My parents have come over from Switzerland and I have insured my dad to drive my car for 2 weeks. Anyway he's been driving it fine for the past week, but tonight on the way to Sainsbury's ( Archer Road) he went through the speed camera on ecclesall road south! He was on the Henry Boot side. My question is does the speed camera work only on the other side?

He apparently said he was doing 35... It's such a shame because we really are scared now, and they've come over for a holiday, not to worry about this!

According to this site (http://www.rocknroll.force9.co.uk/advice/gatso.html), the speed camera operates on the North-East bound way.

I would think it only covers this way but I can't be sure *covers back for legal reasons ;)*

Hope this helps :) And I hope your parents enjoy the rest of their time here

That camera is for traffic passing into town only.

100% sure??

Yep. The way those camera's work is to take two photos immediately after each other. Don't know the full technical detail but the sensor for it is as you pass the camera, I believe. There was a link to a website on another thread (dont try searching for speed camera though you will get about 2000 options to chose from!) which explained it all.

aaaaaaaaahhhhhh! thanks for that. Really has put my mind at rest!

Still can't undertand how a camera can only work on one side of the road? Tried to search the forum, but 1000's of posts on speed cameras!

Traffic going away from camera:
1st "ping" is quicker to return than the 2nd ping, so the calculation of speed involves a subtraction of "Measurement #1 from Measurement #2"

Traffic coming towards camera:
1st "ping" is slower to return than the 2nd ping, so the calculation of speed involves a subtraction of "Measurement #2 from Measurement #1"

If you can see that the programming for the calculation is different, you can see that a camera can only be programmed for vehicles coming/going from/to a given direction.

(hope that makes sense)

My old automotive engineering teacher always used to go through that camera at 36mph; he'd done 'tests' on it and found that it wouldn't trigger below 37!


Regarding the one-side-of-the-road-only thing, aside from the programming issue, the camera has to be pointed directly along the section of road it is monitoring, in order to be able to differentiate between traffic in different lanes.

According to his speedo ;)

Our MkIII Astra used to read 100 when Mr Strix's company MkIV was reading 90 :suspect:

I wouldn't rely on that, programmers are actually smart enough to realise that a -'ve would be a car travelling the other way and invert the equation.

Fortunately the actual physics of the cameras (ie they have to be pointed at a lane as previously said) means that they only work 1 way. But don't always assume that it's as you pass it, some cameras work the other way and photograph you approaching it (tuvelo work that way), specs work the older way.

if the camera flashes you in the face it is programmed to catch cars in the opposite direction i.e photo's them after going through the light not approaching.Gatso's aren't allowed to "flash" u face on for safety reasons.
only tulevo - red lenses can get u both ways, just observed the angle of the camera. an acute angle indicates it is getting you from behind (behave).
an obtuse angle indicates it is filming the opposite carraigeway & will get u head on.

Not something to try but what happens if you reverse past a speed camera breaking the speed limit?

Dragon

and what type of camera is on ecclesall rd south?

What' he worried about? he'll be back home before the ticket comes through!!!

If he hadn't been speeding in the first place, then this wouldn't have been anything to worry about. WOULD IT?

so you just declare who was driving.

You weren't driving it though. Were you?....Last time I got caught by the speed camera you could quite clearly see me in the driving seat (and my little lad sat at in the passenger seat picking his boogers!!!!) You cannot be prosecuted if you were not driving at teh time. You have insurance / cover note to show you have put your father on the insurance for this period aswell I would assume?

You will be asked on the ticket to give your father's name and address.
It would be interesting to see if they follow it up with European citizens.

I certainly have! Just wouldn't like to blame my dad really!! Not exactly a warm welcome from me sending him a speeding ticket lol! I wouldn't have thought they'll start chasing him in Switzerland?
I do know he's an excellent driver but what went wrong was the fact that he doesn't of course know Sheffield's roads, didn't know which lanes to get into etc+ he works in kms.
