Towards a Standard Margin of Forgiveness

A Regression-Discontinuity Study of a Residential Speed Camera's Trigger Tolerance

A research poster from the School of Emergent Priorities treats a fixed roadside camera's 54.0 km/h trigger as a natural regression-discontinuity design on one 50 km/h residential street, finding that vehicles following a flashed car ran 3.1 km/h slower over the next 40 m across 386 leader-follower pairs, and reports the School's adoption of the camera's 8 per cent margin as the tolerance on a lamp above every meeting-room door.
