Major problem: if any vehicles of any kind are parked or stopped on the transit streets traffic will come to a complete standstill. There are already several choke points on the streets that are marked as out from town and in from town on the diagram. For this to work there can be no parking of vehicles (or stopping) on Back Street, the street by My Secret Deli and the street in front of El Fogon. Plus, all northbound traffic has to cross in front of southbound traffic at the roundabout and all southbound traffic has to cross in front of all northbound traffic by Varella's. Unless you put traffic lights in there's not a chance that it will work. Nice idea but highly impractical. One other thing, students and bicycles will also need to learn how to walk/ride in single file and that will never happen.
