Safe Speed Forums

The SCPs are fond of citing reductions in accidents at camera sites. Does anybody know what constitutes a "camera site" for this purpose? How far from the actual installation does the site extend?

The reason for asking is that there has been a fatal accident locally a few hundred yards from a camera and I am interested to see if this will be ignored in published statistics.

Section 3.6 of the DfT Handbook of Rules and Guidance for the National Safety Camera Programme for England and Wales (2005/06 and 2006/07)states:

3.6 SITE LENGTHS
A site length is the distance between two points within which collisions, casualties and speeds are measured and camera enforcement takes place. Generally, once the site length has been approved by the national safety camera programme board it should not be changed since this acts as a baseline for ongoing measurement of casualty reduction at the site. Where the site length must be changed for operational reasons, care must be taken to ensure that the distance over which collisions are measured before and after establishment of the site are consistent.
Sites lengths should meet the following rules. However, the lengths of sites approved prior to April 2004 may fall outside these limits.

Type of site / Site length rules
Fixed speed camera Sites / Between 0.4 and 1.5 km
Mobile speed camera sites / Between 0.4 and 5 km

Sites using time over distance equipment may extend beyond this length. Enforcement along a number of longer routes containing a number of core sites has been approved under provisions in previous years’ Handbooks. Approved routes may continue to be operated, subject to the review of all existing sites set out in Chapter 5. The provisions for route enforcement are being reviewed during 2005/06. Further routes will not be considered while this review is carried out.

It depends. If they are using the stats to justify a camera then the area is bigger. Once it has gone in the area shrinks to make the accident reductions look bigger

I'd imagine the death near to a camera will be glossed over if possible.
