About a Roundabout

Don't forget about downtown Detroit, the roundabout surrounding Campus Martius may be oblong in shape but its still a roundabout.

I don't think that is considered a roundabout because it has traffic lights. It's just a circle drive.

[Joseph C. Krause]

I think a roundabout is overdue for the intersection of Trumbull, MLK and Grand River.

Roundabouts can have traffic lights. There are a number of roundabouts in Britain that do. These are usually found at freeway entrance and exit ramps to/from very busy highways. The lights only operate during times the traffic volume overwhelms the roundabout.

Roundabouts can be overwelmed by bumper to bumper, stop and go traffic.

The lights at CM are only really needed for pedestrains. CM would function fine as a regular roundabout.

Roundabouts are becoming much overused as of late. Some college must be advocating it in their Civil Engineering course. They are appropriate in limited applications, namely when you have several roads converging at one point, like you will find in Paris or Washington, DC. For a four way intersection, they are a waste. For a five way, they can usually offset the fifth road.

wolverine is right. We all must be trendy now, and justify our need for a portion of "stimulus" dollars.
