Re: [sumo-user] Measuring flows in SUMO
1) I'm afraid there is no simple way. Via TraCI, you could store the edge of each vehicle from one time step to the next and then compare it with the current edge to compute the flows.
2) You can save the simulation state using traci.simulation.saveState and the reload the simulation from that state using traci.load but this is not optimized for speed. See https://sumo.dlr.de/docs/Simulation/SaveAndLoad.html

Hi!

Thank you in advance for your help!

I am struggling trying to mix Cell Transmission Model and Sumo Traffic Simulator. I have two quick questions.

1) Is there any simple way to compute the flows between one cell to another using Sumo? More precisely, can I measure the number of cars that went from one edge to another at any time step?

2) Is there any way to reverse the last step taken by the simulation using Traci? That is, going backwards in time using the python interface?

Thank you again for your help! Any information will be greatly appreciated.

Best,
Mike
