Re: [sumo-user] Prevent loaded vehicles from being inserted into the sim

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

The easiest solution is to load all vehicles at once by loading the route file with option --additional-files (see https://sumo.dlr.de/docs/SUMO.html#loading_order_of_input_files). This way, the simulation will keep running until all defined vehicles are arrived or removed.

Alternatively, you could read the maximum departure time from your input file and rewrite the condition as

 

    while traci.simulation.getTime() < maxDeparTime or getMinExpectedNumber() > 0:

I cannot replicate the issue with getDepartedIDList though. Feel free to open up an issue on github and attach a minimum failing example.

Hello,

I am using TraCI with the following while loop condition to run the
simulation until all vehicles have arrived:

while traci.simulation.getMinExpectedNumber() > 0

In my code I want to randomly prevent some vehicles from being inserted into
the simulation.
I realized that the following code causes the simulation to end early due to
the while condition:

loaded_vehicles = simulation_sub[tc.VAR_LOADED_VEHICLES_IDS]
for vid in loaded_vehicles:
   if not should_vehicle_depart():
      traci.vehicle.remove(vid)

Therefore, I am currently using:

departed_vehicles = simulation_sub[tc.VAR_DEPARTED_VEHICLES_IDS]
for vid in departed_vehicles:
   if not should_vehicle_depart():
      traci.vehicle.remove(vid)

My problem with the current implementation is that the vehicles still show
up for one timestep in the output files (vehroute-output, fcd-output,
tripinfo-output, etc.).

Is there another way of doing this to achieve the desired output?
Maybe a different while condition?

I think I have also found a small bug:
When a vehicle has departure time 00:00:00 it shows up twice in the
tc.VAR_DEPARTED_VEHICLES_IDS list.
Once after timestep 0 and then also after timestep 1.
This even happens when removing the vehicle after timestep 0!
Here an example of my logs:

After step 0
Departed list = ('10292601_3',)
Remove vehicle 10292601_3
After step 1
Departed list = ('10292601_3',)
After step 2
Departed list = ()

Thanks for the help!

Best regards
Marcel
