The Scottish data can be found in the Statistical Bulletin, here:
http://www.scotland.gov.uk/Topics/Stati ... ce/SafeCamI have, of course, complained to Rob Wishart (see page 20) about the statement that:
"The number of people killed or seriously injured at safety camera sites is 63 per cent lower after camera enforcement."
... on the grounds that it suggests that the effect of camera enforcement is to reduce KSI casualties by 63% (to the best of my knowledge, the only credible assessment of its effect remains Appendix H of the 2004 Evaluation Report - 19%).
I have suggested that time series and camera effect should be clearly separated in an "Official Statistics Publication".
I await Mr Wishart's reply.
