Setting Up Zones

The first recognition zone (hereinafter - the entry zone [towards the intersection]) should be located directly behind the stop line (violation of the "exit for the stop line" on red light) and not "exit" into the intersection of roads.

The second recognition zone (hereinafter - exit zone [from the intersection]) should be located behind the intersection of the same direction of traffic.

It is possible to assign the same zone to several adjacent lanes.

Entry zone ( to crosswalk )

Exit zone ( from crosswalk )

Some tricks

Now you’re done.

Average Speed

General Information

Average speed measurement requires two cameras connected per each route.

Speed measurement accuracy correlates with distance measurement accuracy.

Connect cameras and set up recognition

Adding a route

Navigate to Settings > Traffic rules > Average speed. Click Add to add a route.

Assign Road name, select channel/zone pairs for Point1 and Point2, set distance between points in meters, and set speed limit in km/h.

Measuring distance

The shorter the distance between cameras the more important it is to have the real driving distance measured.

For both of channel/zone note the point on the ground that lays on the zone boundary the vehicle crosses when entering the zone. In an example below this boundary is the bottom one stretching between vertices 3 and 4.

Measure a driving distance between the noted points.
