Certain limitations can be specified for the traffic during the Traffic Detection 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 Using the Traffic Monitor interface object), and the alarm notification window can be set to open.

To specify the traffic limits, do the following:

1. Go to the Traffic Detection object settings panel.
   
2. In the Speed limit, km/h field (1), enter the maximum allowed driving speed.

3. In the Traffic jam threshold, % field (2), enter the maximum allowed road load.

   The road load parameter is calculated using the following formula:  , where  is the time during which the vehicles were in the coverage area of the Traffic Detection software module for the statistics update period, and  is the total operating time of the Traffic Detection software module for the statistics update period (see Setting up the update time and period for displaying statistics).

   
   

4. Click Apply (3).

The traffic limitations are now set.
