Overview
Brief Summary
The study team are proposing to conduct a randomized controlled trial to determine the effectiveness of focused feedback vs standard feedback and self-chosen vs assigned goals on driving behaviors targeted by behavior-based insurance apps: hard braking, fast acceleration, handheld phone use, and speeding. The interventions arms will receive feedback on their driving behaviors, tips for safe driving, and a UBI-like financial incentive. The Penn research team will use Meta advertisements to recruit for the study and determine eligibility via an online survey. Those who enroll will undergo a 6-week run-in period during which their driving trips will be monitored by a mobile app. Individuals with a sufficient number of trips during this period will be randomly assigned to one of four arms for the intervention period. Target enrollment is 1,300 participants (325 per trial arm). The power analysis assumed an attrition rate of 20% over the course of the study.

Outcomes
Primary Outcomes
Overall Driving Score
Time Frame: 12 weeks of the intervention period + separate analysis of 6 week post intervention.
This is the mean of the four behavior scores for the intervention period (and, in a follow-up analysis of effect sustainability, the post-intervention period). Scores can range from 0 -100, 100 being the safest driving score.
Secondary Outcomes
- Distraction score(12 weeks of the intervention period + separate analysis of 6 week post intervention.)
- Speeding score(12 weeks of the intervention period + separate analysis of 6 week post intervention.)
- Acceleration Score(12 weeks of the intervention period + separate analysis of 6 week post intervention.)
- Braking score(12 weeks of the intervention period + separate analysis of 6 week post intervention.)
