SpeedVISOR is a vehicle activated sign that detects and records the speed of passing vehicles. The front of the unit has the words “Speed Check” beneath bright light emitting diodes (LED) to display the speed limit to motorists contravening the prescribed local limit.
The principal role of the unit is to raise awareness of speeding as anti-social behaviour. By displaying the speed limit to speeding motorists, the sign will draw attention to the speed at which they are travelling and remind them to moderate their speed to an appropriate level below the speed limit
The phase of operation at which the LED display of the SpeedVISOR Sign is disabled and the “Speed Check” text on the front of the unit covered-up. In this phase, the unit only monitors and records the speed of passing traffic.
The phase of operation at which the “Speed Check” text on the front of the SpeedVISOR unit is uncovered and the LED display activated. In this phase, the SpeedVISOR unit monitors and records the speed of passing traffic; any vehicles passing at speeds of greater than 10% in excess of the speed limit activate the display on the front of unit and the LED sign flashes the designated speed limit to the driver of the passing vehicle.
№ of Observations: The number of readings recorded by the radar. This does not correspond to
an exact count of vehicles passing the sign, since vehicles may pass the sign in a tightly packed group (or ‘platoon’); the radar is unable to distinguish individual vehicles.
Mean Speed: The arithmetic average of all the speed values recorded.
85%ile Speed: The speed at or below which 85% of the vehicles recorded were travelling.
% ≤30 mph: The percentage of vehicles travelling at speeds of 30 mph or below (i.e. the
percentage of vehicles travelling at or within the 30 mph speed limit).
% >40 mph:
The percentage of vehicles travelling at speeds greater than 40 mph (i.e. the percentage of vehicles travelling at speeds in excess of 10mph above the 30 mph speed limit).
