That explains it. 24 hours matches the time when my flow stopped. Thanks so much for the info!

That is very likely the reason. I only set a value for "probability", "begin", "departLane" and "departSpeed". I didn't include "end", so maybe there is a default value for "end" that caused the flow to stop. I couldn't find the default values in the current documentation http://sumo.dlr.de/wiki/Definition_of_Vehicles,_Vehicle_Types,_and_Routes#Repeated_vehicles_.28Flows.29 Also, is there a way to set 'infinity' as the "end", so the flow never stops as long as the simulation is running? ________________________________ From: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> on behalf of Jakob Erdmann <[email protected]<mailto:[email protected]>> Sent: Friday, February 23, 2018 3:30:23 PM To: Sumo project User discussions Subject: Re: [sumo-user] Traffic flow disappears after some time Hello, <flows> have a fixed number of vehicles usually configured by setting and 'end' value along with another value describing flow rate (number, probability, vehsPerHour). Possibly, your flow has just run out which could be prevented by changing its parameters. regards, Jakob 2018-02-23 23:43 GMT+01:00 Jiachen Yang <[email protected]<mailto:[email protected]>>: Hi all, Has anyone encountered a situation where all the defined flows in a .rou.xml file have disappeared? In other words, the entire road network becomes empty and vehicles are no longer departing. Vehicles that my code add and remove using TraCI are still working fine, but the SUMO-controlled traffic have all disappeared. The entire simulator seems to be running as normal, just without any SUMO-controlled vehicles. I'm using all the default sumo settings listed here (http://sumo.dlr.de/wiki/SUMO), except: --lateral-resolution 0.8 --collision.action warn --no-step-log True --no-warnings True I haven't set any limit on the total number of cars allowed, and it doesn't seem like any default setting is the cause. Does anyone have ideas?
