I'm wondering how osm2pgsql determines the direction of a route.
Has the order of way-refs in the route relation influence on that?
osm2pgsql takes all the ways making up the route relation and throws
them into the GEOS LineMerge operation, documented here:
http://geos.refractions.net/ro/doxygen_docs/html/classgeos_1_1operation_1_1linemerge_1_1LineMerger.html
The result is a number of LineString geometries (at least one, at most
the number of relation members).
The direction of each resulting LineString should be the direction of
the majority of constituting ways.
Are role tags "forward" and "backward" evaluated?
Not at all.
Bye
Frederik
