Creating, adjusting and deleting class bins
Figure 80. Adjusting a class bin
1
To create a class bin, press the + button at the bottom of the
Class area. Each line is one bin.
2
To adjust the parameters of a bin, click on it and use the +
and – buttons to change the value, or type a new value in. The
number that you see is the maximum length for that bin. For
instance, in the image above, the highlighted bin is for vehicles
that are between 31 and 50 feet long.
3
To delete a bin, highlight it and click the – button at the top of
the Class area.
Creating, adjusting and deleting approaches
Figure 81. Approaches window

From the lanes list on the left, select a lane you want in your
new approach.
4
Click the right arrow to move it to the approach list on the right.
5 Repeat for all desired lanes.
Definition.
A class
bin is a classification
of a vehicle based
on its length (usually
a range of lengths);
which length bin a
detection falls into
is part of the data
collected about it.
For interval data, the
sensor records how
many detections
fell into each bin
over the course
of the interval.
Note.
The first class
bin created defaults
to 120; it is the
maximum length
value and cannot
be changed. This
bin can’t be deleted
until all the others
are deleted first.
Definition. An
approach is a
grouping of lanes
used in data
collection; they
let you collect per
vehicle–based stats
you couldn’t get
otherwise, such as
85th percentile. Be
aware that adding
approaches will
increase the data
report size, meaning
the sensor can store
fewer intervals in
onboard storage.
Note.
A lane can
belong to more than
one approach.
