Reply to comment by Die-Nacht in Traffic study by former head of NYC DOT reveals what he says is ultimate cause of congestion by HEIMDVLLR
So to reduce car demand you suggest... Eliminating roads?
That's the most backwards way to look at it that I can imagine. Why not knock down every residential building in manhattan to reduce rent if you're going down that route?

That wouldn't reduce the rent. It would reduce housing supply, which would reduce how many ppl can live there. And that's a bad thing. This is why rent is so high in NYC: housing supply is artificially kept low.
Reducing road space reduces road supply, which reduces the amount of driving, which in term reduces traffic. Which is a good thing. This is the opposite of "induced demand", which is a well studied phenomena

Why would reduced road supply reduce the amount of driving? In transit deserts (there are plenty of them in NYC), you need to drive to get anywhere.

If you are actually curious, there's a good amount of research on this. Here are some links from several different publications to get you started:
