On the same day that Department for Transport announced an increase in road deaths, Safe Speed has launched a 10 Downing Street petition to scrap speed cameras in the interests of road safety.

Safe Speed has a cast iron case against speed cameras:

* The benefit claimed for speed cameras has been overrated by 400% due to neglect of regression to the mean effect at speed camera sites.

* The claimed speed / accident relationship based on average speeds is basically complete drivel.

* Only 5% of injury crashes involve ANY 'speeding' vehicle - and that INCLUDES crashes caused by rogue drivers, nutters racing on the highway, reckless drivers, stolen cars, emergency services drivers and drunk drivers.

* Speed cameras come with at least 30 detrimental side effects, none of which have been officially studied.

* Vehicle activated signs are more effective than speed cameras at reducing vehicle speeds in dangerous locations.

* We earned ourselves the safest roads in the world long before we had speed cameras, but since we've had speed cameras we have been losing our world lead.

* Road deaths are not falling as expected.

* Road crash hospitalisations haven't fallen for a decade according to the British Medical Journal.

* If it wasn't for a sustained and ongoing reduction in pedestrian activity the road safety results would be considerably worse.

* The Statistics Commission has warned Department for Transport that their 'serious injury' statistics are not a reliable series - and that's the only category showing an improvement.

Paul Smith, founder of the Safe Speed road safety campaign(www.safespeed.org.uk) said: "I urge everyone to sign this petition for one reason and for one reason only - because speed cameras are detrimental to road safety."

"A proper examination of the case leaves absolutely no doubt that speed cameras have made road safety worse."
