Designing Urban Spaces to Enhance Active and Sustainable Mobility: An Analysis of Physical and Symbolic Affordances in School Squares in the Metropolitan Area of Milan, Italy

As thresholds to cities, public spaces adjacent to schools play an important role in children’s everyday mobilities, potentially shaping their future mobility habits and affective experiences. The purpose of this paper is to investigate the urban design conditions of such spaces, defined as “school squares”, and, with the aid of affordance theory, to analyze spatial features and characteristics that might encourage or hinder active and sustainable mobility practices. In the first part of the paper, we define sustainable mobility, conduct a literature review on affective responses to the urban environment, and discuss active school travel (AST) in relation to the design of school squares. By focusing on 416 primary and lower secondary schools in the metropolitan area of Milan, we present an assessment method that is composed of on-desk and on-site surveys. In particular, Phase 1 defines the type of school squares, Phase 2 investigates physical affordances (spatial features and characteristics that directly influence active mobility practices, such as bicycle racks, protective barriers, benches, and parked cars), and Phase 3 discusses symbolic affordances (elements and characteristics that might induce different affective responses to a school square with regard to active mobility, such as bicycle racks, parked cars, greenery, and dustbins). The results indicate that in most cases school squares are characterized by typological confusion that has nothing to do with the school environment: narrow sidewalks, disorder, and low levels of safety. In order to promote active and sustainable mobility choices and enhance children’s mobile experiences, it is necessary to address the aforementioned features. The ultimate goal of this paper is to provide insights for developing an urban regeneration framework that considers school squares a safe context and a starting point from which to perform sustainable mobility practices.
