Re: [sumo-user] No statistical output file while using Traci

Thank you for your response Jacob. I already have as my last command in my script the Traci.close(). By using sumo gui everything works perfectly. What am I missing?

Best regards,

Thodoris

make sure to call traci.close() at the end of your script (The peer from that error message is your python script which suddenly shuts down).

Greeting everyone,
I am using traci commands through a python script in order to run some simulations. My sumo version is 1.2.0. The problem is that after simulation ends with the command traci.close() i get a non fully written statistical output file. I only get the coming lines:

***Starting server on port 42389 ***

Loading net-file from '../../../../.net.xml'... done (13ms).

Loading additional-files from '../../../../.add.xml'... done (12ms).

Loading done.

Simulation version 1.2.0 started with time: 0.00 

In the error log i get Error: tcpip::Socket::recvAndCheck @ recv: peer shutdownQuitting (on error).

The strange thing is that if i run the exact same script but using the sumo-gui the output files are fully writen.

My configuration file:
