Take the 2-minute tour ×  I have two tables: one, the resulting
table from converting osm.xml via osm2po so I can use pgRouting,
and another one that contains information on what edges each
public vehicle passes through (|vehicle_code|edge_ids|). Note:
one edge_id might contain many public vehicle codes.  So after
executing pgRouting shortest path query, I want to know which
vehicles are the best to use to navigate the shortest path to
avoid too many transitions.  I'm kinda new to SQL; please help.
Thanks!  share|improve this question  Your Answer    Browse
