To ask the Secretary of State for Transport what the average reduction was in the number of people killed or seriously injured in the 12 months after average speed cameras were sited on the A14 between Girton and Fen Ditton; and whether he has calculated any nominal monetary value which could be attributed to any such reductions.

In the 12 months before the safety camera scheme was installed, there were one fatal, one serious and nine slight personal injury collisions confirmed on the A14 between Girton and Fen Ditton. For the 12 months following completion of the scheme, there have been one serious and four slight personal injury collisions confirmed.
The benefits of a scheme are normally evaluated over a three-year period and it is too early to state that the reductions in the number of accidents on this section of the A14 have been wholly due to the safety camera scheme. However, using the Department for Transport's Transport Analysis Guidance on appraising transport interventions, the reduction in casualties currently represent an estimated nominal monetary value of £1.99 million saved.
