Daily commuting characteristics were highly affected by the COVID-19 pandemic, since restriction of the movement of people was one of the main preventive measures adopted. Understanding of the effects that the pandemic had on mobility is essential to help in mitigating the problems arising from this crisis, while also providing an opportunity for the implementation of sustainable policies in the post-pandemic period. Therefore, the aim of this study was to identify the impacts of the pandemic on the profile of travel behavior and mobility preferences in Brazil, using a case study of cities located in the state of Rio Grande do Sul. The data obtained from an online survey were modeled using exploratory factor analysis, resulting in the extraction of 15 main factors that explain behavioral changes in mobility due to the effects of the pandemic, as well as future perspectives. In the pandemic period, the use of private vehicles grew as the main mode of transport to the principal activity. Conversely, the use of public transport decreased drastically, due to compulsory measures taken by the health authorities to prevent the spread of the new virus. There was also greater receptivity to the adoption of active mobility, especially the bicycle, although it is necessary to provide better conditions for use of this transport mode. The findings support the development of public policies to reduce urban mobility problems and to provide guidelines for sustainable planning in the post-pandemic period.

日常通勤特征受到 COVID-19 大流行的严重影响，因为限制人员流动是采取的主要预防措施之一。了解大流行对流动性的影响对于帮助缓解这场危机引起的问题至关重要，同时也为在大流行后时期实施可持续政策提供了机会。因此，本研究的目的是通过对位于南里奥格兰德州的城市进行案例研究，确定大流行病对巴西旅行行为和出行偏好的影响。从在线调查中获得的数据使用探索性因素分析进行​​建模，结果提取了 15 个主要因素来解释由于大流行的影响而导致的流动性行为变化，以及未来的展望。在大流行期间，私家车的使用增长为主要活动的主要交通方式。相反，由于卫生当局采取强制措施防止新病毒传播，公共交通工具的使用急剧减少。尽管有必要为使用这种交通方式提供更好的条件，但人们也更愿意接受主动出行方式，尤其是自行车。调查结果支持制定公共政策以减少城市交通问题，并为大流行后时期的可持续规划提供指导。由于卫生当局为防止新病毒传播采取强制措施，公共交通工具的使用急剧减少。尽管有必要为使用这种交通方式提供更好的条件，但人们也更愿意接受主动出行方式，尤其是自行车。调查结果支持制定公共政策以减少城市交通问题，并为大流行后时期的可持续规划提供指导。由于卫生当局为防止新病毒传播采取强制措施，公共交通工具的使用急剧减少。尽管有必要为使用这种交通方式提供更好的条件，但人们也更愿意接受主动出行方式，尤其是自行车。调查结果支持制定公共政策以减少城市交通问题，并为大流行后时期的可持续规划提供指导。
