The perfect Traffic Light Graphic example...

For those of you from the other side of the pond who don't feel too comfortable with roundabouts, I'd suggest you avoid [url = http://en.wikipedia.org/wiki/Magic_Roundabout_%28Hemel_Hempstead%29]this one[/url] if you visit the UK.

In Southern California we simply called it "The Circle". It worked as it should. At least it did when I was in High School ( some 50 years ago) I'm sure somethings have changed a little by now though.

They build one locally Palmdale ,Ca., it tuned out to be a joke it's simply to small.

Take a look at the roundabout in the pic. It shows that every entrance to the roundabout has traffic lights on it. These lights are working 24/7/365, and as you can see it was pretty deserted when the photo was taken. In fact I know it is like this for MOST of every workday, and ALL of a weekend.

I estimate that the regulatory lights are only needed for say 2 hours on a weekday morning, and similar in the evening (the so-called "rush-hour"). That means they could be switched off for 158 hours a week, and consequently save us some energy !!

I think the Magic Roundabout in Swindon UK takes the prize for the most complex !

Easiest way to make a link is to copy the URL from your browser bar to the clip-board (Ctrl-C), then in your posting, highlight the text you want to be a link, hit the Insert Link button in the posting editor (middle, bottom row), and paste (Ctrl-V) the URL into the dialog that pops up.

Roundabout, what is that?

There are very few roundabouts here in the US. I was amazed to see those in London and people getting through intersections just dandy without stop signs or stop lights.

We have a few around here but it is called a rotary.

If you want to see roundabouts get yourself over to Milton Keynes, there is a roundabout every 100 yards.

Most of the roads are called V1, V2, V3 etc and H1, H2, H3, etc.. The V meaning vertical as in north to south and the H meaning horizontal as in west to east.
