How do we accommodate a growing urban population in a way that is sustainable, equitable, and inviting? Jan Gehl has been examining this question since the 1960s, when few urban designers or planners were thinking about designing cities for people. But given the unpredictable, complex and ephemeral nature of life in cities, how can we best design public infrastructure—vital to cities for getting for place to place, or staying in place—for human use? Studying city life and understanding the factors that encourage or discourage use is the key to designing inviting public space. In How to Study Public Life Jan Gehl and Birgitte Svarre draw from their combined experience of over 50 years to provide a history of public-life study as well as methods and tools necessary to recapture city life as an important planning dimension.
