A limitation of the detector is that only two sets of class definitions can be made, these are
applied to loop1 and 2, and loop 3 and 4. In single loop mode it is only possible to define two
classification definitions.
When configured for single loop classification the class definitions for lane 1 apply to loop1
and loop2, and lane 2 to loop3 and loop4.
The available classification options allow the vehicle speed and length to be used as criteria
for defining a vehicle class. A vehicle meeting a class definition causes an internal class de-
tect event which may be assigned to physical output as required. The class detect and vehicle
detect events can be individually assigned to the physical outputs and GSPI.

7.3.1. Mapped Classification
The mapped classification (classification bins) config tab, as shown in Figure 18 allows up to 9
classification bins (also referred to as class) to be mapped. The ‘Mapped’ setting shown Figure
17 must be selected to use this feature. Each bin has a Class ID which can be used to customise
the classification value reported in the vehicle data.
Figure 17 : Classification Mode Selection (General Tab)
The classification bins can be configured in terms of min/max length and speed, and vehicle
profile class (TLS vehicle classes), or a combination of both. The bins can be mapped to the
digital outputs, as shown in, it is possible to map several classification bins to a single output
if required. It is also possible to configure classification bins which overlap, if a vehicle meets
