Relations don't really seem to be necessary really. Responding to a later
comment. Average speed cameras can monitor a network of roads so one can't
assume that there is an order in which a vehicle will pass the cameras.

Surely a simple fag such as 'speed_camera=average' to the relevant highways
would be the logical. One could then add details such as
'speed_camera:type=Specs' or whatever. After all, the speed limit is on the
way. Possibly the best tag would be 'maxspeed:enforcement=average'. That
might work well.
