Dynamic Density

e Dynamic Density parameters determine the number of trackers that are required to

meet the specied level of eciency.

Figure 8.15 describes the text displayed when the Qualied Count is lower than, equal to,

or higher than the Dynamic Density thresholds. e number of qualied detections is fol-

lowed by a percentage number. e percentage is the count ratio of the current number of

qualied detections divided by the DDCR (see Figure 8.16).

e zone output will be activated when the count ratio is equal to or greater than 100 per-

cent. e percentage is displayed in the roadway display to help you tune the Dynamic

Density parameters and extend the green light when desired.

Note

It is recommended that you adjust the Tuning Factor instead of the Headway and

%Utilization parameters.
