Been working on a real time public transit app for the Bay Area and New York but recently decided to use the same data to create a visualization of all the transit vehicles moving in real time!
Initially wanted to make this before my app but it was quite a bit to process all the GTFS data. But now that the data is already processed for the app, the visualization was quite easy to make!
Currently trying to add geocoding so users can search for destinations for routing. Been interesting as I want to avoid Google Maps and other private data sources so open street maps it is.
