Exception when running useScheduleBasedTransport = false

[MayuriAnn]

Hi,

We attempted to execute our scenario with the parameter useScheduleBasedTransport = false in order to compare simulated bus travel times with scheduled travel times. However, we encountered the following exception:

RuntimeException: So far, this analysis tool only works with schedule-based simulation. Your simulation input simulated public transport in the QSim.
This exception was triggered by the class PublicTransportTripListener located at core/src/main/java/org/eqasim/core/analysis/pt/PublicTransportTripListener.java.

As a temporary workaround, we commented out the PT-related analysis components in the following files:

• core/src/main/java/org/eqasim/core/simulation/analysis/EqasimAnalysisModule.java
• core/src/main/java/org/eqasim/core/simulation/analysis/AnalysisOutputListener.java.

Would you recommend a better or more appropriate way to prevent this exception when not using schedule-based public transport?

Thank you in advance for your assistance.

Hi, I think @balacmi had the same issue and did some hack. Maybe I'll look into making this compatible, this would be even better.

[balacmi]

Yes, it's not a nice hack and only a temporary solution. Ideally, one would want to use SBB contrib, which allows one to select which PT modes should be schedule-based and which one simulated. This is what we do now in the swiss model.

@sebhoerl is there any reason to continue to use the eqasims schedule based pt instead of the one from the SBB contrib?

[sebhoerl]

No, not really, I think. Do you have an overview of what one has to configure?

[balacmi]

It is very lean, you need to add two modules, like here:

eqasim-java/switzerland/src/main/java/org/eqasim/switzerland/ch/RunSimulation.java

Line 48 in 5f63000

controller.addOverridingModule(new SBBTransitModule());

and one config group, where one selects which modes should be deterministc (e.g., schedule-based), everything else gets to be simulated:

<module name="SBBPt" >
  <param name="deterministicServiceModes" value="train,metro" />
  <param name="createLinkEventsInterval" value="10" />
</module>
