SUMMARY:

This thesis aimed to identify and compare intra-urban mobility patterns using shared bicycles in four Brazilian urban centers (Rio de Janeiro, São Paulo, Porto Alegre, and Recife/Jaboatão/Olinda) during the second decade of the 2000s. Bicycle use has grown as an alternative to public transportation, whether for utilitarian, recreational, or work-related purposes, even in the face of structural limitations. In this context, shared bicycle systems emerge as a modern solution for active transportation, with the challenge of achieving intermodal integration in urban centers. The guiding research question was: considering the weaknesses in infrastructure and urban public transportation supply, what are the new mobility patterns and population flows of active transportation users in Brazilian urban centers? Three specific objectives were defined: 1) to analyze mobility patterns during the pre-pandemic, pandemic, and post-pandemic periods of Covid-19; 2) to identify connections between population characteristics, active mobility, and public transportation; and 3) to assess users’ perceptions regarding safety and well-being. Three hypotheses were tested: the pandemic significantly influenced mobility patterns, altering trip durations and flows; the availability of infrastructure and intermodal connections increases the use of bicycles; and users’ perceptions vary by region. A total of 59.1 million trips recorded by Tembici at 929 stations were analyzed, along with 271 responses from the Bike Barometer survey on cycling practices in three Brazilian regions. For the first objective, descriptive analysis and thematic maps were used with annual, monthly, weekly, and hourly data. For the second, data from the 2022 Census were used to correlate travel patterns with population density, the distribution of establishments, and the presence of public facilities. For the third, descriptive analysis of the Bike Barometer data was conducted, considering safety, comfort, and overall perception. The main results were: 1) a 7% increase in the number of trips after the pandemic, with an initial rise in average trip duration during the crisis, followed by stabilization; 2) a partial influence of household density, establishments, and public transportation on travel patterns; and 3) negative perceptions regarding safety, with reports of traffic conflicts, fear of physical violence, and accidents, with little regional variability. It is concluded that the pandemic temporarily impacted bicycle use, followed by a subsequent recovery. The infrastructure and surroundings of the stations partially influenced travel volume, while density indicators outside urban centers were not decisive for system expansion. Users’ perceptions were relatively homogeneous across regions, highlighting challenges related to safety and well-being. These findings contribute to urban mobility policies, supporting decisions regarding intermodality and the promotion of active transportation.
