No news on GDE speed limit front

By 13 December 2011 94

I’ve written up another article re the GDE speed limit, with a table comparing road characteristics of the GDE, with others around the territory. Read on if interested:

I have not heard much on the GDE speed limit front. Last time I drove the road, the speed limit continued to be 80 km/h. Travelling at 80 km/h without cruise control is difficult without slipping over every now and then, after all, the brand new road was designed to cater for a speed limit of 90 km/h, thus the road encourages high speed.

Point to Point speed cameras are still on the way too. The situation is arguably absurd, the majority of people I speak to about the issue seem to agree.

To highlight the inconsistency of the 80 km/h speed limit of the GDE compared to other roads in the A.C.T, I have put together a table for you.

Have a look, and decide for yourself if this particular combination of near freeway quality road, an 80 km/h speed limit, and impending point to point cameras, is about safety or revenue?

Image: The Gungahlin Drive Extensions speed limit of 80 km/h is incredibly inconsistent when compared to other roads in the A.C.T, and yet the road has had point to point speed cameras planned even prior to it opening. Click the table to enlarge it.

The f**kers in the fixed speed vans were parked halfway down the hill after the Aranda turn off today.

No, I’ve never been booked by them, but its a pathetic revenue raising effort without any hint of road safety thrown in.
F**kers.

It’s really not that hard to do 80km/hr on the GDE. Just ignore everyone who thinks the speedlimit should be 90 or 100. Bring on the enforcement, I reckon.

Totally reasonable!

Design a near freeway quality road with a 90 km/h speed limit in mind. Open that road with an 80 km/h speed limit, one of the lowest in the developed world for such a road (despite identical and even higher speed limits on lower quality roads in the same jurisdiction).

Enforce said speed limit with as many speed cameras as possible.

Quash questions from protesters with labels of “hoons” and arguments of “if you cant obey speed limit don’t drive”.

Profit.

Roads wrongly-signposted like this are the precise reason why most Canberrans treat the posted limits with the contempt they deserve.

Virtually nobody pays any attention to speed limits these days and drives at 5-15Km/h above the limit.

The idiots who really bug me are the ones who insist on travelling at 70Km/h in these 80Km/h zones, thinking they are sticking to the speed limit.

Were the cameras fixed to the vans?

I think it is pretty clear to all that the cameras are there to punish people who cannot stick to a arbitrarily assigned (as the good sarge shows) numerical rounded number (why are speed limits not more exact? 37km/h on some roads, 86km on others).

Personally, I haven’t been caught in a couple of years* so count myself pretty lucky. (* – never by a camera though….).

Yeh I saw the F#ckers, parked behind the trees on the downhill bit obscured by the slight bend in the road.

F#cking, F#ckers, the road safety arguement is in tatters.

I’m all for obeying the law. I’m also for the law being sensible and reasonable. I see no adequate reason why the GDE speed limit is 80km/h. Point to point speed cameras on a brand new stretch of road with an unnecessarily and unreasonably low speed limit are clearly about money making, and nothing to do with safety.

Nah, it’s a lot more than 500m that’s not duel – truly duel, anyway. From the roundabout at Drake Brockman, down to the overtaking lane near Coppins Crossing, the citybound lane is single lane.

And to be honest, it’d probably be better if that section of overtaking lane was switched around so it wasn’t even there for citybound traffic, it causes holdups through idiots deciding to overtake and then failing at merging once it ends, I’m sure it’d be faster if the other lane was given back to the Belco bound lane, so it was actually duel lane all the way.

You Sir, are a clown. The speed limit is just that: a limit. Not a minimum, not an average, but an upper limit above which you’re (probably and arguably) driving in an unsafe manner. I pay attention to the speed limits, generally flicking the cruise control on 2-5km/h under the limit. As such I get abused, flipped off, tailgated, et al. I then arrive at my destination 2min after said lunatics. I have a job with enough inherent risk and danger that I can justify. What I couldn’t justify is injuring myself or someone else on the way home to my wife through arrogant stupidity.

Wouldn’t a duel carriageway be a single lane with “One Way” signs pointing in both directions?

F**kers.

Oh the van has been sitting regularly on the downhill section of the road since it opened.
But I suppose its worth it because I’m yet to see an accident on this stretch which obviously means the continued speed enforcement is working. Right?

In the table you mention for the GDE : on road cycle lane (yes) and segregated cycle lane or path (yes) . A segregated cycle lane or path would have a physical means of separation, ie barrier or median, so on the GDE it is only ‘on road cycle lanes’,for the majority of its length.

But I would agree the speed limit should be higher but there should also be physical separation of the cycle infrastructure as well.

Thankyou Sarge for taking the time to lobby the issue rather than the majority of the population that scream out f**kers in no particular direction and do whatever speed they feel like, and abuse those who stick to the legal limit left lane or right.

2-5km/hr under the speed limit? Would love to know why you do that.

I’ve used GPS to calculate the accuracy of my speedo: -7km/h was the result.

