All safety camera sites are selected with
the aim of reducing speed-related crashes and casualties.
Each site is selected using strict criteria
from Department for Transport, which looks at the number of
speed-related crashes and casualties over the last three years.
This criteria is there to ensure that cameras will only be placed
at locations where they will have a positive effect on speed-related
crashes and casualties.
The first step of the selection process is
for the Highway Unit of the relevant District Council to ascertain
the number of speed-related crashes and casualties at the proposed
location. This is done using a crash and casualty database that
is maintained using police records of crashes and casualties.
This system allows analysis of all the crashes and casualties
along a chosen route.
The second step of the process, unless the
site is for a proposed red light camera, is for the Highway
Unit to conduct a speed survey using speed data collection equipment.
This equipment is deployed for 5 days at a time and records
information on every vehicle that passes over it, including:
- Speed
- Weather
- Temperature
- Time of day
- Traffic flow
- Vehicle size
This data is then downloaded onto a computer
for analysis and the information will be used to ascertain if
there is an actual speeding problem.
The third and final step of the process
is to have the site surveyed by a qualified road safety engineer
to ensure the site is suitable for safety camera enforcement
and there are no other viable engineering/road safety measures
to rectify the problem.
Once all this information has been collected
and analysed, the type of safety camera enforcement, if any,
can then be decided upon and a formal request for a safety camera
site sent to the Department for Transport for approval.
