Hi,
for me the following structure works
The function runs handles one simulation, it calls traci start at the
begin and at the end traci.close
The run function is called in a loop
Do you get the error at the first or the second simulation run?
egrep -n "run|traci.[sc]" */*1c.py
315:def run(seed, gui = False, endTime = 60000):
344:traci.start(sumoCmd)
348: while traci.simulation.getMinExpectedNumber() > 0:
349:traci.simulationStep()
382:traci.close()
385: for seed in range(10):
386: run(seed, args.gui, args.last)
Regards, Harald

Thank you for your reply. I tried them but i have the following problems.
In my main function I am calling the run function that takes my input
parameters and starts the simulation.
I have defined a stopping condition that if there is no more
passengers to be served, the simulation ends.
When i use traci.start in the for loop in the main and call the run
function, none of the choices are working for relaunching the simulation.

Either:
traci.start()
traci.close()
traci.start()
traci.close()
...
or
traci.start()
traci.load()
traci.load()
....

Hello,
I am trying to simulate many consecutive sumo runs with different
inputs automatically i.e. when the first simulation ends, it will
start the other simulation from the input of the for loop.
I don't care to run the simulation in gui, I just need the output
files of every simulation.
I tried using traci.load but I get the following error:
File "C:\Users\hajjar.p\PycharmProjects\SUMO SA\Stopping cond.py",
line 178, in <module>
traci.load(["-c", "Sumo_SA_Conf.sumocfg", "--vehroute-output",
"vehroute.xml", "--tripinfo-output",
File "C:\Program Files (x86)\Eclipse\Sumo\tools\traci\main.py",
line 190, in load
raise FatalTraCIError("Not connected.")
traci.exceptions.FatalTraCIError: Not connected.
Your help is much appreciated.
Thank you in advance.
