Some people advocate nodes off to the side of the way<br>to represent the location of the pole or shelter in relation<br>to the road.<br><br>Near where I live (Korea) there is often a shelter on<br>one side of the road for buses going both directions.<br>
In that case I'm guessing I would put a shelter node<br>on one side of the road and a node that is not a shelter<br>on the other side.<br><br>How do I relate these nodes to the way? I don't<br>like the idea of short segments perpendicular to<br>
the way.<br><br><div class="gmail_quote">On Thu, Apr 24, 2008 at 1:45 AM, Peter Miller <<a href="mailto:peter.miller@itoworld.com">peter.miller@itoworld.com</a>> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
The EU standard Transmodel defines a Stop Point as 'A POINT where passengers<br>
can board or alight from vehicles'. For bus stops this means a single pole,<br>
shelter etc and for a place where there are three poles for different<br>
services close together then there would be three entries.<br>
<br>
There are also places where buses stop where there is no physical<br>
infrastructure but where buses stop which also need Stop Points. In rural<br>
areas there might be a pole on one side of the road but buses stop in both<br>
directions, or in some places there is not infrastructure on either side of<br>
the road.<br>
<br>
For there are a number of Stop Points close to each other then these can be<br>
grouped into Stop Areas that are 'A group of STOP POINTs close to each<br>
other'. I suggest that we achieve this with a relationship call a 'Stop<br>
Area' is people are keen to model it.<br>
<br>
For railway stations it can get more complicated as a platform can be made<br>
up of sub platforms (long trains stop at platform 4 and two short ones can<br>
stop at 4A and 4B etc). In this case I believe there should be a Stop Point<br>
for 4, 4A and 4B.<br>

<br>
This interpretation is now being discussed as ISO level so is probably the<br>
one to go with.<br>
<br>
Are we agreed that this is the appropriate interpretation for the feature<br>
going forward. In which case shall I add this clarification and<br>
interpretation to the relevant OSM tag page?<br>
<br>
Btw, Someone might like to ask the DfT in the UK at some point for a copy of<br>
the DB they have with the location of over 350,000 bus stops with their<br>
names and the name of the associated street. I know the people but it might<br>
be better if it came from someone else, possibly from the foundation?<br>
