We had some insertion related bug-fixes, some of which should increase maximum possible flow whereas others might conceivably lower it. It's hard to tell what's going on in your simulation without further details. - are you using a static route file or adding the vehicles dynamically via TraCI? - are insertions the root cause of the difference between 0.21.0 and 0.19.0 or could different traffic dynamics also play a role? - how do the scenarios behave using sumo 0.23.0?
If you can demonstrate a problem in the latest release (0.23.0) such as vehicles not being inserted even though there is sufficient space, we will try to fix it. regards, Jakob 2015-07-27 12:33 GMT+02:00 <[email protected]>: > Hello sumo users, > > while running simulations with sumo-0.21 via traci, I've noticed that > vehicles insertion differ from sumo 0.19. > > Indeed, we developed a new kind of traffic light signal control and > compared it to another existing control. > > In sumo 0.19 we noticed that there is a congestion in both controls with a > scenario where the demand is high. > But in sumo 0.21, Within the same scenario, we can't reach any congestion > in one control although there is some congestion in the other control. > > By examining the simulation output trace file, we noticed that less > vehicles are inserted within one control in sumo 0.21 which explains the > fact that there is no congestion in this case. > > Is this problem known? > Is there any explanation about this problem? > > Best regards, > > Cyril > > ------------------------------------------------------------------------------ > _______________________________________________ > sumo-user mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/sumo-user > ------------------------------------------------------------------------------ _______________________________________________ sumo-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sumo-user
