Analysis of the regional accessibility of selected basic services
Project
Project code: TI-LR-08-PID1378
Contract period: 01.01.2012

Purpose of research: Inventory & Assessment
Currently basic services are concentrated in cities and agglomerations. But does this mean that an under-supply exists in practice?
The accessibility of basic services is assessed based on a GIS accessibility analysis. That is, the area of analysis is overlaid with a vector raster. Based on the raster centroids, the street network and the geocoded basic services for every raster cell, the shortest street distance to the next basic service is determined. Implicitly the analysis builds on the assumption that from every start-address (raster centroid) the next basic service is chosen by using the shortest street distance.
As raster of reference the populated raster cells of the Austrian Institute of Technology Population Density Grids (AIT-GRID) with a cell size of 1 km, respectively the EWZ 250 of the Federal Institute for Research on Building, Urban Affairs and Spatial with a cell size of 250 m, are used. The locations of basic services have been acquired via external data providers and have been geocoded via the address. The determination of the accessibility has been computed by GIS network analysis methods.
Until now data for the following basic services are available for Germany: 1) Street Petrol Stations (AIT-GRID) 2) Public pharmacies (EWZ250) 3) Supermarkets and discounters (EWZ250) Thereby the results of the analysed services are quite similar. In tendency longer distances have to be covered in rural areas, especially in Brandenburg, Mecklenburg-Vorpommern and in north-eastern Sachsen-Anhalt. Nevertheless the majority of people are able to access the services within a maximum driving time of 15 minutes by car. By foot within walking time of 15 minutes, except some singular exceptions, the services are only accessible in cities and agglomerations.
