7.3.1.1. Classification Example 1 – Mapping Bus and Large Truck classes to digital
outputs
Example Requirement – Lane 1 Bus detection mapped to Digital output 1, Lane 1 Large Truck
detection (Truck Trailer and Articulated) mapped to Digital output 2.
As shown in Figure 19, the first two classification bins (Class 0, Class 1 and Class 3) only filter
on the selected profile class, length and speed min/max set to the extremes to ensure the ve-
hicle speed and length will not affect the classification.
In this example Classification bins 3-7 are not used and left as the default settings – min and
max speed/length set to 0, to ensure no vehicle could meet the class criteria.
Classification bin 8 acts as the Unknown class and left as the default setting. Any vehicle not
classified as within class 0,1 or 2 will be classified as class 8 (unknown class ID value of 0).

Note
The additional length/speed settings allow for further customisation on top of the loop profile
classification. For example, Class 1 could be configured for 8+1 Articulated <15m, and Class 2
8+1 Articulated >15m
