Speed cameras that use GPS and number plate recognition have undergone testing in two sites in England. The SpeedSpike system captures the above information and then calculates an average speed over a distance.

The two sites where testing was undertaken were Southwark in south London and the A374 in Cornwall.

News of the testing came to light in evidence to the House of Commons Transport select committee by system designers PIPS Technology, the same company that designed the technology used for the London Congestion Charge Zone.

I believe the new speed cameras that have started being purchased (in NZ) at the end of last year are also capable of this ...

Can't see the point, except on motorway where everyone is already travelling at 110k. Bikes can maintain a very high average-to-maximum speed ratio as the opportunities to pass are readily taken advantage of, and it's not against the law to hold a constant 98km/hr.

What it does, is to take your position and time (plus speed being travelled) at point A, then the next camera takes your position and time (and speed being travelled) at point B. Then it works out the average speed, based on the time taken at each point.

So, if you were recorded as going faster than the legal limit at either camera, you get done. If the time it took you to get from point A to point B means you had to go faster than the legal limit, you get done. Double-edged sword, see?

My father-in-law has a couple of average speed cameras where he lives. So, if he thinks he sped up, he finds somewhere to pull over for about 30 seconds, as it will drag his average back down!

Shite, really? I commute through there daily. Myself and many others hoof it through there. There's three normal speed cameras on the way into central London, but they're all very visible and easy to spot.

This has been up before. I reckon apart from motorways our speed fluctuates to much for the cameras to be more effective than normal ones. Their is no way I can sit at 100k on any road round here, even SH 1, too much traffic travelling at 80kmh. By the time I have followed waiting for a safe overtaking opportunity exceeding the speed limit to get past would be irrelevant. Could be a pain for those who habitually sit on the wrong side of the law though

Just did a bit more checking - the site was Salter Road. Hope this helps.

You think we have it tough!? The bloody Ozzie cops now have speed cameras hidden in cats-eyes!!!! They have hem set to take rear photos so bikes get tagged as well. And you'd think the Ozzie gov get enough revenue from selling uranium. Bastards!
