Indicator generated by accessibility model based upon a GIS road, rail and air network datasets, a GIS NUTS-3 region layer and NUTS-3 region population figures. First, accessibility for the individual modes is calculated; then, the multimodal accessibility potential is generated as logsum over all individual modes.
The indicator is available in ESPON for three distinct years, 2001, 2006 and 2011 for entire ESPON space. Neighbouring countries are, however, not yet included.
Since changes in road and rail networks take place slowly, a 5-year update interval for this indicator is justified.
Data available at NUTS-3 level and higher.
