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:
Could not connect to TraCI server at localhost:55141 [Errno 111] Connection refused
Retrying in 2 seconds

How can I fix it?
