Re: [sumo-user] Save state does not work properly
The problem is fixed in the latest development version. You can obtain it tomorrow at https://sumo.dlr.de/docs/Downloads.php#nightly_snapshots or next week in the official release of 1.18.

Thank you for the inputs. The bug is now being tracked at https://github.com/eclipse/sumo/issues/13449

Jacob I have attached a mini example of how I save the state. Also, I noticed that there are saved vehicles that have depart time after the saved state duration. For example, in the provided script I run the 
simulation until 900 sec and I save the state and inside there are vehicles that depart after 900 sec.

Best regards,
Manos

In my own test, saving and loading state with routeDistributions is working and I have no idea how arrived vehicles and up in your state file.
If you could provide an example (i.e. sumocfg, traci script, xml input files) for reproducing the unusal state file, this would greatly aid in fixing the problem.

Hi Jakob,

sorry for replying here but I know what is happening. Until the point I run my simulation I have 319 arrived vehicles. As far as I can understand those vehicles should not be stored in the state file (they also don't have a trip info device).
Moreover there are exactly 319 "broken" routeDistribution tags (the ones that correspond to the arrived vehicles). Because I used SUE (max alternatives = 5) in one distribution I may have 1 or more (until 5) possible
routes. I give an example of a broken routeDistribution:

<routeDistribution id="!7107" state="0" routes="!7107#0 !7107#1 !7107#2" probabilities="1.33 1.33 1.34"/>

The vehicle with id "7107" is an already arrived vehicle. The vehicle in the route file is depicted as follows:
  <vehicle depart="0.75" departLane="random" departSpeed="avg" fromTaz="in_18" id="7107" toTaz="left8" type="warm_up_car">
    <routeDistribution>
      <route cost="99.35" edges="D6D7 D7C7 C7B7 B7B8 B8A8 A8left8" probability="1.33352733"/>                (!7107#0)
      <route cost="99.80" edges="D6D7 D7C7 C7C8 C8B8 B8A8 A8left8" probability="1.32770984"/>                (!7107#1)
      <route cost="98.97" edges="D6D7 D7C7 C7B7 B7A7 A7A8 A8left8" probability="1.33876284"/>                 (!7107#2)
    </routeDistribution>

The vehicle during the simulation used the route  edges="D6D7 D7C7 C7B7 B7A7 A7A8 A8left8" which corresponds to !7107#2 which is the missing route id from the state xml file. The only ones written are:

    <route id="!7107#0" state="0" edges="D6D7 D7C7 C7B7 B7B8 B8A8 A8left8"/>
    <route id="!7107#1" state="0" edges="D6D7 D7C7 C7C8 C8B8 B8A8 A8left8"/>

Best regards,
Manos

Please open up a ticket at https://github.com/eclipse/sumo/issues/new and attach minimal input files for replicating your problem (please try to pare down your scenario to the bare minimum).

Hi all,

I want to run my simulation up to a point (e.g. 2700s) and then save this state (using traci.simulation.saveState()). It seems that the function does not work properly. For example, when I am trying to load the saved state I get the following error message:
Error: Unknown route '!#_1532#0' in distribution '!#_1532'. (this happens many times inside the saved state xml)
The paths are generated using SUE (max alternatives = 5), teleport is deactivated and during the run, until the point I run my simulation in order to save it, I get no error whatsoever from traci.

Best regards,
Manos
