Thread: Which order do the cars proceed at intersection.

The designer this must have been in a real **** stirring mood. Unless it has some historical significance, you would think a simpler intersection would have been designed?

Hhmmm. looking again at the Daytime video the Britannia Corner is very much like that & the Traffic certainly seems to flow well, albeit some in a reverse direction.


Shirley the Designers would have considered this but I think maybe there was lack of room to lay it all out.

Or maybe it was Professional egos?

I’m sure they did - and don’t call me Shirley!

Apparently it has been working well since 1972.

Have had the miss fortune to to navigate that round about a few times to visit a customer. If what they said is true it has an accident a day with the tow trucks parked in side streets waiting for clients. Experiencing the bedlam that it is can well understand why.

If the nose of your vehicle enters the roundabout first, and then another vehicle's nose enters on your right and honks you, you have not broken the law, and they have.

People do this every day here, they come barreling through at 90-100klm oblivious to the triangular giveway sign and 40klm/h speed sign. Its clearly posed. I regularly cruise in (legally) and force a conflict when im im the truck

Still I'm gonna give way to the right like I always have like everyone else does to me, try not giving way to a semi on your right and see what happens.
Obviously your gonna give way to someone already in the roundabout but what if your both there at the same time?

Both there at same time? If you are doing 40klm/h - you both go! Thats the bloody idea of roundabouts - even a modest sized one can have 2-3 cars at the same time. The big multilane ones can have 5-6 moving.

I played that vid of the swindon one at 0.25x speed on youtube a few times. One potential issue is that people can easily end up blocking other traffic. Just in that section of video there are a few dodgy occurrences, including a couple or so vehicles that go significantly over the give way line. The designers have the challenge of one of the roads being triple lane in each direction, plus there isnt actually a lot of space.

It seems the common modern solutions to having more than two roads crossing is to have a roundabout big enough for safe lane changing within the roundabout, like the one around parliament, or perhaps the more compact solution of having two roundabouts.

I would have thought one of the first things to do is to have a dedicated left turn only lane separate to the roundabout. Safely diverting all the left turners and keeping them out of the roundabout would seemingly take a percentage of heat out of the main roundabout.

Having dedicated left turn lanes transforms a three lane roundabout into a two lane roundabout.

Also, overhead signs advising people which is the best lane to start in for any given destination.

In Qld, it is give way to vehicles already on the roundabout, left, right or in between.
