intersections. A very powerful method of advance detection uses two simple channels: Ad-
vance and QReduce.
The Advance channel provides green extension at high-speeds for safety and efficiency.
The QReduce channel provides green extension at low-speeds when the initial queue is
dissipating.
Follow the steps below to configure the Advance channel:
1 Click on Channels-Alerts-Zones on the main menu.
2 Click the Setup Channels-Alerts-Zones button.
3 Enable a channel by checking the Enabled checkbox.
4 Select Simple from the Type drop down list.
5 Adjust the size of the zone by either using the Range (feet): up/down arrows or by
manually grabbing the zone’s blue arrows and dragging them anywhere on the road-
way.
6 Click the Speed and ETA checkboxes to activate the Speed and ETA parameters.
7 Set the speeds from 35 mph on low end to 100 mph on high end.
8 Name the channel “Advance” and click OK to save the channel settings.
Follow the steps below to configure the QReduce channel:
1 Click the second tab on the top of the Setup Channels-Alerts-Zones screen.
2 Enable the channel by clicking the Enabled checkbox.
3 Select Simple from the Type drop-down list.
4 Adjust the size of the zone to 100 to 150 feet from the stop bar.
5 Click the Speed checkbox to activate this filter and select speeds from 1 to 35 mph.
6 Name the channel “QReduce” and click OK to save the channel settings.
The OK, Undo and Cancel buttons pertain to ALL changes made in the CAZ Setup job and
not to individual channels, alerts or zones. The OK button saves the settings to the sensor;
the Undo button restores the settings to the screen’s initial values; and the Cancel button
closes the screen without saving any changes.
Priority Channel
A priority channel consists of three zones, each with a complementary role (see Figure
7.5). When any one of the three zones is active, the channel output is active (equivalent to a
Boolean OR of the three zone outputs).
