Table 5: Average speeds at safety camera sites

The most recently recorded average speeds at mobile camera sites are lower than the baselines recorded for all speed limits. At fixed camera sites current average speeds are below or equal to baseline levels at all sites. In most cases, current average speeds at fixed and mobile camera sites are below the posted speed limit; the exception is 30-mph mobile camera sites.

Table 6: Percentage above the speed limit at camera sites

For mobile camera sites there has been a reduction in the percentage of vehicles recorded as travelling above the speed limit for all speed categories, while for fixed camera sites there has been a reduction at 30- and 70-mph sites, and an increase at 40-, 50- and 60-mph sites.

Just over half of all fixed camera sites are sited on 30-mph roads. The relatively low numbers on roads with other speed limits means that comparison of findings for different speed limits are unlikely to yield significant results. Similarly, comparison between fixed and mobile sites is not appropriate for anything other than 30-mph sites. However, at 30-mph sites there are greater reductions in the average speed and percentage above the speed limit at fixed camera sites.
