google has waze which i presume sends high-g events like sudden braking to a central collector somewhere.
waze is how their maps product knows where the traffic is on surface streets.
- astrange 10y agoMost maps products get traffic data from the same external vendors (like TomTom). I think they get it from dedicated sensors like counting cars on street cameras. Obviously you see Waze info on Waze itself but it has to work without any other users nearby. (Btw I don't think Waze and Google really share all their data, Waze doesn't even have lane routing.)
- Piskvorrr 10y agoThere seems to be a mix of both - Waze-collected data seems to be fed back into Waze, but there seem to be other sources as well.
