The Traffic Detector Detection module is able to detect the emergence of traffic jams on the road. The module generates a specific event and, in certain cases, notifies the operator.

...

To set up the jam detection parameters, do the following:

1. Go to the Traffic Detector Detection object settings panel (2).

2. In the Beginning time, s field (31), enter for how long (in seconds) the jam conditions must be satisfied for the start of the jam to be detected.
3. In the Ending time, s field (2), enter for how long (in seconds) the reverse jam conditions must be satisfied for the end of the jam to be detected.
4. In the Average speed threshold, km/h field (43), enter the average traffic speed:
   • If the average traffic speed is lower than this value, then a traffic jam may be detected (if other conditions are satisfied).
   • If the average traffic speed is higher than this value, then a traffic jam may be considered to have ended (if other conditions are satisfied)

5. In the Traffic jam threshold, % field (54), enter the road load (in percent):

   • If the road load is higher than this value, then a traffic jam may be detected (if other conditions are satisfied).

   • If the road load is lower than this value, then a traffic jam may be considered to have ended (if other conditions are satisfied).

     Info
     title Note.
     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 Detector Detection software module for the statistics update period, and  is the total operating time of the Traffic DetectorDetection software module for the statistics update period (see Setting up the statistics update time and period for displaying statistics).

The jam detection parameters are now set.
