Re: [sumo-user] Using flows after loading a simulation state

[Jakob Erdmann <namdre.sumo@xxxxxxxxxxxxxx>]

Hello Jakob,

the aforementioned bug is fixed in the latest development version. When loading simulation state that contains flows, make sure to load the original route files that were used when saving the state. You do not need to manage begin and end time as this is handled by sumo. Just define your flow as

<flow id='South_to_North_Car_0' from="-2000000.0.00" to="-2013000.186.34" begin='0' end='3600' vehsPerHour='1800' type='CarDistribution' departLane='random' departPos='base' departSpeed='max'/>

regards,
Jakob

Hello Jakob,

yes, this is a bug (https://github.com/DLR-TS/sumo/issues/3971).

It should not be necessary to load flows again after saving.

Thank you for bringing this to my attention.

regards,

Jakob

Hello everybody,

I’m already bothering you with my next question. I tried creating a saved simulation state and reloading it afterwards, which works in principle, but it seems I can’t use flows afterwards anymore, but would have to define every vehicle explicitly. Is that correct?

A part of my demand definition looks as follows:

This would be before saving the state:

<flow id='South_to_North_Car_0' from="-2000000.0.00" to="-2013000.186.34" begin='0' end='100' vehsPerHour='1800' type='CarDistribution' departLane='random' departPos='base' departSpeed='max'/>

And this after:

<flow id='South_to_North_Car_continuous' from="-2000000.0.00" to="-2013000.186.34" begin='110' end='3600' vehsPerHour='1800' type='CarDistribution' departLane='random' departPos='base' departSpeed='max'/>

So basically, I got the same flows again with a different name and create more vehicles after the state is loaded. However, I receive an error message that the first vehicle with the ID South_to_North_Car_continuous.0 has no valid route.

Is this a bug or is it simply not possible to create flows after the simulation has already begun?

Thanks

Jakob
