Active Mobility as a Sustainable Transport System: T-WSI evaluation in the Historical Center of Rieti (Italy)

This paper presents an evaluation of a neighborhood’s walkability using a validated tool known as the Walking Suitability Index of the Territory (T-WSI). The analysis was conducted in the Historical Center of Rieti, Italy. Each street segment was assessed based on 12 indicators subdivided into four categories: practicability, safety, urbanity, and appeal. The final T-WSI score was 51.71 percent, with a large variability of scores between the examined streets (min – max: 20.9 – 88.43 percent) across the area. Low scores were mainly associated with inadequate green spaces and sidewalk facilities. Results suggest that strategies prioritizing active mobility, such as the provision of standard infrastructures and designated car-free zones, could enhance walkability. These findings support the use of T-WSI in the development of regeneration projects for historical ruins.
