increasing urban network has both positive (accessibility) and negative (air pollution) impacts. in this research air quality is chosen as key elements with respect to their critical roles in quality of life and urban health. the overall objective of this study is to develop a mathematical model to plan appropriate locations for residential land uses and urban transportation network development...

Despite their importance for pollutant dispersion in urban areas, the special features of dispersion at street intersections are rarely taken into account by operational air quality models. Several previous studies have demonstrated the complex flow patterns that occur at street intersections, even with simple geometry. This study presents results from wind tunnel experiments on a reduced scale...

The monitoring and modelling of the evolution of urban areas is increasingly attracting the attention of land managers and administration. New data, tools and methods are being developed and made available for a better understanding of these dynamic areas. We study and analyse the concept of landscape fragmentation by means of GIS and remote sensing techniques, particularly focused on urban are...
