i am using osm2po to import osm file, into postgres/gis.
after de commenting in osm2po config file:
#postp.2.class = de.cm.osm2po.plugins.PgVertexWriter
i get a nice vertices table, with turn restrictions.
i also get a ref_count column for each vertex id.
i am trying to understand what it stands for.
initially i thought its how many times this vertex exist in the table, but quickly i discovered its untrue.
i will appreciate any help/insights as to ref_count column and its meaning.
specifically, i am trying to understand, given a target vertex, how many options for turning i have. (how many vertex and which are accessible via this vertex)
example: if im on vertex id 111, -> can access vertex id 112 and 113
i thought ref_count might help with that. (just the number of possible vertex's will be useful for me, and yes i can count it easily myself, but im curious about ref_count)
thanks for your help!
