You asked "hypothetically what would work". There is no need for hypotheticals, since we already know what works. That debate ended years ago, and you seemed unaware of this fact, so I was letting you know.

If you have questions on how specific situations are handled, you now know that other cities are doing this already and can go learn about how they did it. If you're still asking random ppl on reddit, I'm going to assume you aren't really that interested and are just killing time at work or something.
