I doubt that traffic data was their main issue ... but anyway ... yes, traffic data is a difficult topic. And yes, the state of open traffic data is bad: https://github.com/graphhopper/open-traffic-collection https://github.com/graphhopper/open-traffic-collection But no, although Google and Apple (and also Mapbox!) do not give a away their traffic data, there are still three sources for world wide traffic data: TomTom, HERE and inrix. All acquire their data via external software companies or automotive companies (or whatever) including their measurement units into their products. Mapzen was starting their open traffic data project and so we at Graphhopper were hoping they would solve this issue in the next years, but now, obviously they won't: https://twitter.com/mapzen/status/940710887068860417 https://twitter.com/mapzen/status/940710887068860417 https://github.com/opentraffic/otv2-platform https://github.com/opentraffic/otv2-platform
