrian Movement in Town

Description

Urban air pollution is traditionally estimated by using techniques based on geostatistical methods, such as interpolation, applied to a set of data stemming from measures of stations of pollution. Now very often, these stations are in insufficient number or do not measure the same pollutants to allow mapping finely dispersion of air pollution through urban spaces. Numerous studies work then from land registries of broadcasts. Although interesting in a regional scale, these studies bring only not enough information in the understanding of the phenomena to a scale as fine as the intra-urban. So, it is necessary to resort to the fine three-dimensional modelling to dread this intra-urban scale and it is what we describe now.
