</div></div>Dare I say it, this _is_ the right situation to use a relation. The camera nodes between which the average speed is calculated could be added to the relation in the correct order.<br>
<br>
Then again, this is the sort of detail that I'm sceptical we'll ever reach in openstreetmap in a remotely uniform (i.e. useful) way, so I'm not sure of the value of this level of complexity.<br></blockquote><div>
<br>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.<br><br>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.<br><br>

p.s. Then again again, the germans managed to map their whole power line network (?) didn't they?<br>
