Setting Description Details
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.
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.
Speed Raises or lowers the
speed calculated for
all vehicles in each
lane.
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.
Length Increases or
decreases the length
calculated for all
vehicles in each lane.
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. Adjusting
thresholds impacts
the detection of
vehicles. When
adjusting, you should
not change the value
more than 2dB in
either direction at
one time. After each
adjustment, save the
settings and check
the performance of
the sensor. Contact
Wavetronix for more
information regarding
thresholds and how
to adjust them.
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.
