Uber has made anonymized trip data generated from over 2 billion trips in nine urban areas freely available for bulk download to help researchers, urban planners, and policymakers better understand transportation issues. The data includes average travel times between census tracts, and their equivalents in cities outside the United States, within a city, broken down by time of day and day of the week. Uber has made data available for Bogotá, Boston, Cincinnati, Johannesburg and Pretoria, Manila, Paris, San Francisco, Sydney, and Washington, D.C.
