Re: [sumo-user] Adding multiple clients to the SUMO dynamically.

[Michael Behrisch <oss@xxxxxxxxxxx>]

Hi Satyam,
there is at least subscription code in the traas sources but I don't 
know of any exmaples and did not try it myself. The documentation 
http://traas.sourceforge.net/cms/index.php?id=documentation says it is 
not supported, but I am forwarding this to the mailing list and the 
original TraaS author, maybe someone there can help.

Best regards,
Michael
