Crime Prevention Through Environmental Design
The same fix can work in one place
and fail in another.
Read the site and its local context, place interventions on the plan, justify each one, then review your decisions through the Physical and People lenses.
Effects shown are illustrative. This simulator does not predict or forecast crime.
How it works
- 01 Read the brief, evidence and context note.
- 02 Place 1st Gen physical and 2nd Gen social measures on the real site photo.
- 03 Justify each decision in your own words.
- 04 Submit to get a principle audit, a score out of 100 and areas to improve.
