Investigate Walkability: An Assessment Model to Support Urban Development Processes

This chapter is about defining and testing a multi-methodological frame- work able to measure the “walkability” in the urban practice perspective, based on assessment indicators and Geographic Information Systems (GIS). Nowadays, cities are facing a complex challenge concerning sustainability, which is fueling the search for new development solutions. Among others, one of the most important problems is how to make cities sustainable and resilient, as stressed by the Sustainable Develop- ment Goal 11 (SDG11) highlighted by the United Nations through the 2030 Agenda. The topic of “walkability” appears in this framework: Walking has ecological, social, economic and political benefits. Moreover, designing walkable networks is impor- tant to create a functional and multi-modal city with transport choices and makes urban settlements sustainable and inclusive from the perspective that a sustainable city is also a walkable city. However, despite the positive impact of walkability on public space, it is still difficult to fully include it in governmental strategies because of its novelty in the scientific debate. The ongoing research proposed here aims at: (i) describing the problem, related to what trends and strategies have been implemented to face it; (ii) investigating walkability, understanding its definition in the scientific panorama, and how it is evaluated; (iii) understanding the current evaluation methods to assess the walkability of spaces; (iv) proposing a new multi-methodological frame- work based on existing methods that are able to measure the walkability degree from the perspective of better planning of cities. The multi-methodological framework has been tested through a case study: the Politecnico di Torino Campus (Torino, Italy).
