Hi Jakob, I have add the option numTries=100 to traci.start(),but the error is still exist.Could you please tell me is there a approach to repeat my simulation in the same traci ?Then ,I don't need to connect the server again and again,my problem solved.

Hi Jakob， Thank you,it works.But the problem is also exist,it retries for 101 times then closed and I'm sure that my computer's memory is enough.And I also occurred the error that "connection closed by SUMO",If you want more details,tell me.

[sumo-user] The reason about disconnect with Traci
Hi, My SUMO version is 0.32.0,and I write a loop to simulate for many times, I start SUMO like this: for i in range(2): traci.start([sumoBinary, "--start","-c", "data/cross.sumocfg", "--tripinfo-output", "tripinfo.xml"]) ... ... traci.close() At the beginning,it works well,but it may disconnect with traci and the time points is different.I don't know what's wrong. ___ sumo-user mailing list sumo-user@eclipse.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/sumo-user
Re: [sumo-user] Disconnect with Traci
Hi,
My SUMO version is 0.32.0,and I write a loop to simulate for many times, I
start SUMO like this:
for i in range(2):
traci.start([sumoBinary, "--start","-c", "data/cross.sumocfg",
"--tripinfo-output", "tripinfo.xml"])
...
...
traci.close()
At the beginning,it works well,but it may disconnect with traci and the
time points is different.I don't know what's wrong.

Hi,
My SUMO version is 0.32.0,and I write a loop to simulate for many times, I
start SUMO like this:
for i in range(2):
traci.start([sumoBinary, "--start","-c", "data/cross.sumocfg",
"--tripinfo-output", "tripinfo.xml"])
...
...
traci.close()

[sumo-user] Disconnect with Traci
Dear sumo-users:
I am doing a traffic light program to optimize the timing of
traffic light by using Traci.But I met a problem,I need to simulate the
process again and again,then,I got this error:

[sumo-user] The performance index 'Duration' is increasing explosively
I am trying to optimize the traffic light timings based on reinforcement learning ,but I meet a problem ,the performance index 'Duration' is increasing explosively.At the beginning,the Duration is about 8092 ms,but soon,it increased to 13 ms,and is still increasing.

[sumo-user] set phase of traffic lights
I have build a cross with straight way and turn-left way,and the cross is
like this :
[image: image.png]
and the traffic light information below:
in a time-step ,I set the phase of the traffic light in this way:
traci.trafficlight.setPhase("0",0)
traci.trafficlight.setPhase("0",1)
to let the south-north vehicles can pass the cross simultaneously,is it
correct?if I was wrong ,what is the right way to control the traffic lights?
