bagheera: ...even if can not have 2 setting for speed, all you need to do is take ALL photo of car going over 60, and throw any photo in lane 1 - x that is 80km/h limit if it below 80, and keep if over, not hard to program, and even if not in software, it easy to do with 1 person reviewing the photos.

When the speed limit is 80 in one direction, you're going to be taking a photo of basically every car going in that direction. That would be hundreds of cars an hour. Maybe thousands during peak.

You'd have to have a team of people working full time around the clock just to keep up.

as i say, it not hard to program something that goes lane x throw away if speed is x -> y

There are video examples of traffic cameras simultaneously tracking multiple vehicles across several lanes so that's believable. What I'd like to know is how does it see the number plate when there's a median barrier in the way? The camera doesn't have that much height where it's mounted.

Just use cruise control. My car just goes at the speed you set.
All you have to do is push the button to drop out if the car in front gets too close.

No brakes or worrying about going to fast.

Afaik most car manufacturers strongly recommend against using cruise control when going up or down hills, and they probably mean that in relation to much flatter hills than the 'gorge

Bah... I was driving a Ford Mondeo with Cruise Control and distance control so didn't even have to push the button to cancel it, the car did everything.

But seriously, not every car has cruise control. I'm glad you put that emoticon there.

Absolutely nothing in the manual re that. In fact it is encouraged to use it.

Maybe that is for "older" systems. This one changes the gears including down a gear or two to hold the speed going downhill. Also handles dropping across to the "manual mode" and manually changing gears if you want to "play". No idea why you want to but its fun when bored on a long trip :)

I also find the fuel economy is way better in cruise compared to me trying to do it.

Would love to try distance control on some of the roads here.
Coming up on logging trucks going up the hills on the Taupo Napier road for example.

Hey got to have some toys and fun when out doing the miles.

So whats the point of remotely changing the speed limit if someone has to review and interpret the photo, just saying

Methinks a whole slew of drivers who've been heading uphill are going to be getting unexpected tickets.

If anyone here gets one, please request a copy of the photo and post it up. Would be interesting to see what the viewing angle is and if licence plates of cars close to the median barrier can be seen. I'm guessing they can as the camera's uphill focus point would be quite a way down the road.

Which leads to a question: has the downhill focus point been changed? If it has, the common practice of slowing down for the road sensors then speeding up again will have also generated a load more photo's.

Someone here will know someone in-the-know and can maybe glean some knowledge they can post.

Another guess from me is that the camera will frame the offending vehicle. OCR will take care of the registration plate and a computer program will generate a ticket to be posted to the registered owner along with a computer generated letter of explanation. Not much human interaction required at all apart from some sort of validation before the ticket/letter gets posted.

I have not read anything re the new "cameras" in NZ but based on other info in the news here and overseas I suspect
1 every car going past will have an image taken
2 every number plate will be analysed and stored in database with time stamp and speed stamp against it
3 plates will be checked against "stolen" register. No doubt later against current rego and WOF and some more automatic revenue increases.
4 the lasers will just provide data over the image to keep the courts happy that speed was logged at the same time as image taken.
5 anyone doing more than the "tolerance" will get a fine to keep the revenue flowing. Then when you park in Wellington there will be another revenue income as well.

I am not into conspiracy or other but that is current technology and plate recognition is already being used. Just get used to it!! It you are not breaking the speed limit you have nothing to worry about!! But of course we also now can check out alibis for anything else relating to any vehicle.

Boy I am glad I live in the country and only visit the cities to see the clients

Some judge in OH decided that too much is too much and calls speed cameras a scam...

Well if you have an auto transmission then thats a different story but its discouraged with manual transmissions for the above reasons. There's still plenty of general advice on the net discouraging cruise control use on anything but flat roads

The changing down gears will be more to do with the transmission than the cruise control, in the same way that if you were to hit a hill but keep the same pressure on the accelerator as on the flat, then the gearbox will downshift for you

They haven't mentioned this being one of the ANR (Auto Number Recognition) cameras. They were trialling some around the country though.
Although busy choke-points like the Gorge would be ideal places to have one (from their POV, not mine...).

Shouldn't be necessary - cars going towards the camera have a positive speed, cars going away from the camera have a negative speed. How hard is it to say "photo if over +80 or if under -60" and then alter either of those numbers to suit.
