[Talk-us] Interstate Highways Relations List

[Apollinaris Schoell]

this is nice, will add what I have done already.

some comments for discussion.
did you change the recommendation for a reason compared to the one here?

not that this is perfect but it has more information.

both definitions should be consistent and correct a few things. a list  
of corrections I would like.
- with API 0.6 the size of relations is limited to 1000 members. many  
interstates have more segments. relations have to be split into  
smaller pieces and a "super" relation.
- direction: ideally 2 relations instead 1. interstate signs,  
direction signs and navigation systems show the direction. osm data  
should contain it in the same way.  map rendering should ignore  
direction. just the interstate sign is sufficient. same as on Garmin,  
Google, Yahoo maps.
- ref: I tend to use the full ref like "I 80" same as we set it on the  
way. Simply to have it consistent and switching the renderer from  
using way ref to relation ref will not break the whole map. the  
additional redundancy will not blow the database.
- name: all maps and also the tiger data has names for many motorways.  
but I have rarely seen any sign using the names and directional signs  
will always use the I XXX, US XXX, State XXXX notation. navigation  
systems should use same notation as signs.
my proposal is to keep the names on the way and set the name on the  
relation to the name used on signs. As a nice side effect josm will  
show the name and it's easier to work with many relations loaded the  
same time. oops we don't map for the renderer, editor but why not make  
life easier
