Analysis of the regional accessibility of selected basic services
Currently basic services are concentrated in cities and agglomerations. But does this mean that an under-supply exists in practice?
Basic services fulfill people’s daily needs and have implications for their living conditions. Generally it is assumed that the living conditions of people residing in rural regions are deteriorating. This is due to out-migration, demographic change and the global dynamic economic growth that are influencing each other. It is suspected that the concentration of basic services in cities and agglomerations will cause an under-supply in rural areas. Against this background the project analyses the accessibility of selected basic services near the place of residence in Germany. This is amongst others done differentiated according to different region types based on a GIS accessibility analysis below the level of communities.
In order to be able to analyze the accessibility of basic services we developed a GIS-accessibility model that allows the nationwide modeling of accessibility situations. We decided to use an approach that does not focus on Euklidean distances, but on distances and travel times in traffic networks. To be able to analyze accessibilities below the administrative level of the communities we use a vector raster (grid) of 250 m x 250 m covering Germany as base for the analysis. That is from every center (centroid) of the single grid cells we calculate the street distance and travel time to the next service location under consideration reachable. As base grid the so called EWZ25 of the Federal Institute for Research on Building, Urban Affairs and Spatial Development is used as this grid contains disaggregated population data for every grid cell based on the 2011 census. The accessibility analysis itself is based on the traffic network of the OpenStreetMap. Travel times are calculated based on the speed profiles of the OpenStreetMap for Germany.
Until now data for the following basic services are available for Germany:
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.
