| Re: [sumo-user] Error: bad allocation |
Hi Sharif,
I'll try out the new files tomorrow. Just a short but important notice: "--random 1" will lead to quite the opposite you want, as it initialises the RNG with the system time. To choose a start seed yourself, use "--seed INT" where INT is the chosen number.
Best regards

Hi Mirko,
Thank you so much for your help, I truly appreciate it. Attached is the script to run the simulation. If you run the script it will give you the error. I have also attached the required files and for network and route file and signals setting, you can download from the github I had previously shared.
I get the error at after about 20 minutes and at traci.simulationStep(). Additionally, with the SUMO v1_17_0+0578, the code on line 38 "float(traci.vehicle.getStopParameter(taxi_temp,0,'started'))" was working but now updating the SUMO to SUMO v1_18 the function gives error. Can you please also check this.
Also, I want to make the simulation deterministic but still when I check the tripinfo file the departSpeed and timeloss for vehicles in the route file is always different. I am using --random 1 to make it deterministic.
Many thanks and please let me know if anything else is needed.
Best regards,
Sharif

Subject: AW: [sumo-user] Error: bad allocationHi Sharif,
could you please either add all files referenced when calling sumo (vehicle types, demand, ...) or cut down to a version which still exhibits your problem with the least extra data possible? I cannot run the simulation as some input is missing.
Best regards
Mirko

Hi Mirko,
Thanks to Harald and you. I tried with SUMO 1.18 and this time I didn't get bad allocation error for the same scenario, instead this time the connection closes at traci.simulationStep() in a different scenario. Attached is the trace log file and error screenshot and also I am using the Ingolstadt model which is available on github: https://github.com/TUM-VT/sumo_ingolstadt.
Best,
Sharif

Subject: Re: [sumo-user] Error: bad allocationHi Sharif,
as Harald already mentioned, there may be some internal problem in SUMO causing the memory error. Could you please share a preferably small scenario to reproduce your error? In case you use the TraCI Python interface but do not want to share your custom script, you can generate a log of your TraCI calls instead.
Best regards
Mirko

Thanks for reply. I am using Windows OS and the development version of SUMO v1_17_0+0578.
May be somebody else can answer this question.
additional comment, why taxi skips a stop when forced to be teleported due to whatever reasons. Isn't it better to be teleported to the next assigned stop instead to the very last scheduled stop. Currently, I assume that when taxi is assigned to a request, the taxi is assigned two scheduled stops, one at the pick-up point and other at the request drop-off. Later, when the taxi is forced to teleport, it is teleported to the very last scheduled stop and maybe causing the bad allocation error. please correct me if my assumption is wrong. 😊
Many thanks and have a great day.
Best, Sharif

it seems to be an internal memory problem in SUMO.
Which version of SUMO and which operating system are you using?
Best Regards, Harald

I am running simulation using traCI to assign taxis to requests and at some point, in the simulation the taxi is teleported and skips a stop at a lane where it has to pick the request. Now, this behavior gives an error stating "Error: bad allocation" forcing the simulation to close. Attached is the screenshot of the of the message.
Many thanks for your response.
Best,
Sharif
