ABSTRACT
Based on previous works on the connectivity index applied to the settlements of Banat (Rusu, 2007; Rusu, 2008), the paper assesses the road connectivity index for the same settlements using a slightly different approach, based on the road distance from every settlement to the nearest central places, ranked on nine levels. Therefore, it is not the position on a certain road that counts, but the means by which specific groups of people (either urban or rural communities) might access a set of services or facilities deemed socially necessary and located in the above-mentioned central places. The welfare of the communities depends mainly on the standards of connectivity and accessibility to such services or facilities. We considered that the most valid measure of connectivity would then be the assessment of the space (distance) needed to be crossed for the population of every settlement to reach specific destinations. The overall values for each settlement have been interpolated using GIS in order to produce a map of the road connectivity index in Banat. The map clearly shows the existing disparities between well-connected regions, especially around the main cities, and isolated areas, usually in the mountains, the hills or along the borders.
