A month after initiating a fully free pass program for city buses, São Caetano do Sul in São Paulo, Brazil, saw its public transit user numbers more than double from 25,000 to 52,000 daily. Notable impacts include a decrease in health system appointment reschedules, fewer cars in terminal queues, and significant savings for residents who previously paid bus fares. The mayor highlights the social right to free public transportation and expects more economic returns from the program by 2024. The city is the 26th and most populous in São Paulo to adopt this initiative.
