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(20000): 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.
