How can you say with any confidence that the unknown unknowns you have won’t be very hard to work around? That’s entirely the point of unknown unknowns - you do

(Shrug) I know how to figure out where some subway cars are and keep track of them for less than nine figures. I don't expect anyone to take my word for it, and I don't care if they don't; it's just an excuse for some meaningless chest-thumping on HN while waiting for Vivado to do its thing. :-P If I lived in New York and had to pay for it, I'd probably find the question less interesting and more infuriating.

  I would encourage you to submit a problem statement with your proposed method to TCRP research program [0,1]. Unfortunately the 2019 solicitation is closed, but the 2020 solicitation will open early next year. A better vehicle tracking method than the current block-level tracking is something that would be valuable to sub-surface transit system in the USA and if what you propose (or something similar) is feasible, the statement stands a real good chance of getting funded for a research project. And if the project is funded, you can even bid on the research work. I'm active on the TBR ADC040 subcommittee, if you have questions, hit me up (my twitter is on my profile) and I'll see if I can connect you to the right person. I write this in all seriousness - this isn't a "if you're so smart why don't you do it" post, I'm writing this in acknowledgement that there are a lot of smart people on HN, and if there's a chance to improve US transit, I'm all for it.

    I hear you, but unfortunately, I have no insights that any random EE (or advanced hobbyist) with some DSP experience wouldn't immediately bring up as well. It's safe to say that anything I could suggest has already ended up in plenty of proposals. It would be interesting to understand just why this is considered a $100M-$1B problem, though. I'm curious enough to do some more reading.
