Wow, first of its kind? How does that happen? With so many people riding the NYC subway, I’d have expected this role to have been filled multiple times. Great job!
Thanks! The data that drives this wasn’t available until 2018. Since this is a uniquely NYC problem, 3rd party apps by companies based elsewhere don’t recognize that this a problem that needs to be addressed. MTA eventually released their own version a year after I did, and there’s at least one other 3rd party app that I know.
