My setup for my web page is OpenLayers, Postgresql/postgis and pgrouting.
What I do not understand is how I am going to do the routing.I have read many tutorials but I don't understand what my next step will be.
So I have downloaded an shp file of osm data into my computer and imported the 'roads.shp' into my database. In the database, I have also all of my bus route stops as tables of points.
How do I use pgrouting from now on? What algorithm to use and how to create the topology? Do I need to merge the roads shp with the tables of the bus route stops ?
For additional info please don't hesitate to ask!
