Re: [sumo-user] Junctions

[Michael Behrisch <oss@xxxxxxxxxxx>]

Hi Bassma,
the easiest way is to parse the network using sumolib:
http://sumo.dlr.de/wiki/Tools/Sumolib#import_a_network_and_retrieve_nodes_and_edges
For the API of the net, see also
http://www.sumo.dlr.de/pydoc/sumolib.net.html

Best regards,
Michael
