<div>One point relating to Average Speed Cameras: </div>
<div> </div>
<div>Don't assume that the first camera is entry into a
monitored section and the next camera exits the monitoring.</div>
<div>This is not always the case.</div>
<div> </div>
<div>They can be set up as dual-exit-entry like this:</div>
<div> </div>
<div> Enter-A --> Exit-A-Enter-B --> Exit-B (see
<a class="moz-txt-link-freetext" href="http://news.bbc.co.uk/2/hi/7048645.stm">http://news.bbc.co.uk/2/hi/7048645.stm</a> )</div>
<div> </div>
<div>Or potentially overlapped like this:</div>
<div> </div>
<div> Enter-A --> Enter-B --> Exit-A --> Exit-B </div>
<div> </div>
<div>So the best we may be able to do is note the presence of
the cameras. Attempting to place them in relations for the
individual monitored sections could be tricky and misleading.</div>

This is not really an aspect of mapping which interests me: I'm
mainly aware of it, because a local mapper is and has mapped such
areas. Here is one example:
<a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/browse/relation/78922">http://www.openstreetmap.org/browse/relation/78922</a><br>
