Hi HN! I wanted a way to visualize the MBTA system as a whole, so I hacked this together over the weekend.
It shows the current position of each bus, train, and subway, including a little tail behind each vehicle to show where it's been.
There are plenty of rider-focused experiences built around this data but I'm more interested in the visual aspect of being able to look at the whole thing at once. It's probably not a very practical tool for riders!
