This research develops a transportation decision support model, in GIS environment using a combination of mathematical and spatial information to help in the process of residential site selection in urban transportation network. The most important conclusion is selection of interactively their site within accessible and non-polluted area. Urban transportation planning includes several economical, technical and environmental criteria. Several tasks are involved in the transportation planning phase, and important one of them is the understanding of the present statue and possible improvement and development of landuses. Information on landuse is required at different stages of planning to set the direction, goals and policy formulation of landuse plans. Spatial tools such as GIS, RS and GPS can be useful to arrange this information. Along urbanization growth, there is an increasing commercial, residential and transportation infrastructure development. This development normally involves to negative impact on the environment, one of these impacts is due to location of residential landuses in unsuitable areas, and this impact should be removed by consideration of two important infrastructure elements of urban transportation: accessibility and air quality. The use of GIS in selection process for locating a residential landuses in a suitable area will reduce the time and enhance the accuracy. This paper highlights a method.
