<div dir="ltr">Warin's example is good. A couple of other points to consider ...<div><br></div><div>1) The "via" tag can be useful. Take a look at Line 5 in Lancaster. Sometimes it goes "via" Chestnut and sometimes "via" Pleasure, but never both. </div><div>2) If the line has a designated destination, I'd use that. Again, looking at Line 5, the named destination is "Grandview/Rossmere". Looking at the actual stops, it seems to me that "Rossmere" is a "via" and "Grandview" is the actual destination. Looking further, it seems that the Lancaster Shopping Center is the consistent point, so I would make two relations, one "to" Lancaster Shopping Center (Grandview) and the other "from". </div><div>3) Again on the same line, there is a way that is actually traversed twice in the SAME direction, the short part after leaving Michaels. This can be mapped. (See, for example, <a href="http://www.openstreetmap.org/relation/5849581#map=17/31.63434/-8.00037">http://www.openstreetmap.org/relation/5849581#map=17/31.63434/-8.00037</a>, where <a href="http://www.openstreetmap.org/way/389916567">http://www.openstreetmap.org/way/389916567</a> is traversed twice in the same direction.)</div><div><br></div><div>For Lines 1, 2 and 3, I'd mark them as "to" Park City A (or B or C), with a "via". For instance, Line 1 would be to (or from) "Park City A" via "Southeast" with a terminus at Park City.<br><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Oct 1, 2017 at 7:07 AM, <span dir="ltr"><<a href="mailto:tagging-request@openstreetmap.org" target="_blank">tagging-request@openstreetmap.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>

I'm in Lancaster, PA right now and would like to add the Red Rose Transit<br>
<<a href="http://www.redrosetransit.com" rel="noreferrer" target="_blank">http://www.redrosetransit.com</a><wbr>> bus lines to OSM. The network is made up of<br>
six "City" lines, serving destinations close to the city, and 11 "County"<br>
lines, which are radial routes to nearby towns with stops along the way.<br>
(An interactive map of each route can be found here<br>
<<a href="http://busfinder.redrosetransit.com/Infopoint" rel="noreferrer" target="_blank">http://busfinder.<wbr>redrosetransit.com/Infopoint</a>>.<wbr>) What I'm confused about<br>
is how to properly map the relations of the City routes based on the<br>
information in the wiki page<br>
<<a href="http://wiki.openstreetmap.org/wiki/Public_transport" rel="noreferrer" target="_blank">http://wiki.openstreetmap.<wbr>org/wiki/Public_transport</a>>.<br>
<br>
The page says that each direction of the route should be a separate<br>
relation. For the County routes such as Route 10/Lititz<br>
<<a href="http://www.redrosetransit.com/wp-content/uploads/2017/08/Route-10-all-8-28-17.pdf" rel="noreferrer" target="_blank">http://www.redrosetransit.<wbr>com/wp-content/uploads/2017/<wbr>08/Route-10-all-8-28-17.pdf</a>>,<br>
this is easy (though I'm still figuring out how the system's forks work).<br>
Since the Queen St Station is the hub of the entire network and serves as<br>
the starting point for most of the routes, I'd have a relation for the<br>
outbound direction that starts there and ends at Lititz, and another<br>
starting and Lititz and ending at Queen St Station.<br>
<br>
However, the City routes aren't so simple. All of them are effectively<br>
loops that start and end at the same place, but have significant overlap<br>
with itself in the other direction. For most such as Route 1/Park City A SE<br>
<<a href="http://www.redrosetransit.com/wp-content/uploads/2017/08/Route-1-8-28-17.pdf" rel="noreferrer" target="_blank">http://www.redrosetransit.<wbr>com/wp-content/uploads/2017/<wbr>08/Route-1-8-28-17.pdf</a>>,<br>
they start at Queen St, go out toward one destination, come back to the<br>
other side of town to a different destination, then come back toward Queen<br>
St. It effectively makes a very misshapen figure 8. Neither far end of it<br>
really serves as a terminal, but rather a prominent station, of which there<br>
are several along every route.<br>
<br>
What's the best way to map something like this, where the beginning and end<br>
are the same place, making it a one-way loop that overlaps itself? I<br>
suppose it all boils down to how to deal with this kind of situation:<br>

Take a look at<br>
<a href="http://www.openstreetmap.org/relation/7258397#map=15/-33.7219/150.3061" rel="noreferrer" target="_blank">http://www.openstreetmap.org/<wbr>relation/7258397#map=15/-33.<wbr>7219/150.3061</a><br>
<br>
Starts and ends at the same place.<br>
<br>
Has loops where it travels on the same road in both directions.<br>
<br>
That help?<br>
