[sumo-user] Loaded vs Departed Vehicles

[<cch...@cs...>]

Hello,
  I would like to ask what exactly are loaded vehicles?
  From my understanding loaded vehicles are vehicles that exist in the  
simulation until it ends.
  Can I subscribe to a loaded vehicle that has yet to be departed?
  In getDepartedIds do I get the ids of vehicles that have just  
entered the simulation (just started their jurney) or I also get  
vehicles that already existed from previous steps?

  Also in python I use getSubscriptionResults() but it doesn't return  
me a dict like it says in the python
  docs.
  (example on how I use it)
  import traci

  traci.start(sumoCmd, numRetries=2, port=2500 ,label="default")
  vehicleCommands = traci._vehicle.VehicleDomain()
  vehicleCommands._connection  = traci.getConnection(label="default")

  ...
  vehDict = vehicleCommands.getSubscriptionResults(vehId)
  ^ this is not a dictionary as it says in the docs.

Thank you!
