Classes
Usually the following 7 classes are supported:
Pedestrian, Bicycle, Motorbike, Passenger Car,
Transporter, Truck/Bus, Long Truck
I
May affect max. detection range. Occlusion needs to be considered.
II
Smaller absolute angles allow longer detection range along a road.
III
Application specific. Gantry mount: steeper el. angle possible, with limitations of maximum range. Negative
elevation angle means sensor pointing towards road.
IV
Typical value for counting applications; may be different for other applications.
V
Typical value when properly installed at suitable location. The counting and classification accuracy typically
depends on the following main (and other) factors: mounting height, traffic density
The sensor is typically used standalone. Multiple (up to four) sensors may however be used
in close vicinity using separate configurable frequency channels, avoiding mutual
interference.
The cycle time is set to 75ms.
