Setting Description
Volume Adjusts the aggressiveness
of traffic radar–specific
algorithms.
Detection Raises or lowers the
thresholds for detecting
vehicles. It lets you
determine how large a radar
return must be in order for
the software to define it as a
vehicle detection.
Speed
Raises or lowers the speed
calculated for all vehicles in
each lane.
Length
Increases or decreases the
length calculated for all
vehicles in each lane.
Details
Adjust this setting if you
observe a count accuracy
problem. Adjust the
percentage up to increase
the number of detections
and down to decrease.
You'll likely need to adjust
at least 10–15% in either
direction (possibly much
more); adjusting less may
not impact detections. We
recommend you keep the
slider between 20 and 190%.
Adjust this setting if you're
having a problem with
multipathing—by raising it
a little, you may be able to
weed out false detections.
But raising it too high will
begin to weed out real
detections as well.
Increasing the decibels
raises the threshold and
results in fewer detections;
decreasing lowers the
threshold and results in
more detections.
Adjust this setting if speeds
are consistently too high or
too low. After you enter a
value, the sensor calculates
the speed of each detection
and then multiplies it by
your entered value.
Adjust this setting if lengths
are consistently too big or
too small. After you enter a
length, the sensor calculates
the length of each detection
and then adds or subtracts
your entered value to it.
Note. Each of these
settings affects only
the lane you clicked on.
Note. Since the
occupancy metric
reported in the interval
data is calculated
using length, a change
in this parameter
will also change the
reported occupancy.
