With Citizen Datalab, Het Nieuwe Instituut & University of Sao Paulo. In the fall of 2016, we have organized two workshops in Sao Paulo in which we explored the performative affordances of urban data for citizen empowerment. This abstract theme will be made concrete through a focus on the role that the collection and representation of urban data can play to make Sao Paulo more ‘bikeable’. The project was announced by Mayor Van der Laan during his visit to Sao Paulo on June 19th 2016.
