Speed Limit
If the speed limit is zero, hardware triggering is
given always when a vehicle is detected. If the
speed limit is set, the triggering is given out
only for speeding vehicles.
NOTE! The unit is [km/h] even if bit 2 of
parameter 26 is set!

Vehicle Height Limit
Setting up height limit for Speed Limit Large,
parameter 36.
The height value is the difference between the
shortest measured value from the vehicle and
the far end of the triggering window.
For example, in a set-up where the sensor
locates 6 metres above the road and the
maximum distance to vehicles is 30 metres, a
2-metre height limit means a value of 1000 cm.
But as the measurement window does not
reach the surface of the road, typically a value
of approximately 750 is used.
The user may check the actual height values of
different vehicles by enabling ‘Height’
measurement by bit 7 of parameter 26 and
making some test speed measurements.

cover two or more lanes.

Direction Change Distance
Defines a distance after which the direction of
vehicles is opposite.
Driving direction of the first lane is defined by
bit 5 (Speed Behind) of parameter 2.
