    It has always been my understanding that traffic patterns on mapping software is derived from cell phone traffic.

    If that is the case, why do we never (or do we?) see moving trains on maps?

    I would LOVE to be able look at my map and know which route to take based on train traffic as well.
    Especially freight trains.

    If two routes exist, one at level, one with an overpass.

    I can think of one reason not to do that: security.

    Google uses phones, as does Waze, owned by Google. But many of the proprietary car navs used their own radio derived traffic signals from traffic reporting services. I think Google is the best. I wish that Tesla would fully integrate Waze, which would the best.

    Great question!

    I wonder how Google differentiates between phones moving in cars vs other modes of transport (trains, bikes, fighter jets...)

    Um... perhaps it as simple as the fact that Google knows where the train tracks are and discards that info
