<p>Smart mobility, defined by the use of sophisticated digital technologies into urban transportation systems, provides significant advantages in efficiency, sustainability, and safety. Nonetheless, its dependence on interconnected networks and real-time data processing has created considerable cybersecurity concerns. This study analyzes geographical disparities in cybersecurity threats to smart mobility systems, assesses adaptive mitigation techniques, and provides a complete framework to bolster cybersecurity resilience. A systematic literature assessment of 56 peer-reviewed studies identified significant disparities between developed and developing regions. Developed nations confront complex threats include malware, denial-of-service (DoS) assaults, and data breaches, whereas underdeveloped regions grapple with basic difficulties stemming from insufficient infrastructure and disjointed regulatory frameworks. The research delineates essential adaptive strategies, such as blockchain for secure data transmission and AI-powered intrusion detection systems, as efficacious measures to mitigate these risks. Nonetheless, scalability, interoperability, and regulatory deficiencies persist as substantial obstacles, especially in resource-limited contexts. The suggested framework amalgamates regional threat assessment with adaptive strategies, highlighting public–private partnerships, strategic investments, and cohesive regulatory standards. The study enhances the field by systematically categorizing cybersecurity threats and solutions, presenting pragmatic policy recommendations, and pinpointing research deficiencies for future investigation. The findings, mostly derived from secondary sources, highlight the essential requirement for empirical validation and interdisciplinary strategies to tackle the changing cybersecurity scenario in smart mobility systems.</p>
