Figure 7.7 – Providing Dilemma Zone Protection

By providing zones for level-one priority dilemma zone protection, level-two dilemma 

zone protection and queue clearance, a priority channel provides exceptional detection 

from start-of-green to end-of-green.

Note

There may be a number of uses of the discovery range feature for other applications 

than truck priority. For example, you could require that a vehicle be discovered at a 

certain range (using the discovery range threshold) and that it travels to a down-

stream zone several hundred feet away before it activates a channel output. This is 

a way to know that we have tracked a specific vehicle over an extended range. This is 

better than simple using the channel delay because it isolates a single vehicle.

Normal Channel
