Impact of Public Bicycle Share Programs on Bicycling Collisions

This project evaluated how implementing public bicycle share programs (PBSPs) affected the likelihood of bicycling collisions across multiple North American cities. Using a difference-in-differences approach applied to repeated cross-sectional survey data, it shows that crash odds did not increase after PBSP implementation and were notably lower in cities with existing programs, supporting the safety of well-established bike share systems.

Impact: Offers empirical insights to urban planners and policymakers assessing the safety implications of bike share adoption.

Tech Stack: R, quasi-experimental design (difference-in-differences), multi-city survey analysis
