Walkability is a property of the environment that recently came to the fore in the context of urban planning and design. Its main aim in that context is to measure the “the extent to which the built environment is friendly to people who walk, which benefits the health of residents and increases the ‘liveability’ of cities..” (Wang and Yang 2019). My aim in this talk is threefold: Firstly, to show the fallaciousness of the planning/design approach to walkability as currently practiced. Secondly, to elaborate on the cognitive dimensions of walking and of walkability – specifically from the perspective of embodied cognition. Thirdly, to explore the implications thereof to the dynamic of cities as hybrid complex systems.
