In this study, we use a randomized controlled trial in Germany and GPS-based mobility data from over 400 participants to evaluate the impact of a one-month free public transport ticket on individual travel behavior. Our findings show that the subsidy causes a statistically significant increase of approximately two trips per month—primarily through local rail services—during the subsidization period. This increase does not substitute for car trips, nor does it lead to persistent behavioral changes after the subsidy expires. These results suggest that short-term free passes may have limited effectiveness in promoting lasting shifts toward sustainable mobility.
