I'm wondering if, with a big enough budget and a team of skilled devs like Dustin here, the local government could create more refined simulations to tackle these planning issues. Or would that inevitably run into the problem mentioned in his Project Mission: 'People are local experts on the small slice of the city they interact with daily -- the one left turn lane that always backs up or a certain set of poorly timed walk signals'?
Perhaps, with a large enough data pool, even these small quirks could be worked out via simulation?
