Lack of urban accessibility and mobility are transportation systems problems caused, mainly, by the saturation of the road system capacity. This is materialized in terms of congestions, pollution and traffic accidents, threatening the life quality and competitiveness of urban areas, as well as have negatively affected sustainable development. The costs arising from such imperfection of the transportation system (externalities) affect, among other economic sectors, the real estate market. One of the reasons is the absence of planning support tools. In order to fill this gap, this paper aims to investigate geoprocessing tools to land use – land price analysis, through transportation database. The article discusses how the concentration of origins and destinations of urban trips shape land use and influence land price. The study area São Paulo City, a megacity with more than 11 million inhabitants, and the database consists of a thematic map of land use generated through remote sensing satellite imagery classification, data from an Origin / Destination Home-interview Survey held in 2007 by the São Paulo Metropolitan Company (METRÔ - public company responsible for operating the subway trains), São Paulo city highway network, and georeferenced data about the official value of land and edification provided by the Municipality of São Paulo (2010). It is performed a spatial analysis by using origins – destinations data, and is identified the areas with the high number of urban trips, the accessibility and mobility are assessed, and is compared with the land price that the municipality uses in order to calculate fees and taxes. Besides, the socioeconomic aspects of the traffic zones such as number of jobs, number of households, information about the population (average family income, education, gender, age, etc.), amount of school enrollment, and so on, are taken into account in order to characterize the sites regarding to real estate market.
