I have a bunch of data for driving from point a to b and b to a (home & work). It is GPS data, so it is lat/lon & speed. I am trying to see what the data says about me, i.e. optimized time, least time waiting, total milage, etc.
I have the same sort of data, but haven't gotten to looking at it. My thoughts are to have a table of branch/merge points, perhaps obtained manually from looking at overlaid paths, but basically I know which intersections I turn at. You could do this from street data too, but it might be easier to have a more restricted set. Then, I'd convert my long paths into segments of shorter ones between branch points. I could then look at sub-path travel times, and analyze the various choices. _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
