Hi Olivier, Stephen used pgRouting and implemented driving directions. You can see his demo here: http://gis.imaptools.com/routing/leaddog/?zoom=10&lat=33.85667&lon=35.52978&layers=B0TTTF&start=35.492313%2033.826188&stop=35.595811%2033.906827&method=STS&lang=eng
The problem with driving directions is, that its implementation depends very much on the data you have. For Japanese data for example road names are usually missing, so you need to think about a different way how to describe the route. Also some data sets provides more some data sets have less attributes. pgRouting is "only" the library to provide shortest path search functions. Here is a wiki page about driving directions of the OpenStreetMap project. http://wiki.openstreetmap.org/wiki/Sample_driving_instructions If you're going to use OSM data, this might be helpful. I must admit that some instructions on the pgRouting wiki regarding driving directions with different data sets would be nice.
