INSTALLATION
RADAR INSTALLATION - RED LIGHT ENFORCEMENT (RECEDING FLOW)
The nature of the design of the radar lends itself to
versatility in its mounting on the roadway. There are
however, factors to be considered when siting the
radar to ensure optimum performance is achieved.
The radar should be installed at an angle of
approximately 20º from the pavement line and sited
toward the centre of the junction area. The area to
be enforced should be within the ‘D1’ range of the
radar (85 metres max). Mounting height should
be approximately 3 metres from ground level.
Offset (setback) should be approximately 2 metres.
Declination angle of the radar head should be
approximately 10º.
Care should be taken to ensure that the area of
interest is covered by the 40º field of view, this can
be affected by mounting height, correct mounting
angle to the road, correct declination
angle and the radar offset.
