NSTALLATION PLACE SELECTION
3.2.1
Detection range
The radar’s detection range depends largely on the shape of the objects and on the interfering
reflections in the environment. In general, the larger the reflecting area, the higher the detection
range. The more objects in the measurement lobe, the lower the detection range. This is also the case
for tree branches and bad weather conditions (heavy rain).
The average range, measured on a straight and flat road is 80 m for little cars, 100 m for standards
vehicles and more for large vehicles and lorries. The best range is reached with an installation at 1,50
m to 2,50 m height (lower edge of the display panel).
3.2.2
Installation and measuring angle
The best measurement angle is along the lane axis, which would mean installing the display in the
middle of the lane. Since this is obviously not feasible, install the display on the pavement between 1.5
m and 2.50 m height.
The mounting system at the backside of the display allows it to be mounted on existing lighting or
signalling poles, with standard collars. If the range is not sufficient, you have to orientate the display
so that the detection area of the radar points to the vehicles driving towards it. The angle with the lane
must be as small as possible.
The indications are given for a flat road and a vertical pole. If
the angle between the road and the installation pole is not
90°, please compensate the slope or the pole tilt.
