Alan Buckingham, a sociology lecturer at Bath Spa University College, claims his research shows no link between safety and speed cameras, contradicting the beliefs of road safety groups.
Buckingham said: 'Speed cameras are not saving lives. We have all become accustomed to the message that 'speed kills', but my research shows that there is no simple relationship between speed and death.
'Speeding is rarely the primary cause of fatal road accidents, and attempts to catch speeders through increased use of speed cameras are failing to make our roads safer.'
Buckingham's research looks at trends in road fatalities from the early 1990s, compared with those since the introduction of speed cameras. He said the number of fatalities failed to decrease following the introduction of the cameras.
However, road safety organisation Brake says the cameras are vital to reduce speeding and to cut accidents (Fleet NewsNet October 28).
