The COVID-19 pandemic had significant effects on urban mobility and urban public transport (UPT), and as health restrictions were eased, there was a partial resurgence in people's movement in urban areas. Nevertheless, the volume of transported passengers remained lower than pre-pandemic levels, with a global average in 2022 being 26% less than that in 2017. UPT is of utmost importance in ensuring urban mobility and sustainability and represents a fundamental right for citizens, yet its sustainability relies on the presence of passengers to be transported. This study presents a volumetric analysis of the UPT situation in the Metropolitan Region of São Paulo (RMSP), examining the number of passengers transported between 2017 and 2022 by subway, urban rail, city and metropolitan bus systems, and individual motorized transport, revealing that the decline has been ongoing since 2017. The data illustrates the decrease in passenger volume during the pandemic and the gradual recovery in 2022, averaging 15% lower in the subway system, 28% in the urban rail system, 32% in the city bus system, and 20% in the metropolitan bus system, compared to 2017. In addition to underscoring the slow recovery of UPT, it underscores a shift in people's habits. In essence, the study provides an in-depth analysis of the evolution of passenger volumes in UPT in São Paulo during this period, shedding light on the challenges and prospects for the region's future mobility.
