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. Regards, Peter > > > robert. > > p.s.
