The Impact of Free Bicycle Sharing Program on Travel Behavior, Road Safety, and Air Quality National Taiwan University, Taiwan Cities around the world have adopted shared micro-mobility programs to enhance public transportation networks and accessibility, and many continue to explore trategies to improve the programs’ socio-economic impacts. We provide evidence on the effects of offering free access to bicycle sharing on travel behavior and road safety, leveraging a natural experiment in Taipei—home to the world’s largest station-based bicycle sharing program—where a per-ride subsidy of $0.17 USD makes rides under 30 minutes free of charge. Using difference-in-differences designs and multiple administrative datasets, we find that the policy increases shared bicycle ridership by more than 30% and reduces motor vehicle traffic volumes by 5%. Consistent with these changes, traffic accidents involving casualties declined by more than 5% following the policy implementation. We do not find statistically significant changes in air quality. Combining these estimates with the social costs of traffic accidents yields a benefit cost ratio exceeding 10. The outsized increase in shared bicycle ridership suggests that individuals respond disproportionately to zero prices or exhibit a low value of travel time when it comes to short trips. | |
