INSTALLATION
RADAR INSTALLATION - RED LIGHT ENFORCEMENT (ADVANCING 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.
