tris- said:in the end why does it matter why they are there? dont speed, dont pay a fine. regardless if you think your schumacher or what ever. or if you get caught, say its fair play and your own fault.
not you personally ofc, in general.
Golena said:Simply put they are a crap system.
People simply drive at 50 until they see the camera then slam the brakes on drive through at 25 then straight back up to 50 again. Camera's outside schools would make some kind of sense to ensure people slowed down where there's likely to be children in the road, but since most of them are placed on roads where the chances of running over a pedestrian are actually fairly small then who cares.
It takes 2 days in an area before you know where every camera is.. They don't discorage people speeding in the slightest, they are simply there to tax money off people that stray 1 or 2 miles outside the limit accidentally. If you think that you need to be going 34 in a 30 zone to get flashed, your very wrong! They are actually more likely to get people traveling at the speed limit anyway, since they will tend not to slow down for them. The people speeding about at 40 will over break for camera's in general since they are actually paying attention to them and are therefore less likely to get flashed.

soze said:The fact you get points here should got to prove there not trying to milk your cash.
Yeah the cash gose towards processing the tickets and the rest wil now go back into the councils road safety fund. not the goverment.tris- said:if its just about punishment theyd ONLY give points. they do infact charge you money aswell.
its here nor there tbh though. the cameras are there, the reason doesnt matter
I always thoguh that was a old urdan legend and people though that because only some had the film changed every week so people assumed that it was the cameras being swapped with other machines.old.Tohtori said:You people do know that 3 out of 5, or somewhere round that ballpark, boxes are empty and have no cameras at all.

But i think now they are all digital there is not that problem.
But you never know
tris- said:would of thought speed cams use some kind of CCD or video recording.
soze said:I would love cameras that sat a mile away from each other hidden and take a pic at the start of the mile and at the end then it figures time between and charges you on the average speed. And just move them all the time so people can't get used to where they are
Yeah i think its being trialed.tris- said:i think there is a piece of road like this in or near doncaster that ive been round. except the cameras are static but im sure it measures the average speed
Bahumat said:The girl who says "if you hit me at 40 i'll die, but if you hit me at 30 there's a 80% chance i'll survive".
maybe im sick and twisted, but its like she's willing you to hit her at 30
soze said:Actually you have a problem with your car if your speedo is off like you have under inflated tyres or have changed the soze of your tyres. It is not normal for the speedo to be off.
But that is why speed camers trigger at 34 in a 30 zone 10% for the cars that have a problems
Darzil said:I used to work in a plant that made speedo's. They are essentially analogue devices, and aren't 100% accurate. Legally they can show up to 10% less than the actual car speed, but aren't allowed to show more. They tend therefore to aim for 95% of the actual car speed, with about a 3-4% variation from that.

tris- said:i take it your on board CPU is some kind of navigation system?
if so, how do you know its correct? are you factoring in the delays for transmission to and from the GPS satellite, your CPU abilility to convert distances over time into speed (with data that is transfered from a sat in space) etc?
the only way your CPU is 100% accurate is if there is some sensor on your wheel and and something attached in proximity (like your wheel arch) which measures your wheels RPM and converts it on the fly (with a very small margin of delay) into readable speed.
Darzil said:Wrong size tires can be a problem, a mate of mine got caught speeding, the bloke he'd bought the car off had fitted larger wheels, but hadn't got the speedo recalibrated, so he was doing more then the speedo said.
tris- said:do the speedos get calibrated individually or is the batch assumed to be correct from one test?
just interested in the process. the knowledge may come in handy in my future years
