Derby speed camera cover-up prompts 440% speeding increase
A trial which saw four speed cameras in Derby covered up for five weeks resulted in an increase in speeding, according to the city council.
The average number of drivers breaking the 30mph limit in one area - Osmaston Park Road - went up by 440% each day.
Tim Clegg, director of the council's Streetpride service, said the cameras had reduced the "number and severity of road traffic collisions".
Councillors are being urged to retain three of the cameras.
The cameras were temporarily switched off in summer 2011.
At Harvey Road, the number of drivers exceeding the speed limit during the trial rose by 400% compared with the previous two weeks, according to the authority.
On Nottingham Road in Chaddesden, the figure was 166%, and on Derby Road in Spondon it was 157%.
Mr Clegg's department is recommending that the Nottingham Road camera is permanently removed because there was no reduction in accidents since the camera was installed in 2003.
Councillor Hardyal Dhindsa, Labour's spokesman for planning and the environment in Derby, said the cameras should be maintained.
He said: "We feel speed cameras do have a value and the evidence from this report demonstrates that."
Councillor Matthew Holmes, Conservative cabinet member for planning and the environment at the Tory-Lib Dem council, said complete removal would sometimes be the right option.
He said: "I still fundamentally believe that the public support us moving on from fixed speed cameras."
He and a fellow cabinet member said they would consider the recommendations at a meeting next week.
