<p>Smart mobility, an essential component of long-term global development, has the potential to transform city design, logistics, and the movement of commodities and people in the face of increasing demographic expansion. By shifting from traditional transportation systems to mobility as a service, smart mobility integrates digital infrastructure to link stakeholders, providing efficient, sustainable solutions while minimizing environmental effects. The present paper focuses on the impact of smart mobility solutions on urban transportation efficiency in Saudi Arabian cities within the context of Saudi Arabia’s Vision 2030 and its sustainable development goals. A survey questionnaire was used in this study to assess public perceptions, satisfaction, and concerns about the adoption of smart transportation solutions. The findings show a considerable public willingness to embrace technologies such as smart buses, ride-sharing applications, and e-scooters, with 77.8% of participants eager to use smart mobility for daily travel. However, responses reveal serious problems, such as poor infrastructure, a lack of public awareness, and excessive expenses. These constraints highlight the importance of strategic infrastructure improvements, focused public awareness efforts, and economic modifications in order to make smart mobility more accessible and successful. Future policy and planning must address these concerns in order to fully realize the benefits of smart mobility solutions, promoting more fair, efficient, and sustainably friendly urban transportation networks. The present paper provided recommendations to encourage wider adoption and optimization of smart mobility systems, assuring alignment with public requirements and contributing to the overall aims of sustainable urban development.</p>
