No more traffic jams?

This makes sense to me.  I hope it is legislated.  I detest tailgaters.

Yeah, it makes sense alright.

Most people don't follow road rules, though, so I doubt it'll work.

Theres a lot of roadworks for me at the moment to contend with. Essentially out of the suburb I live in to get to main part of Canberra I work in there are 4 decent roads I can use. 2 are currently undergoing duplication and a third is having the tram put on it. Traffic jams every day.


I think this has merit, but also the other issue is people who try and get around the jam currentl;y by driving through an empty suburb and rejoining furhter down. It backs traffic up more because people stop to let them in.


Its also affecting the cycling. I don't like cycling on the roadwork sections because theres not enough room for my bike and for cars, and they are progressively blocking all the paths I can use to go home with.

You would have to change driver behavior somehow and it would never work because drivers are basically selfish.

Back in the late 80s or early 90s on Canterbury Rd in Melbourne they had a trial where they installed all these variable speed signs. The idea was that if you kept to the speeds displayed you would get green lights along the entire length of the road.

The problem was that in many instances the speeds displayed were well below the actual speed limit. As a result people ignored the variable speed signs and the trial was abandoned.

This has nothing to do with congestion on your daily commute. It's just about those phantom traffic jams in the middle of a long stretch of regional freeway that have no obvious cause. The traffic speeds up after them. I doubt it would improve travel times much, and in the hands of bureacrats would just be an excuse to slow traffic when it is not needed.

There's certainly merit to the idea in crowded city roads - you can even get some of the effect yourself by leaving a large gap in front of your car to "smooth out" stop start traffic.

It won't solve everything though - a lot of traffic jams are caused by idiotic road design. Leaving a 40m gap won't fix that.

If you are doing that in the city you are causing traffic jams, not preventing them. You cannot smooth out traffic lights. All you will do is reduce the number of vehicles getting through on a green.

I'm talking about longer stretches of open road, not traffic lights.

Of course - the "plonk a set of traffic lights every 300m" phenomenon is another stupid piece of Australian road design that simply buggers up traffic.

None of the above.

Collectively People are stupid and don't understand that giving way and applying game theory to driving benifits everyone.

The only answer for increasingly congested roads is going to be automation,  and to start with adaptive cruise control should be compulsory. If you can't afford a car with automation,  catch a bus

Country/Rural people can drive, but they can't park properly.
City people can't drive, but they can park on a dime.
It's obvious, which one of the two is more important.
But Sydney & Melbourne are the false prophets of Australian culture for starters. One is Chinese, the other thinks its in China.

Of course - these two cities keep trying to squeeze more people in - for money. They can't say "We're full. Sorry." They don't know when to stop and hence why Melbourne is an accident and Sydney was designed to keep people employed fixing it all the time.

Things will only get worse in those two cities, never better. Their glory days are long gone since the year 2000 clicked over and they 'sold their souls' for the fast money, via a slow traffic crawl. Tongue

Sometimes I see people do this at a bottleneck on the freeway. It slows down the traffic. They don't catch up the next time the traffic stops. They just get further and further behind the car in front, with a queue of drivers banked up behind them.

The Japanese Professors said "Ants don't have traffic jams".

He needs to look at more than orderly little Japanese ants  Grin

Go to Africa & see how African Driver Ants go ....

if this isn't a traffic jam then what is it?

Oh, yes... I can just see motorists leaving a 40 meter gap between themselves and the car in front. Never going to happen.

Here in Perth all you have to do is leave a gap of slightly more than a car length between yourself and the car in front and someone will cut in front of you - regardless of the speed limit. Even at 100km/h on the freeways.

This is probably one of the reasons why there's so much tailgating these days.
