<br>Hi all<br><br>I don't if it's the best way to do this, but I faced the driving direction (and distance) issue by writing a pl/pgsql function in which, with a cursor, I compare every couple of linestring into the routing query result to calculate the directions and calculate the partial and total distance.<br>
