São Paulo starts tech-driven plan to improve transport system

The São Paulo city government will use open data and a skilled crowd of techies to try and improve its precarious public transport network.
São Paulo’s metro network is efficient but small, with only 74km of track compared with 337km of track in New York City. As a result, the roads are packed full with buses – and car ownership in Brazil rose 32 percent to 7.4 million during the past decade, which partly explains why São Paulo is often nicknamed “the city of 19 million traffic jams.”
