Quote from: Schmengie on November 30, 2010, 02:43:31 pmA moving van can't make it through one of our little mini-roundabouts without going up the curb on one side or the other. Both of them are on major thru-roads in this town and are often impossible to avoid for delivery vehicles big or small. Road planning? WTF is that?? Here's the newest one, on Pleasant Valley Rd. just a few blocks from my place. (Courtesy of Google Earth Streetview). It actually looks bigger in this pic than it really is. It looks to me like that inside curb is designed to be high enough to discourage cars from cutting the corner, yet low enough for a tractor trailer or large van to put a wheel over without issue. I know that's how they designed the one here.Any idea what the planners have in mind for the middle of that roundabout? The geniuses around here decided to build ours up with a bunch of huge rocks and some trees - very pretty, but now you can't see (and plan ahead for) oncoming traffic entering the roundabout.

Is that what you're saying?If that's what I was saying, don't you think I would have said that. Roads are designed primarily for cars. Trucks take wide right turns, but we don't design every intersection to be overlarge to accomodate them. You design the road to handle the needs of the average vehicle. That's why we have truck routes. Because not all roads are designed to handle truck traffic.

Those curbs are designed to be driven over by large vehicles. Sometimes ( never seen one in Canada) they have rumble strips to warn the driver that they are using some of the centre.
Went through our big roundabout in Orleans this weekend, whoopie do, in and out in 2 seconds not sure what the fuss is about. Works great and very easy to navigate.
Massasschusetts have a bunch of those traffic rotaries (proper U.S. terminology) too.
Interesting article in the NYT about the increasing use of roundabouts south of the border.

I just went though a roundabout in Lasalle, Ont and in the middle of it it was a landscaped hill with trees and shrubs. Because of the height of the hill, it severely cut down on how much of the total roundabout could be seen. IMO, the center of the roundabout should be flat so you can see all the way through it. Am I nuts for thinking this?
That's a tough one. Really, anyone entering a roundabout should be looking left, and shouldn't be concerned with looking straight ahead. However, I'm with you on the height of the centre" Keep all the landscape and ornaments out of it.
