nstallation’ height
according to offset, for a 2 m wide bicycle lane and 15° vertical angle:
O(FFSET)
0 m
1 m
2 m
H(EIGHT)
1.4 m
1.75 m
2.10 m
1.
Horizontal angle: 45° (towards the bicycles direction)
2.
Vertical angle (inclination towards the ground):
The light emitting beam must “cut” the cyclists, at the waist level or
higher. An installation at 0° (horizontal installation) is possible.
3.
Fix the screws.

ETECTION PRECISION IN FUNCTION OF THE INSTALLATION HEIGHT
,
OFFSET AND WIDTH OF BICYCLE PATH
The higher the radar is installed, the larger vertical angle of the radar to detect the cyclists and therefore the smaller the
detection Distance (D).
shows in green the possible combinations of Offsets and Width at installation height of 2 m for
a high degree of precision (97 % or more). The orange area shows the combinations of Offsets and Width for which the
detection precision will drop below 97 %.
The cyclists must “cut” the light emitting sensor beam in
order to be detected and counted. Please check the
cyclists, particularly the children, who are riding at the
side where the radar is installed are well detected. If
necessary, reduce the height of installation.
