Re: [sumo-user] reading laneData using socket connection and xml2csv.py

Sasan

Hi Sasan,
those buffers are usually not time triggered but are flushed to the
output when they reached a certain amount of data.
You may try to add some calls to flush() in the xml2csv script and also
on the sumo side.

Best regards,
Michael
