Certain limitations can be specified for the traffic during the Traffic Detector setup, i.e. the speed limit for individual vehicles and the maximum overall road load.

If any of these values exceeds the limit, it is highlighted in red color in the Traffic Monitor (see the Auto-Intellect Software Package. The Operator Guide document), and the alarm notification window can be set to open.

2. In the object tree on the left side of the Hardware tab, select the Traffic Detector object representing the Traffic Detector module to be set up. The settings panel of the selected object will open on the right side of the window (see Fig. 7.4—202).
