Shared mobility during public transport disruptions: Users’ perspectives in a Brazilian city

• Ridesourcing is recognized as an alternative mode during disruptions. • Unfamiliarity, infrastructure, and safety affect the viability of bike sharing. • Equitable bike stations, safe infrastructure and trial incentives are needed. This study investigates the potential use of shared mobility systems during public transport disruptions. Unlike most studies in the field, our approach focused on users’ perspectives, based on a joint revealed preference/stated choice survey with over 1,000 respondents in Rio de Janeiro, Brazil. Spatial analysis and logistic regression reveal that proximity to bike sharing stations, young age and private vehicle ownership increase the chances of shared bikes use. Mixed logit model estimates with stated choice data show cost sensitivity variations among users when choosing between ridesourcing and public transport during disruptions, with proximity to public transport infrastructure favoring ridesourcing as a possible complementary mode. The results highlight the potential of ridesourcing during disruptions, with a high willingness to pay for time savings. In contrast, bike sharing is not considered viable for commuting during public transport disruptions due to unfamiliarity with this service and concerns about traffic and safety.
