Hi!
I got a new build of SUMO
and I am getting an error traci.exceptions.FatalTraCIError:
connection closed by SUMO.
The last time when I ran it
and it worked properly was
with the build from ~15.06.
(The problem already appeared
before when I used the build
from 12.07, but I left it as I
thought maybe will not occur
later.)
Traceback (most recent call
last):

FatalTraCIError("connection

traci.exceptions.FatalTraCIError:
connection closed by SUMO
I tried: „>> run your
simulation with the option
--duration-log.statistics and
--log
>> logfile.txt
>> you will find the
results in logfile.txt”
When the simulation gets this
error the log file is empty.
Worth to mention is that at
the beginning of my simulation
I set up a number for using
randomTrips.py and generate
trips file
command = 'python ' +
os.environ['SUMO_HOME'] +
'/tools/randomTrips.py -n
osm.net.xml -p ' +
vehiclesDensity +' -o
trips.trips.xml '+
'--trip-attributes=\'departLane=\"best\"
departSpeed=\"max\"
type=\"car\"
departPos=\"random\"\'
--validate'
os.system(command)
And depending on this
argument the simulation fails
or not (mostly fails..).
I would appreciate your help
on how I can find the problem.
I checked the input files and
they look fine (and works with
earlier versions)
Best,
Weronika
