AVERAGE speed cameras are expected to be finally introduced on the A14 in Cambridgeshire in the new year. Following a week in which two multi-vehicle accidents caused serious delays for motorists on the A14, the Highways Agency has confirmed the cameras will be installed between Spittals and Girton. According to road safety figures, safety cameras have already played a major role in reducing accident rates on the A14. It is hoped the addition of the new technology, which uses cameras to measure a vehicle's average speed over set distances, will continue to reduce the number of incidents and cut back on tailgating - the major cause of accidents on the A14, according to police. The accident rate on the county's stretch of the road, between Hinchingbrooke and Girton, has fallen by 37 per cent since safety cameras were installed in 2003. A spokesman for Cambridgeshire County Council said the annual rate of deaths and serious accidents had fallen from 18 to 11. Figures for all incidents between 2002 and 2004 show an annual average of 200 personal injury accidents on that section of the A14. A spokesman for the Highways Agency, which this month joined police in patrolling the A14, said the problem was the road's dual role.
