| summary |
In several developing countries it is often assumed that low-income segments of the population living at the periphery of the cities are those affected the most by poor conditions of transportation accessibility. Inorder to gain a better understanding of the way transportation accessibility is distributed across different regions of an urban area, the main aim of this work is to analyze, making use of Spatial Statistics tools ina GIS (Geographical Information System) environment, the relationship between accessibility and geographical locations in a medium-sized Brazilian city. Data of an origin-destination (O-D) survey carried out in the city of Bauru, which brings information about four different transportation modes, were used in this study. Such data, grouped following the census tracts, were carefully examined in a Geographic Information System in order to look for spatial patterns of accessibility that are not visible inthe traditional approaches. One of the interesting outcomes of the application was the identification of regions with particular dynamics, which go against the pattern found in the overall urban area. This andother results of the case study clearly indicate that Spatial Statistics analyses in a GIS environment create a powerful tool to extend conventional transportation accessibility analysis. |
