Count Unit Weighting Factor
The weighting factor is used to
define the number of counts
required to cause the reply bit to
change state. The data is
selected using the table below.
The value used depends on the
maximum vehicle flow rate at
each count site. Generally a
weighting factor of approximately
twice the maximum flow will be
required.

Occupancy Unit Weighting
Factor
This is used to define the number
of internal counts required to
cause the reply bit to change
state. The value is selected using
the table above (see GCF
command). The internal count
rate is 25 Hz for 100% occupancy
so a weighting factor of 6 is
normally used, giving a change of
state every 1.28 seconds max.
Default: 6
