Abstract

Fixing the accessibility is a standard issue of transport analysis, which can be of interest to many socioeconomic applications. In this paper we propose and discuss accessibility based Lithuanian automobile transport system analysis and a GIS (geographic information systems) calculation method for searching for potential territory according to different conditions. The main parameter is time based accessibility from the centres of Lithuanian administrative regions. Also other factors have been included such as the road network density in regions, density of local roads in regions, length of roads for 1000 inhabitants in administrative regions, length of local roads for 1000 rural inhabitants in administrative regions; GIS application computes the ratings for administrative regions. The first stage of GIS decision support system is based on two calculation methods: Topsis (Technique for Order Preference by Similarity to Ideal Solution), and SAW (Simple Additive Weighting). The second stage of the GIS application is for forecasting of potential residential areas. The major input GIS data for this application is the road and street network. Minor data include layers of buildings, engineering utilities and landscape, hydrology, culture heritage objects. Also, the application user can enter different technical parameters: driving time from the centre, possible distance from major roads, distance from concrete utility, etc. All users parameters entered would be used to generating output a GIS data potential area; which satisfies all conditions entered and protective zones of different objects. Keywords: accessibility, GIS, automobiles transport system, road network.
