Hi Didac,
the lane parameter is actually a lane index, so it needs to be an
integer or one of the special values like "random".
If you want to start the vehicle on a different edge you will need to
define a different route where the edge is the first one (it may consist
of only this edge).
We know that this is inconvenient, and already have a ticket for that
http://sumo.dlr.de/trac.wsgi/ticket/1129.

Michael
