Hello, me too am new to / working on that osm routing issues and have some general questions: How does the data preprocessing work? OSM has been for visualizing i.e. there are a lot of (for routing) unnecessary nodes (of degree 2) Also with inter-city-directions it seem unnecessary to 'visit' all the minor non-motorway-roads Are there any approaches to 'normalizing' or 'layering'? (like freeway- / primary- / secondary Graphs)?
Though pgrouting for instance is quite fast as it uses BGL "inside" the database (please correct me if I'm wrong) it has to load the graph data structure for every request again and again, which slows it down A graph of just 'connected motorway-junctions' would take much less space to always keep in memory.. I can't find anything in that direction and would be happy about some pointers or conversation. Thanks. flo > _______________________________________________ > Routing mailing list > [email protected] > http://lists.openstreetmap.org/listinfo/routing > > _______________________________________________ Routing mailing list [email protected] http://lists.openstreetmap.org/listinfo/routing
