Note. There must
be a minimum of 5.5
ft. (1.7 m) between
vehicles in order for
them to be detected
as separate vehicles;
this minimum may
increase as vehicle
speeds increase.
Note. If Direction
Protection is on,
wrong-way vehicles
will not be shown
moving across the
Verification screen.
However, they will
still be shown on the
Configuration screen.

Setting Description
Extension
Increases or decreases the
Time extension time, which the
sensor uses to prevent
vehicles with trailers from
being broken up into
multiple detections.
Direction
Determines whether
Protection
the software reports or
ignores any vehicles that
are traveling the opposite
direction in a given lane.
For example, if this is
turned on, and if a lane is
configured as moving left
to right, then any traffic
moving right to left will be
ignored (it won't be shown
on the Verification screen—
though it will be shown on
the Configuration screen—
and it won't be counted).
Set Defaults Returns all the settings for
this lane to the defaults.
3
Use the slider or the text box to change the value for that property.
4 Click OK.
Details
Adjust this setting if
the sensor seems to be
mishandling detections
of vehicles with trailers.
Increasing the extension
time will help make sure
such vehicles aren't counted
as multiple detections,
but too much can lead to
multiple vehicles being
detected as a single vehicle.
After you enter a value,
the sensor automatically
determines the extension
time and then multiplies it
by your entered value.
By default, Direction
Protection is turned on for
each lane (although if you
set a lane as bi-directional,
this setting is turned off
and can't be turned back
on from here—you'll
have to go back to the
Configuration screen).
Having it on can be useful
if, for instance, the sensor's
in an area where work
vehicles often go the wrong
direction up the road. You'll
need it off, however, to do
wrong-way detection.
