This follows similar research performed in London last year. Thirty-two interviews with São Paulo grassroots organization leaders, their beneficiaries, intermediaries, and government officials were conducted over the summer and fall of 2017. Organizations interviewed included those that: led group walks and cycle rides in neighbourhoods perceived as difficult and dangerous; offered bicycle repair workshops; rendered public staircases inviting, rather than threatening, spaces; painted, or repainted, crosswalks/zebra crossings and bicycle lanes where they were needed but absent; and created phone apps for women walking at night to find each other. The initiative leaders interviewed led projects not only in the centre of the city, but also in peripheral areas of the north, east, and south zones. Site visits in the Paraisópolis favela uncovered the community do-it-together origins of alleyway (becos) concrete walking surfaces and street speed bumps (lombadas), the latter placed to slow down reckless motorcyclists traversing the neighbourhood. Now the Oxford DePICT team turns to follow-up interviews (i.e. member checks), focused analysis, and the production of outputs (policy briefings, journal articles, etc.).
