Applications

Accessibility indicators computed with the methods in this wiki are used across several domains.

National accessibility models and monitors

• Dutch national network model (PBL) — nationwide travel times for car, bicycle, pedestrian and public transport, with published methodology at geodms.nl/networkmodel_pbl. Underpins the PBL reports Toegang voor iedereen? (2022) and Beter bereikbaar? (2024).
• Planmonitor NOVI — accessibility indicators for national spatial planning policy.
• European and global network models — accessibility indicators built from OSM for the whole planet, including settlement hierarchies based on travel-time thresholds and functional rural area definitions.

Land use modelling

Accessibility measures are calculated and used as driving factors in Land Use Modelling, where the attractiveness of a location for a given activity depends on what it can reach.

Social domain

In our projects in the social domain — for instance WoonZorgWijzer — distances over the road network are calculated from dwellings to facilities such as supermarkets, care centres and public transport stops. These distances are suitability factors for housing for people with mobility impairments, where the difference between a straight line and the actual walking route is decisive; see Euclidean versus network distance.

Datasets

• PC4 travel time matrix for Nederland van Boven (in Dutch) — travel time from each PC4 postcode zone to every other zone in the Netherlands, used among other things for this analysis on nu.nl and for the VPRO programme Nederland van Boven.
• Road distances from every BAG building to the nearest primary school, made available to EduGIS.
