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.
Currently , due to a bug, a Average speed control should always start at the A point of a segment. In case of a two way average speed control it may be necessary to split a segment in two parts, change the A and B points of the newly created segment with as result that from both ways the average speed control can be defined on a segment starting with an A point. The A-point triggers the warning message.
