CHAPTER 6 • LANE SETUP 61
2 Click on one of the range blinders and drag its edge to the desired range (refer to the
range markers on the left side of the screen).
3 Repeat Step 2 for the other range blinder if necessary.
4 Click the Restart button to apply the range blinders. When the range blinders are ap-
plied, they will turn from a red color to a dark khaki color. To cancel and use the default
ranges, or to start over, or click the Range Blinders button again.
5 After the lanes are detected and configured correctly, save the configuration by clicking
the Finished button. After clicking the Finished button, the SmartSensor will begin
storing vehicle data. The time required for configuration depends on the volume of
traffic present in the lanes, but is typically only a few minutes.
Note
After clicking the Restart button, detected vehicles (represented by moving blue
rectangles) will be displayed only if a range blinder does not cover the lane center. If
the edge of a range blinder lies between two lanes of the same road, some manual
adjustment of the gray line (usually reserved to indicate a road shoulder) may need to
be made. The edge of the road shown in the display is really a lane divider.
Manage Gain
Managing gain is an optional setting available in Automatic mode. During the automatic
configuration process, the sensor’s gain is automatically adjusted in order to best process
the radar signal at that particular installation site. In some locations the reflections from
vehicles may be stronger than in other locations, and the gain will need to be lowered in
order to optimize detection accuracy.
For the gain to be optimally adjusted by the automatic process, the sensor needs to be:
˽ Aligned almost exactly perpendicular to all the lanes of the roadway.
˽ Still configuring while several large vehicles (that return strong reflections) pass
through the beam in the lanes closest to the sensor.
In some locations, and at particular times of the day, it may be difficult to meet these two
requirements. In these cases, click the Manage Gain button to change the starting point of
the automatic gain adjustment process. The default starting point is a gain value of 5. The
adjustment process never increases the gain value; it only decreases it. The starting point is
therefore also the maximum gain value.
A new starting point will only be applied after clicking the Restart button. During the
automatic configuration process, the sensor’s current gain value is displayed in the status
bar at the bottom of the screen.
No adjustments to the gain can be made once the configuration is saved to the sensor.
