[OSM-talk] Should Bridges be independent of their ways?

[Peteris Krisjanis]

Problem is rather simple with this actually right on target aproach -
current practice and "it is too damn boring and difficult" or is also
known as "death by thousand paper cuts".

I like micromapping - I hate current quality of routing software and I
think there is whole posibility to have it more precise and "smarter".
For that we need precise maps (for all kind of traffic at least).
However let's admit - it is currently available only on selected
regions, cities or even districts of cities or towns. So move from
"highway" tag (who only last year have found solid ground to work on)
to seperate lines + relation ASAP wouldn't be very smart for now.

Maybe this need a vision bigger than one proposal? I would suggest a
plan with points to move slowly forward to posibility to have maximum
features to do micromapping.

I would vote for using highway as usual for places where is no
difference, and where it comes to split, split off seperate lines
(tagged as lines=1) with clear indication which is which.

Then we could go futher with discussing how to reform ways/lanes.

However, it doesn't change a original topic - I would like to see
bridges as seperated physical entities with different ways on the top
of it. It *is* wierd when two lines on the bridge are seperated.

Just my thoughts,
Cheers,
Peter
