Is This the End of Red Lights? - Comments Page 2

Freddy, KD and fbgcai- Roundabouts are only a short term solution. They will always reach traffic saturation point, and they definitely do not work in high traffic volume situations.

Have a look at Exit 16 on the M5 in the UK as an example. The roundabout has 3 lanes (4 in places) and sports no less than 8 sets of traffic lights. It is the only way vehicles can get on the roundabout, with traffic so heavy, it has to be stopped to allow this access. When you have to install traffic lights on a roundabout, the whole point of a roundabout is made redundant.

If you want an idea of the necessary upgrades to keep up with traffic volumes, Have a look here.

Road engineers will not admit failure. Absolute insanity.

Sounds to me like I can do anything I want in my DUMB car and the smart cars will all watch out for me.

What we are seeing is something I've heard called "Primary/Backup inversion". When we start relying on backup systems to do our job, but they are not perfect.
