Average Speed Cameras
Check on all road segments where average speed cameras are operational the 
Average Speed Camera check boxes. If a ASC zone starts or ends in the middle of an existing (longer) segment, you may have to add a new node (by splitting the segment), to get the ASC notifications to start / end at the correct locations. If the start/end is approximately 20m from an existing node, this is not necessary.
If the cameras are already placed but not yet operational use dummy camera's.
