M5-Pontiac Trail-Martin Pkwy Roundabout
I know a lot of ink has flowed writing about this big, and poorly functioning roundabout, BUT, as a frequent user, it's pretty obvious to me what isn't working on it. I'm a huge fan of roundabouts and the main thing is that all traffic flowing in has to slow down! Yes, to slow down, not drive near-freeway speeds into it. The cars arriving from M5 are going too fast....they need to slow down to 15 mph or even less. But instead, decision makers put a screen up to block and slow incoming traffic from Pontiac Trail even more. Bad false solution! That's the opposite of what is needed: PT traffic coming west was already going slowly and the point of a roundabout is to see what is coming so you can go, not to block the view, which will just get some drivers pulling out without seeing. My suggestion would be to do something to slow the incoming from M5, such as speed bumps, starting 100 yards or more from the intersection. If not speed bumps, you could make the road snake back and forth or something. In any case, that roundabout would IMO work flawlessly if all cars arrived slowly. The problem is that the other lanes can't get out because M5 arrivals are going 30 mph or more. Anyway, thought I'd put this out there for anyone interested. Drive safe!
