| Re: [sumo-dev] emissions whilst trying to exit from parking |
A benefit of having notifyIdle would be that it could also handle the case of vehicles being delayed on initial insertion. But it is a complicated thing to do because those vehicles may not have decided yet on which lane to start so you cannot give the right MoveReminder to them beforehand. Also it is not clear whether this case should be handled identically to ending parking. So if you found a method without MoveReminders just go ahead and we are looking forward to the pull request :-) Best regards, Michael Am 26.02.20 um 21:50 schrieb The div: > Thanks again jakob, I guess you don't sleep ;) > > After sleeping on it I realised I didn't need to kludge the > movereminders - just iterate over the lane movereminders - seems fine. > > I just need to cross check the computed emissions are equal across all > the outputs. > > Cheers > Div > > > > > > > -------- Original Message -------- > On 26 Feb 2020, 08:09, Jakob Erdmann < namdre.sumo@xxxxxxxxx> wrote: > > > Thanks for the thoughtful discussion, > > - Adding MSMoveReminder::notifyIdle sounds reasonable but l'll have > to discuss this with @behrisch who designed the MoveReminder > architecture and may have further ideas about it. > - I would call the new method MSVehicle::workOnIdleReminders (I > analogy to workOnMoveReminders) because it might be used for other > things besides emissions (https://github.com/eclipse/sumo/issues/2233) > - I think it would be ok to let parking vehicles keep their > moveReminders and let MeanData handle notifyIdle.
