Accessibility impact
These assumptions can change who appears to be well served.
Ignoring terrain overstates mean accessibility by 6.6 to 8.3% across pharmacies, playgrounds, and metro stations.
For playgrounds and metro stations, the difference reaches 20% at the 90th percentile.
For low propensity walkers, accounting for slope preferences reduces estimated accessibility by more than one third.
