Table 5: Average speeds at safety camera sites

Mobile Fixed
Speed Limit Sites Baseline[8] Current Sites Baseline Current
30 mph 76 33 mph 31 mph 87 31 mph 26 mph
40 mph 8 44 mph 39 mph 11 35 mph 35 mph
50 mph 7 51 mph 46 mph 3 47 mph 47 mph
60 mph 77 56 mph 54 mph 39 53 mph 53 mph
70 mph 19 69 mph 65 mph 19 67 mph 63 mph

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

Mobile Fixed
Speed limit Baseline Current Baseline Current
30 mph 63% 49% 45% 14%
40 mph 64% 27% 18% 22%
50 mph 58% 36% 25% 27%
60 mph 30% 22% 12% 17%
70 mph 58% 23% 33% 26%

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.
