Bikes, trains, busses, scooters, pedestrians, ... are all traffic.

Two of those are mass transit and the rest don't make very much noise.

50cc scooters are the worst, actually. Nothing like hearing the high-pitch squealing sound comparable to a leaf blower in your ear at 3am. I’d gladly see them banned from the city.
