Be careful about infringing on existing intellectual property as you re-invent the wheel. There are solutions out there for micromanaging truckers.
I don’t know what system Dallas is using to track the streetcars and send the data to the app.

I take it that you are looking for a cheaper solution to undercut the expensive guys.
Thanks. Looks very interesting. I’m not looking to “undercut” anyone. This isn’t designed to track vehicles, but to aggregate data and measure performance for the fleet as a whole over long periods of time.
