I think the solution, at least where you create everything, is buses that go non-stop between major hubs. And with traffic lights synchronized to allow them to hit their top speed. And, where possible, set the speeds high. If every spoke is timed so it takes the same amount of time, you can minimize how long people have to wait. Make everybody get on at one end of the bus and exit at the other and hub stops can be short. You'd have to walk to the nearest hub and from the one closest to your destination. But you need the exercise anyway. And charge tolls for passenger cars that vary with demand, something that would work without recreating the roads.
