I requested these figures from the 'Avon, Somerset and Gloucestershire Safety Camera Partnership' for the total amount of detected speeding offences for 03/04, from Fixed Gatsos and mobile van units in their entire area covered.

They have 98 fixed camera sites (gatsos) and 9 scamera vans operating at 233 locations.

Before I give the figures, take a reasoned guess at what detects the most offences - fixed or mobile?

Also, assuming the mobile vans were operating 12 hours a day, 7 days a week, how many speeders do you reckon they catch per hour per van?

Hope this isn't too boring, it's just I dont believe the figures these partnerships quote, but HOW could they be legitimately disguising them?

So c'mon, have a guess - how many speeders does the average scamera van catch per hour?...

In a 30 zone I would guess at 150 per hour?

No clue though, depends on the road, time of day, location of scamera etc etc

I can't answer your queries on how many per hour as there is no upto date data saying how many prosecutions there are per year. The last figures I read about in the local press were for 2002 when there were 10,000+ prosecutions per month being issued in the area, of which about 5% were from road traffic police.

I would expect this ratio to be maintained so that I'd guess 95%+ of prosecutions in Avon & Somerset are based on scamership issued NIPs. I would guess that about 85% of scameraship prosecutions are mobile and 15% static yellow box gatsos.

I'd also guess they have improved their revenue stream by uping the prosecutions in the area to about 13,000 per month.

No idea on figures, but I'm guessing the Talivans catch more than the fixed Gatsos.

I would be SERIOUSLY impressed if you managed to get data out of A&S scammers. I asked them for figures last Feb for accidents at a certain camera site - still not got a meaningful answer, and I've been fobbed off every which way, told to talk to all sorts of people, all of whom have referred me back to the scammers. Grrr

I'd guess the vans catch more than the fixed cameras.

If they have 98 fixed sites, that probably means they've got, what, 20 or so actual cameras that they move around between them ?

Given that the cameras are very visible, but the vans are often somewhat hidden, I'm sure they'd catch more people than the gatsos.

I reckon the vans catch way more than the fixed sites.
On certain sites that I used to park at the mobile camera would run out of film in two hours, thats approximately 200 offenders...and I wasn`t hidden!!!
Still I`ve finished with all that tat now.

The figures for each camera are now on the website.

Where does the 98 for fixed sites come from ?

They are now point blank refusing to answer "How many accidents are speed related ?"

KSI figure for 84 Gatso's are

1999 36
2000 35
2001 32
2002 42
2003 36

On a tape (unknown length) from a talivan 217 vehicles were zapped by the expert and 36 were over the threshold speed

Doesn't supprise me as you round the bend, see the van but by then he's already zapped you It's not the hinding that's the problem, it's that they are forward facing and long range, thus you can't slow down for them!

What about 2002 and where are 2004 figures? It can't be that difficult to compile figures for last year.

If there are no figures for 2002, you can bet deaths went up. Should be able to use the freedom of information act to find out

Headline: "Dramatic KSI reduction in 2003"

Text: "Scamera Partnership members are congratulating themselves on the huge 24% reduction in KSIs between 2002 and 2003. This is clearly due to the Partnership's active and visible presence. The local population are all fully in support of the planned rollout of additional cameras and vans because they clearly work."

Editorial (some hope!): "But even now the figures are only down to 1999 levels when there were no cameras and vans. When is the Partnership going to come clean over what's really happened on our roads during the past 5 years?"

Interesting guys, your views are the same as mine , I thought camera vans would be detecting far more offences than gatsos, infact Im sure they do but cant prove it!
Heres the figures from the newly appointed freedom of information manager, copied and pasted :


FOI Request re: Detected Speeding Offences

Thank you for your correspondence dated 8 January 2005.
Please find below the information you requested.

The total number of detected speeding offences for the Partnership's operational year 2003/04
(01/04/03-31/03/04) over the total area covered (Avon, Somerset and Gloucestershire) from:

1. Fixed Cameras = 79,272

2. Mobile Cameras = 52,573


Now , do you believe that?!!

Assuming the 9 mobile vans operate 365 days a year for 10 hours a day (not 12), then, and please check my calculations, this equates to each scamera van detecting 1.6 speeding offences per hour. (yes one point six)!

Now tell me they're not on the fiddle!

Cuneus, the 98 for fixed cameras is stated on their website under 'facts and figures' on the left menu.

That very nearly £8 million in fines = nice little profit for the treasury
