From what I've been reading, that's the recommended way, and it would reduce the amount of reported errors, while still not allowing WAZE to route commuters down those roads. Or can WAZE still route to a private road?
You got it. Due to the significant time savings from the rapid transit line, Waze would likely route you down there when it made sense, despite it being marked as a private road. That is why I disconnected it, so I that I could remove any chance of Waze attempting to route someone down there. As far as those error message go, I quit hitting resolved. I even placed something on there telling people not to use Waze on the bus, but people still continue to do so...
For the downtown bus route, the intersections have no turns allowed at all, why not allow the bus route to go straight through, but keep the intersecting roads from turning on to it?
Take another look at it, from what I'm looking at, that's exactly how it is setup. Cars aren't supposed to travel down parts of Graham. In order to increase the penalty associated with the route, I changed the segments to private AND disabled all turns arrows applicable exclusively to the buses. The arrows are still enabled, although traffic to travel north and south bound streets that travel through Graham.
