NetworkModel_EU is a spatial modelling framework for analysing school (and other service) accessibility across European countries. It combines network-based travel time computation with facility location optimisation to support policy questions around service coverage, scale efficiency, and school network restructuring.

The model is developed by Object Vision b.v. as part of the CRISP-EU project for JRC.

How it works

1. OD matrix — GeoDMS computes travel times between population grid cells and candidate facility locations using a road network, and exports the results as Arrow files.
2. Facility location — A Julia script reads those files and selects which facilities to keep open, trading off aggregate travel cost against scale inefficiency (under-enrolled facilities).
3. Accessibility output — GeoDMS reads the open/closed decisions back and produces accessibility indicators on a 1 km grid.