So even driving with the needle on the speed limit, I’m already doing 7 under. In most cars, a difference of over 5km/h is typical. So when you drive at 5 under according to the speedo, you’re easily doing 10-12km/hr slower.

Kind of demonstrates an often overlooked lesson in road safety: know your vehicle.

I don’t mind if some people decide to sit 10km’s under the limit (in the left lane mind you), however I hate it when there are 2 people sitting side by side on the GDE doing 70km or less each, I don’t care about the person in the left lane as they can do whatever speed they like, tho for the person hogging the right hand side sitting at 70km either speed up to the limit and go into the left lane or slow down and go behind the other car already in the left lane so then the half of Canberra waiting can go on their merry way. The extension was supposed to speed things up.

Also I would like to point out to those who seem to think they can pull out in front of cars doing 80km making other cars slow down very rapidly to 30km-40km or so then sitting on like 70-75km’s you people are the biggest A$$es (most I find pulling out of Forde). Why cant you wait for that one, two or maybe three cars to go past. If i ever do hit one of you people expect to go bankrupt after court… ;)

Also people remember a merge lane works a lot like a zipper…..

So is your “Correct Speed Limits for Our Roads” Party going to be registered in time for the 2012 ACT Election? Are you going to widen your appeal and have the “Correct Speed Limits, better deal for cyclists as long as it doesn’t impede motorists, won’t somebody think of the children, crush the cars of multiple drink driving offences Party”…

Given it’s a speed LIMIT, how much under it am I allowed to drive before I annoy you? Just so I know. Would 72 be okay? or still going too slow? do I have to sit at 78-79 for your happiness and so that I don’t ping any of the fixed, mobile or vigilante speed cameras set at 81+!

Remember it’s not a Speed Recommendation or Speed Requirement. It’s a speed limit.

Sure if someone is going 45km/hr in an 80 zone in a bunged up piece of junk then you are going to be held up…..briefly… there are plenty of opportunities to overtake, re-route etc to get to where you so urgently need to be (we must have a lot of Doctors delivering babies in Canberra with all this required speeding).

In other parts of the world, those who know their car doesn’t make the grade (speed wise) will generally shift into the hard shoulder and let you get past.

If you keep left unless overtaking, it really won’t matter if some people drive below the speed limit. Sheesh!

What about the noise for aranda folks, and also the argument that the speed limit changes a few times around there so best to keep it consistent 80?

I figure if you don’t have the skills to drive at the speed limit then you probably shouldn’t have a license.

If you feel the need to drive at 10kmh under the limit for no reason – then you probably aren’t very good at driving. Perhaps you could take some driving lessons or something?

To add salt to the wound, try adding Pialligo Ave to the above matrix. Scary. Just where is the logic in ACT Roads?

So they are going to go bankrupt after you run into the back of them? I believe that if you hit them after they have pulled out and you have failed to slow down, you might be the one with some legal issues. Yes, they may be stupid for pulling out, but you still have a requirement to take measures to avoid an accident and slow down for traffic in front of you, leaving a safe distance.

I watched some tool on Hindmarsh Drive this morning who was having trouble understanding what a safe distance was. He found in a hurry when the van in front of him hit the brakes hard to avoid hitting the car in front (no idea why they were braking, just saw the concertina effect) and ploughed into the back of the van. The tailgaters car looked like it had hit a brick wall. The van had a small ding on the rear door and some scratches on the tow bar and rear protection bar.

By my calculation, the difference between doing the entire 9km GDE at 80km/h and 90km/h is just 45 seconds. Even less when you include start-up times and traffic delays. To put it another way, the difference is much less time than it took OP to create the table.

The increase is speed increases noise for nearby residents (who were promised an 80km/h limit), decreases fuel efficiency, and is significantly more dangerous to more vulnerable road users (namely cyclists and wildlife).

Simply set your alarm clock 45 seconds earlier and get on with your life.

The GPS is not an accurate speed measuring device. It’s accurate to about 10m on a good day, so any measurement of speed is based on measurements of location that are up to 10m out of whack. At 90km/h you are doing about 30m/s, which means your GPS could actually be up to 1/3 incorrect.

A better way to calibrate your speedo is to find one of the 5km marked sections of road (Northbound on Tuggeranong Parkway, from the top of Oakey Hill down to the Cotter Road overpass is one such stretch) and time how long it takes you to travel the 5km when doing a consistent speed.

Travelling 5km at 100km/h should take 180 seconds on the dot. To calibrate, hold a steady speed and start timing when you cross the start line. At the stop line, record your time T in seconds. Your actual speed is S km/h = 5km / Ts x 3600s. Thus if you complete the trip in 170s, your actual speed is 106km/h (which fails the legal standards of reading the speed or within 10% below the actual speed). If you complete the 5km in 190s, your actual speed is 95km/h which explains the tailgaters and bird-flippers.

Of course, you can use your GPS to time the trip, since GPS relies on accurate timekeeping.
