Re: [sumo-user] Teleporting car after loading a saved state
Hi,

Thank you so much for the help. May I know what part of a simulation is random? Like for what aspects of the simulation is the random number generator being used?

Your simulations diverge because
1) the primary call to traci.start sets step-length 0.5 but the call to loadState does not set the step-length
2) the simulation state does not store the random number generator by default. You can fix this by setting option <save-state.rng value="true"/> in your sumocfg

Hi,

Just wondering if you were able to run the code or not?

Hi,

Thank you for your email. I have attached a zip file below. teleporting_vehicle_v1.py does not save any states and teleporting_vehicle_v2.py saves and loads state once.

This problem has not been reported before. Please send in a minimal example scenario (either to the mailing list or attached as a zip on a new github issue).

regards,
Jakob

Hi,

I have a network where only 2 cars are travelling (for testing purpose). If I let the simulation run to completion none of cars stand too long in front of an intersection and no teleportation occurs. But when I save a state in the middle of the simulation and start the simulation again from the saved state, the cars do travel to the nearest intersection but then they get stuck there and get teleported to the next edge. They do not move even when there is a green phase or there are no vehicles in the opposite lanes. Has anybody faced this kind of problem before and know why this is happening?

For saving state I am using: 
traci.simulation.saveState('saved_simulation')
traci.close()

And for loading state:
traci.start([checkBinary('sumo-gui'), "-c", "config.sumocfg", "--load-state", 'saved_simulation']) 

I am using SUMO 1.7.0. Let me know if you want me to give you a small code for sanity check.
