This report discusses the results of a randomized field experiment aimed at improving the safety of long-distance mini-busses or matatus in Kenya. The intervention combined motivational messages that encouraged passengers to speak up against bad driving with a lottery that rewards matatu drivers for keeping the stickers in place. Independent insurance claims data were collected for more than 2000 long-distance matatus before and after the intervention.
Results
-All insurance claims fell by 50-66%
-Claims involving injury or death fell by 60%
This report discusses the results of the evaluation of a second, larger scale-up of the Zusha! sticker intervention in Kenyan matatus, or minibuses. The intervention was randomized across 12,000 vehicles.
Results
In the vehicles that received stickers:
-All insurance claims fell by 25-33%
-The effect of the stickers was equivalent to avoiding 140 accidents and saving 55 lives per year
-Maximum speed was 1-2KM lower on average
