7. Good data go in – accurate locations come out
Latitude – Longitude:  | 

8. Methodology GIS data used Approach Coordinates of primary schools
Population density grid
Communes
NUTS 3 regions
Road network
Approach
First direct distances to schools
Next the weighted distance based on the population
Finally the weighted average distance by NUTS 3 and also communes

10. School locations

11. Population density grid

13. Worst Case Scenario Situation inside a NUTS3 area not uniform
Selection of the commune having the maximum average distance per NUTS 3 region

16. Travel times
Simplistic model based on road network

17. Result

18. Future Work Improve the road network and the model
Investigate artefacts (“Tyrol effect”)
Verify the correlation between population density, school location density, and transport network density
Extend the exercise to other types of services
