See the Sign, Avoid the Fine : TSZ Parking Signs in Vancouver Chagani, Parinda; Lai, Eva; Jensen, Carl; Hardisty, David J.
This project aimed to improve compliance with temporary parking restrictions in the City of Vancouver. New “Behavioural Insights informed” parking signs incorporated salience and loss aversion. Control and BI-informed signs were compared in a randomized controlled trial. The BI-informed signs reduced parking violations by 57%. Although this difference was not statistically significant, it may be managerially significant. The project team recommends extending the trial to collect more data, trialing BI-informed signs for other types of parking zones, and conducting a cost-benefit analysis to inform scaling decisions.
