A speed camera campaign which raked in more than £1m in fines for Thames Valley Police has had no effect on accident rates.

Last April, the force was one of eight in the country chosen to take part in the pilot scheme.

Extra resources were ploughed into catching more speeding motorists in the hope that it would reduce the number of serious injury and fatal accidents in the region.

More than 87,000 drivers have been caught on film speeding since Thames Valley launched the Safer Roads Campaign. The scheme has already netted more than £2.19m in fines.

Under the pilot rules, the force has been able to claim back £1.5m of this to re-invest in its speed camera network.

But, according to figures released this week by the Government, the campaign has failed to have any affect on the number of people killed or seriously injured on roads covered by the cameras in the Thames Valley.

The other seven forces in the trial all had much more success, showing significant drops in the number of people killed or seriously injured on their roads.

Thames Valley has always denied using the scheme to increase revenue -- claiming it was only aimed at making the force's roads safer. Officers have vowed to carry on targeting speeding motorists.
