Hi all,
I have some basic questions:
1) Why are relations preferred for bike routes?
2) In the database, how do relations apply to ways? The attributes
associated with a relation - how are they tied to ways? Will routing
software use the attributes in a relation to determine if a way is
Hi,

Because a stretch of way can belong to different routes at the same
time, and this is difficult to model without relations.

Think of it like US highways, say US26 in Portland. 26 is at times a
motorway, but it's also carried on Clay Street downtown and Powell Blvd
on the east side. The
I know that, using relations, a particular way can be part of several different
routes. Is this also true if the ways are used directly, instead of through a
relation?

Another question...
Any idea how relations would be affected if I use ArcMap's OSM Editor to
conflate roads in OSM with our regional super-up-to-date public domain data?
Would I be able to maintain OSM's unique road IDs so I don't break any
relations the roads might be a part of?
Thank you!!

Relations are preferred for /all/ routes, actually. This is because the
attributes of said route span unique ways. For example, only parts of

If there's a continuous route from point A to point B, it's easier to
keep track of it as a relation. If there's just a signed network using
bike route signs, there's no

Yes, using semicolons: lcn_ref=1;8

often have refs that belong to them (like bridge numbers) but not the

You've said this a number of times without explanation. Why does the
bridge number, or ODOT's internal referencing, belong to the way,
while the route

If it's a bicycle boulevard, it should have it's own LCN relation (even
if it does have one member), as it would also qualify as a route. And
