Very impressive. Also interesting that the motion type prediction ("is this a moving train?") generalizes to underground trains in other cities.

I see they support the the largest cities in Sweden and Norway, wonder if there are any plans for Copenhagen, Denmark?

While I understand your question is about the Transit app in general, I'd just like to mention in correlation to the article that my team and I worked with one of the public transport operators in Denmark, to utilize the motion predictability feature found in Android and iOS SDK's, so I can enlighten you with some details regarding that.

Our conclusion was that the feature didn't work in the danish metros for reasons we never got to deep dive into. It's most likely related to the fact that many of the metro stations are built in concrete, as such there's no GPS data in most of them unless you're very close to or on the surface and no motion data.

I'd be surprised if they got this particular feature working but who knows... maybe if we had looked into the raw sensor output we might have been able to work something out.

In the end we made a solution to help determine when you're moving or not by utilizing beacons.

How come there's no motion data?

Let them know you’d like CPH !

Especially if you know someone at the transit agency or can help them even in a very small way.
