What does it take to add real-time data for a new city?
I've been interested in trying to scrape the data from the transit provider here. They have what appears to be reasonably accurate arrival predictions which they display through an atrocious app, and electronic signboards at some bus stops. The busses have a terminal for the driver that displays how long they need to dwell at times stops and announces the next stop, so I assume this is (at an unknown interval) transmitting the locations to their server.
I haven't gone further in looking at it yet, because google maps will only add data sources directly from the official transit provider.
All excellent points. You're right we should have put more thoughts into our city roadmap. We basically looked up US city metro populations and went with that (how terrible, I know). With all the traffic and feedback we get now, it has become clearer which cities should have been prioritized (Miami and San Diego for instance were an absurd waste of time and resources). DC is definitely coming this week, followed shortly by Seattle and LA.
