Especially cast in ashphalt, with officers to enforce it......... :worried:

Reminds me of the Illuminatus! explanation for the Pentagon...

Magic Roundabouts
 

They're a bit like crop circles I'm afraid - another one has turned up on London Heathrow Airport South Perimeter Road by the east exit..... on the same ley line as the Swindon Roundabout some 30 miles west, or so I am led to believe...

The jughandles replaced traffic circles in some cases.

People in New Jersey are, according to people in Pennsylvania, notoriously bad drivers.

We have the jughandle thing going on in Pennsylvania also. for some intersections they are very helpful. Unfortunately PennDOT keeps adding new ones to old, perfectly good intersections, screwing them up.

I have absolutely no problem apologising (sorry 'apologizing') for the teletubbies - please send them back as I know exactly where they may be re-sited (if I can find the inventor). Pls may we have the answer now?


Further apologies from ignorant Brit, but only know jughandles to be just that - pls elaborate and educate...

Like this ...

You're not allowed to make your left hand turn at the intersection.

You go into the jughandle, and then turn left out of it.

This will make more sense if you remember that Americans drive on the right.

Sometimes there are extra traffic lights so you can actually turn left out of the jughandle into traffic. Sometimes there are not ... which is when jughandles become more dangerous than the old-style left turn lane and light at the intersection.

Other ones are set up so you are only making right hand turns.

You don't always know you're in a jughandle area ... the signs don't say "jughandle ahead" ... they say "all turns from right lane."

In this particular example, jughandle #1 would be for people who are turning right on the cross street ... jughandle #2 is for folks that want to make the left ... which now involves two right turns.

you'd turn left from the jughandle rather than turn right from the main street? how does that save time/congestion?

Thanks Wolf - this has left me somewhat in awe of your road research gurus. Initially it looks like a good idea but then the designers get carried away. Isn't #1 for turning left though, and #2 for turning right?

Any incidents of a double jug-handle, where say, as in #1, there is a return handle so that the motorist who mistakenly turned right when he didn't mean to has another handle to his left (placed a short way along after entering the first handle) which pemits him to return to the original highway but a little further on....... just an idea....

I don't mind jug handles, and actually was made fun of for years because I would pull into a parking lot and then use the light at the exit to cross over onto my moms street - making my own jug handle, and avoiding sitting at the light for 12 years in Delaware county traffic trying to make a left turn. A better option: a left turn arrow. Seems like an extra bulb on the traffic light would be cheaper and easier than all that extra pavement, but what do I know... We don't have traffic out here in Elverson, much less traffic circles.

Like this, mrnoodle:

There's also 3 way stop jug handles which I encountered.. :rolleyes:

I see access to the jughandle somewhat differently, based on the shapes of the "exit ramps". The purpose is so only straight through traffic crosses the intersection.

Isn't this what you're really trying to achieve?

OK so my double jug handle was a bit hard to follow, so here's a graphic (sorry it's an attachement but I haven't worked out how to import a picture yet!):

And another to show how the Magic Roundabout 'works'

I have round-abouts in the neighborhood I just moved into and it's a brand new area. I don't get the idea as to why they think this is a good idea, I hate them.

This is a typical layout of one just down the street from me, and a typical negotiation of one.

1) Car 1 comes to the round-about slows but doesn't stop.
2) Car 2 comes to the round-abut slows but doesn't stop.
3) Car 1 doesn't see car to decides I...err...he doesn't want to drive all the way around and cut the wrong way.
4) Car 2 presses on, vision restricted due to folage in center of roundabout.
5) Both cars stop and glare at eachother with distain
6) Option: Postion where firey crash occurs when both cars see eachother and try to beat eachother out anyway.
