Re: [sumo-user] [EXT] Re: Playback my simulation in SUMO GUI
The simulation can never run backwards. But you can jump to a saved state in the past which is much faster than rerunning from the start.

Thank you Jakob!

 

If I understand correctly, then there is no way to go backwards on the simulation, just forward?

 

I agree that for forward I could re-run the sim but I can’t stop it and go backwards without having to restart the sim.  Am I understanding correctly?

The latest development version provides option --device.fcd-replay.file which can load an fcd-output file to replay vehicle movements. All simulation metrics should work as usual.

However, it's not necessarily much faster than running the original simulation.

An alternative is running the simulation with repeated state-saving (https://sumo.dlr.de/docs/Simulation/SaveAndLoad.html#saving_periodically)

You can then load a state file from within sumo-gui (in the 'Simulation' menu) and then run forward from this point.

Good morning Sumo user community,

 

Have a potentially silly question. Curious to learn if there is a capability I can use to play back a simulation for demo purposes.  Does the open-source tool offer a way to run the simulation and be able to play it back later, go to a time of interest in the sim, zoom in on an event or vehicle, look at metrics, keep running it, go forward, etc.? Like a video but with more capabilities on the GUI.

 

Or is there a detailed output file I could generate and open on the SUMO GUI that would allow me to do the above?

 

Thanks in advance,

 

Hector A. Martinez, P.E.
