Re: [sumo-user] Unexpected Traffic Jam Occurrence in SUMO

Hi Ifezue,

according to the event-log both vehicles 5 and 6 are waiting for headway,

time 21569s vehicle 5 waits at busStop_DeltaLoop26_1_5 for 100 sec (headway)
time 21570s vehicle 6 waits at busStop_DeltaLoop26_1_5 for 100 sec (headway)
time 21570s vehicle 5 waits at busStop_DeltaLoop26_1_5 for 100 sec (headway)
time 21571s vehicle 6 waits at busStop_DeltaLoop26_1_5 for 100 sec (headway)
time 21571s vehicle 5 waits at busStop_DeltaLoop26_1_5 for 100 sec (headway)
time 21572s vehicle 6 waits at busStop_DeltaLoop26_1_5 for 100 sec (headway)

in maintainHeadway you should exclude this special situation: both buses are at the same busStop and waits for each other.

Only the second one should wait

Okay. I have attached the stop and event files for the simulation to this email. Also, the version of SUMO that I am using, just for your information, is SUMO v1_11_0+0113-90819c44001.

Thank you

Hi Ifezue,

I have tried also seed 1, but I see no jam.

Can you send me the stop and event file fpr your simualtion run with the traffic jam?

Regards, Harald

I am using seed 1, but I don't think I am using the latest development version of SUMO though. 

Could that be the issue for why its jamming on my end. Also, I usually run it in sumo gui to make sure the simulation isn't visually acting in the wrong manner.

Thank you

Hi Ifezue,

which value of seed are you using?

With the latest development version I cannot reproduce the jam.

Greetings, Harald

Hello Everyone

I am currently in the middle of simulating a specific scenario, but for some reason the lead Green bus in the image below keeps staying at the current bus stop at around the 22400 sec mark of the simulation. Is there any reason why this may be occurring? I wasn't having this issue when I simulated previous scenarios with larger buses. Why would this be occurring with smaller sized buses?

I have attached my files for this scenario to this email for reference.

Thank you for the help in advance
Ifezue
