How walkable is the city? Application of the Walking Suitability Index of the Territory (T-WSI) to the city of Rieti (Lazio Region, Central Italy).

A method to evaluate the walkability of an urban neighbourhood based on direct observation has been applied. This tool, called the Walking Suitability Index of the Territory (T-WSI), measures the walkability of every street of an environmental area. It includes 12 weighted indicators, each divided into 4 categories: practicability, safety, urbanity, and pleasantness. Each indicator can obtain one of the following values: excellent (100), good (75), poor (35), bad (0). T-WSI is applied to 12/15 urban neighbourhoods of Rieti, a small city (47,912 inhabitants) located in Lazio Region (Central Italy). The average of T-WSI scores range from 24.2 to 61.2 among urban neighbourhoods. On average, safety and urbanity are the categories which reach very low scores. The T-WSI allows to underline several street criticalities that could hinder walkability and could be a good basis to support public decision-makers about health policy and local development aimed at encouraging physical activity.
