| [sumo-user] traci.exceptions.FatalTraCIError: connection closed by SUMO |
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):
File "runner.py", line 376, in <module>

File "runner.py", line 265, in run
traci.simulationStep()

raise FatalTraCIError("connection closed by SUMO")
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
