What Affects This Score
The city model estimates walking conditions from mapped road attributes:
- Increases stress: High speed limits, multi-lane roads, highways, missing sidewalk tags on some road types
- Decreases stress: Bike lanes, traffic calming, street lighting tags
The snapshot includes 55,404 mapped road/path records. The city builder weights road types differently; this is not a safety assessment.
