This study investigates the opportunities that smart mobility offers as a fundamental part of the transition to a smart city. The study comprises a case study of the city of Taranto, Italy. The data collection was based on semi-structured interviews with policymakers with expertise in transport systems. Findings confirm the relevance of smart mobility as a primary fundamental factor to accelerate and begin the transition to a smart city, and how this transition requires a joint effort by both public actors and companies involving coherent, coordinated, and advantageous territorial development strategies aimed to achieve environmental sustainability and distributive equity.
