While numerous studies have examined these phenomena, there is still a need for empirical evidence that not only documents what occurred but also provides actionable insights for future transport planning. This study aims to enhance understanding of public transport passengers\u2019 mobility behaviors during different stages of the pandemic, using the Metropolitan Area of Porto, Portugal, as a case study. Automated Fare Collection data from 2020 were analyzed and compared with data from the pre-pandemic year of 2019. The analysis included temporal, spatial, spatio-temporal, and sociodemographic dimensions. Key patterns and trends identified include a rapid recovery of ridership post-restriction easing, homogenized daily travel patterns, varied impacts on different transport modes, and significant shifts in demographic travel behaviors. These findings highlight the resilience of public transport demand and suggest that adaptive scheduling, enhanced safety measures, targeted support for vulnerable groups, promotion of off-peak travel, investment in bus infrastructure, and encouragement of multi-modal transport are essential strategies. Implementing these strategies can help improve public transport planning and mitigate the adverse effects of future crises.<\/jats:p>","DOI":"10.1186\/s12544-024-00673-x","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T09:01:46Z","timestamp":1728378106000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Understanding the impact of COVID-19 on mobility behavior of public transport passengers: the case of Metropolitan Area of Porto"],"prefix":"10.1186","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9505-5730","authenticated-orcid":false,"given":"Marta Campos","family":"Ferreira","sequence":"first","affiliation":[]},{"given":"Hugo","family":"Fernandes","sequence":"additional","affiliation":[]},{"given":"Thiago","family":"Sobral","sequence":"additional","affiliation":[]},{"given":"Teresa Galv\u00e3o","family":"Dias","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,10,8]]},"reference":[{"key":"673_CR1","doi-asserted-by":"publisher","first-page":"1199","DOI":"10.1056\/nejmoa2001316","volume":"382","author":"Q Li","year":"2020","unstructured":"Li, Q., Guan, X., Wu, P., Wang, X., Zhou, L., Tong, Y., Ren, R., Leung, K.
