Data Collection, Baseline and Endline Surveys, and Randomized Control Trials in Africa
Georgetown University’s Initiative on Innovation, Development and Evaluation (Gui2de) was researching different interventions to improve road safety and decrease road deaths and accidents in East Africa. Beginning in Kenya, stickers were placed inside buses with motivational messages encouraging passengers to speak up directly to their driver against bad driving. Results from multiple studies proved that buses in which these stickers were placed had between 25-50% fewer insurance accident claims, translating into 140 avoided accidents and 55 lives annually. Gui2de wanted to scale this intervention to Tanzania.
Over the course of 1 year, DDD’s field research team randomly selected, inspected, and placed stickers inside over 1,200 public buses encouraging passengers to speak up against reckless driving. DDD then collected accident data from police stations in 26 regions in Tanzania, digitizing and cleaning up the data in order to analyze and compare accident rates among vehicles with/without stickers.
Through this project, Gui2de was able to collect and analyze important data to increase the effectiveness of road safety interventions in Tanzania.
