SID stands for Speed
Indicator Display. SID is a mobile vehicular actuated sign,
which reminds and raises motorist’s awareness of their speed and
encourages them to drive within the speed limit.
SID
is an interactive variable message sign that is portable, capable
of measuring and recording vehicle speeds. It displays the
motorist’s speed, with a view to encouraging them to drive within
the speed limit. SID is essentially the friendly side of speed
enforcement, non-threatening but never the less effective. Speeds
have shown to be reduced during SID’s visits and early monitoring
of accidents, shows pleasing result.
SID works by embarrassing motorists into complying with speed
limits, by displaying their speed for all to see. If drivers are
within the limit their speed is displayed followed by a smiling
face, as if to say thank you. If the speed displayed is above the
speed limit, then SID produces a disapproving frown.
SID is deployed anywhere in the county where there may be a
perceived speeding problem within a 20, 30 or 40mph speed limit.
SID will be deployed at requested location (as long as it is safe
to do so) for a hour at a time. Each requested location will
receive 3 visits and speeds will be recorded and downloaded.
Once 3 visits have been undertaken, each site is ranked against
all others visited throughout Suffolk, to determine their re-visit
criteria. The data collected by SID is available by clicking
on the link here. If the data recorded at a location is found
to be above the Police’s enforcement level, this information is
passed to the police.
The deployment of SID is via SID cars, these are specially
liveried Smart Cars resplendent in yellow and black paint work. The
object is high visibility but friendly persuasion speed
compliance.
