Thanks again Sylvain for your quick reply. Last question:
In the context of your answer to my first question - > 1. What I meant by the directed route is the roads being one-way or two way > or the roads being major roads or minor roads. How do I return a postgis > path? > Currently I'm using the shortest_path_as_geometry() function but I read in > the readme > that I can pass to the shortest_path function if the road is directed or > not > (true/false) The current implementation of shortest_path_as_geometry makes the assumption the graph is not directed and is not using reverse cost. Modifying the pgdijkstra shortest_path_as_geometry to take into account if the graph is directed should not be a great development. Feel free to open a enhancement request on the bugzilla about it. You mean I won't be able to use the shortest_path function for my maps and I can't use it for routing purposes if the roads involved are one-way streets?
