Improving Walkability for Sustainable Mobility and Urban Regeneration in Rome

In historical city centers, walking is a natural and appealing activity, while contemporary districts designed around cars often lack landmarks, social vibrancy, and appeal, promoting car-dependent lifestyles. Urban literature highlights successful district regenerations that prioritize walkability, aiming to shift modal preferences toward non-motorized modes and foster healthier living, with the vision of a “salutogenic city” driving these efforts. However, assessing walkability in unattractive built environments poses challenges. To address this, a methodology was applied to three Rome districts, quantifying walkability using a composite index based on 12 indicators across four categories: functions and use, safety, urbanity, and attractiveness. Scores were derived from direct observations, providing a reliable snapshot of walkability. This approach also facilitates long-term assessment, evaluating performance changes due to repurposing or regenerative interventions. Tested in diverse Rome districts, the methodology not only quantitatively compares scores but also reveals increased walkability in a regenerated district. Notably, safety and attractiveness improvements were attributed to vegetation management, architectural barrier removal, and enhanced road safety.
