Fyi, I have up-loaded images from a couple of places in the UK where Stop Areas/Stop Places are used. Notice that in some places there are nested stop places. For our purposes we can consider Stop Place and Stop Area to be referring to the same thing, however the correct technical term in CEN for the stuff on the ground is a Stop Place.</div><div><br></div><div>London</div><div><a href="http://www.flickr.com/photos/peterito/3584182693/">http://www.flickr.com/photos/peterito/3584182693/</a></div><div><br></div><div>Leeds</div><div><a href="http://www.flickr.com/photos/peterito/3584989420/">http://www.flickr.com/photos/peterito/3584989420/</a></div><div><br></div><div>There are times when the hierarchy is useful - for example one might first ask to go from Manchester to London, and then be offered routes from Manchester Piccadilly or Manchester Oxford Road to London Victoria Coach Station or London Euston, and then finally when one has chosen the actual journey one might be told to use Platform 10 from Manchester Piccadilly Railway Station. Similarly for large bus/coach interchanges. For some bus/coach/rail interchanges one doesn't actually know which Access will be used until shortly before the vehicle departs so one can only give the station itself as the starting point.</div><div><br></div><div>I do think that if we should accommodate this richer information where it is available and where people want to built it and then people will start using it for creative things, such as reducing the clutter on zoomed out maps (Google just ignores bus stops as one zooms out to stop it getting unmanageable, something which would not be ok for a bus-centric map).</div><div><br></div><div>We could also consider using tools to automatically build stop places and associate Accesses with Stopping Places to stop it being too complicated for mappers.</div><div><br></div><div><br></div><div>Regards,</div><div><br></div><div><br></div><div>Peter</div><div><br></div><div><br></div><div><br></div><br><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate;
