GIS model to evaluate the accessibility to major transport ways

Abstract

In order to ensure a balanced accessibility to major transport ways, supporting spatial development and economic growth, a GIS model to assess accessibility it was proposed. The model is measuring the average cost of travel (by car, usually) from a point to a predetermined number of destinations measured in units of time (minutes). Using the ARCGIS Spatial Analyst module, accessibility territorial indicators were calculated and presented as cartograms and maps that are outlining the accessibility to major transportation routes and to major cities. The proposed model to assess accessibility was tested for Tulcea county (NUTS III level) and for the South East region (NUTS II level).
