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

Hi Michael,
It is actually buffering because the csv file is written when I close
the
simulation. However, the buffer time is infinite! even the column names
are
not written before the simulation (the connection with traci) is
closed.
The surprising fact is that the buffer time for a much larger scenario
with
many more links is about 0.07 seconds. Could it be anything else?
Thanks,
Sasan

Hi Sasan,
is it still empty after the simulation finished / got closed? If not,
it
might be simply buffering.
