Creating accessible, safe, and vibrant environments that accommodate all modes of transportation, particularly walking and biking, is fundamental to the development of urban spaces. Active transportation modes are crucial not just for the physical infrastructure of a city but also for the well-being and engagement of its community members. This guidebook recommends strategies for enhancing the attractiveness and viability of walking and biking that are particularly effective within the context of Detroit. The City of Detroit is already taking steps to encourage active transportation, including initiatives such as the Zoning Analytic, Streets for People Plan, and Streetscape Projects. But what is still missing? What aspects are working well? Are there additional methods that could amplify the effects of these current projects? Understanding these questions will emphasize the importance of supportive development, evaluate the potential to increase opportunities for active transportation in Detroit, and provide insights for replication in other cities. The report includes an assessment of Detroit's ongoing initiatives and a targeted site visit to the Avenue of Fashion, enhancing our understanding of how walking and biking promotion act within the local context. It provides a versatile "Toolbox" of strategies that allow planners and advocates to pull from a set of options to best fit a particular situation, thus promoting active transportation in a manner that respects and responds to Detroit's diverse urban fabric.
