satisfied with the zone settings (as viewed on the TAI display), click the Stop, Save Par , and
the Send Par buttons. Click the menu item Sensor/Write SAS Parameters to save the new
parameters to SAS-1’s non-volatile memory. For SAS-1 firmware version SAS_131 or higher,
the Write SAS Parameters step is not necessary to save the parameters to non-volatile memory in
the SAS-1.
Detection Zone/Lane Positions and Sizes may also be set or reset manually by clicking in the
Cntr and Size field for each lane. Before manually positioning each zone, click the Zones To
Edge button. Click the Stop, Save Par, Send Par and the Start buttons. This immediately sets
the zone positions to the left edge of the display and sets the zone size to 3 pixels. With all the
Blue Lines starting at the TAI display edge, it is easier to set the position and size of each zone.
Once satisfied with the zone positioning (as viewed on the TAI display), click the Stop button,
click the Save Par button, and then click the Send Par button. This sends the newly adjusted
detection zone parameters and any others which might have been changed to the SAS-1 unit.
Click the menu item Sensor/Write SAS Parameters to save the new parameter values to SAS-
1’s non-volatile memory. For SAS-1 firmware version SAS_131 or higher, the Write SAS
Parameters step is not necessary to save the parameters to non-volatile memory in the SAS-1.
Click the Start button to start the TAI display and check the position of the columns of green
“blobs” with respect to the new lane positions (as in Figure 1). Also
check the magenta
detection markers to see if all vehicles are detected (a magenta marker for each green “blob”).
Each magenta detection marker is placed in the lane or zone center for which the vehicle
detection was assigned.
In addition to the automated Lane Finder for finding and setting the lane center positions,
another approach is supported in SAS Monitor. This approach uses the Lane Finder Function as
a guide to choosing the lane centers. To choose each lane to be set, move the mouse cursor to
the Lane Finder Function display area and left click. Left click a few times and note the lane
number label in the Lanes or Zones frame. After selecting the lane to be set (Lane number
should be highlighted with a green box), right click while pointing to a peak in the LFF function.
The lane position is set to the same position of the LFF peak. Note the change in the Blue Lane
Lines on the TAI display. Continue this process to set the positions of all zones (lanes). Set the
zone size by clicking in the Size field for each zone (lane). Once satisfied with the zone settings
(as viewed on the TAI display), click the Stop, Save Par , and the Send Par button. Click the
menu item Sensor/Write SAS Parameters to save the new parameters to SAS-1’s non-volatile
memory. For SAS-1 firmware version SAS_131 or higher, the Write SAS Parameters step is not
necessary to save the parameters to non-volatile memory in the SAS-1.
Set Detection Sensitivity for Each Lane
For the SAS-1 to effectively adjust to changing traffic conditions, the detection sensitivity for
each lane must be set. Lane sensitivity (Sens parameter) must be set during Free Flow traffic
conditions. If the Start/Stop button on the main SAS Monitor and Setup display shows “Stop”,
click the Stop button to stop the current display activity.
