Abstract : This study aimed to construct and assess a pedestrian walkable network that would be used further to generate an analytical lens for the assessment of community walkability across the City of Toronto. In this study, we dealt with proximity analysis of pedestrian network in Toronto city by visualizing how “walkable” a destination is, in terms of access to different amenities like schools, libraries, hospitals, supermarkets, TTC stops and convenience stores. The basic approach of this study is first to create pedestrian networks as graphs of links and nodes, then calculate walking distance and minutes based on the accessibility of various amenities via pedestrian sidewalks networks and analyse pedestrian walkability. 20-minute neighbourhoods walkability has been calculated to determine how-walkable a particular area is in relation to pedestrian access to various amenities and socio-demographic characteristics. The overall result gives an overall walkability score or allows users to know if a given neighbourhoods are more walkable within 20 minutes. These analytical results provide policy opportunities for city planners to pursue strategies to encourage the development of more walkable (pedestrian friendly) and to improve accessibility to meet the needs of its users. This study details an analytical approach to measure 20-minute neighbourhoods with the aim of supporting city wide policies to identify opportunities to design more liveable 20-minute neighbourhoods.
