[sumo-user] SUMO is encountering Fatal Error

[Ifezue Obiako <vincentobiako@xxxxxxxxx>]

Hello Everyone

 

I was running SUMO through TraCI to see if my simulation would run all the way through its intended simulation time of 61200 seconds of sim time, but the SUMO gui closed (or crashed – not sure) and I received these errors in both the command line/Python IDE when the simulation closed:

 

 

I am not fully sure what the issue is with TraCI or my Python code. I went to my Python code and added an if else statement to hopefully fix the issue but I still received the same error message. Does anyone know what may be occurring with my simulation? For reference, I have attached my Python script. If there is any other additional information or questions, please let me know.

 

Thank you

Ifezue
