It was anticipated that the so-called “Mobility 4.0″ would introduce modifications to transport systems that could potentially influence mobility conditions provided by existing modes of transport. Nevertheless, it remains unclear how these changes will impact mobility in terms of its sustainability. This gap is particularly evident in countries such as Brazil, where this research was conducted. This study evaluated the prospective implications of selected mobility 4.0 developments (in particular, electric and autonomous vehicle technologies, and shared mobility) by examining 18 themes related to sustainable urban mobility. An online questionnaire was designed and distributed to professionals in the field. The questionnaire sought to categorize the most significant impacts within each theme using a 5-level Likert scale, ranging from very positive to very negative. Data analysis extracted from 320 valid responses provides empirical evidence that helps identify these technologies’ potential impacts on urban mobility’s sustainability. Depending on the theme, these impacts may be positive, negative, or neutral/undefined. It is noteworthy, for example, that electric vehicles and shared mobility have been evaluated very positively in relation to the theme Control of impacts on environment, which falls within the Environmental aspects domain. Overall, the level of knowledge demonstrated by the respondents did not significantly impact the results. However, when observed, this characteristic was notably marked among the respondents with advanced practical knowledge. Finally, in terms of policy recommendations, the outcomes suggest that policymakers must be prepared to constantly adapt policies based on changing technology, user behavior, and urban dynamics. Moreover, potential discrepancies in access to distinct socioeconomic groups are also a concern that must be addressed by policies, as these groups may have differing needs and expectations.
