Wavetronix SmartSensor HD (101-0415) - User Guide - Manual (Page 56)

CHAPTER 6 • LANES 55
arrow means the sensor is correctly positioned for optimal performance; a yellow or red
arrow means the sensor is NOT correctly aligned with the roadway.
Note
In order for the sensor alignment tool to function properly, traffic must be flowing
freely. Also, if the sensor is not already aligned close to perpendicular to the flow of
traffic, the sensor alignment tool will display a question mark indicating that the
sensor is too far out of alignment for the tool to function properly. Realign the sensor
manually and then fine-tune the alignment with the tool. After each adjustment of
the sensor, several vehicles must pass before the alignment tool's output is valid.
It may be difficult to align the sensor if there are non-parallel lanes of traffic. In this case,
mark the non-parallel lanes as Inactive or Excluded in the lane configuration screen, and
the sensor alignment tool will ignore vehicles traveling in these lanes.
Note
In cases where traffic lanes are not exactly parallel, the percentage of vehicles with
reported speeds may decrease in the lanes that are skewed.
Auto-Configuration
One of the advantages of the SmartSensor HD is the fast and simple lane auto-configura-
tion function, where the sensor automatically configures the roadway and sets up the lanes
based on passing traffic.
Follow the steps below to automatically configure the SmartSensor HD (see Figure 6.3):
1 Once the Configuration window appears, click the Tools icon and select Clear Edit
Area.
2 Click the Tools icon again and then click Restart Auto Cfg.
