Hi all,

I am trying to create a mixed traffic scenario and have followed the instructions at this page:

https://matsim.atlassian.net/wiki/display/MATPUB/Mixed+traffic

I am using my own scenario run, but it is essentially the same except it uses car,truck instead of car,bicycle. Note my example also has a few other things going on including transit and subpopulations.

I have checked my inputs against the equil-mixedTraffic example inputs, and mine appear to be the same. Note, I have also needed to add the travel time and disutility bindings in Java crossed out at the bottom of the above-linked tutorial (I am working in MATSim v0.8.1).

I am getting the following error:

"Expecting a vehicle id which is missing in the vehicles database: 0"

or, if I set "usePersonIdForMissingVehicleId" in the qsim module to false (as suggested in Section 11.1 of the MATSim book, but not in the above-linked tutorial or the equil example config file), I get this error:

"Found a network route without a vehicle id."

Any assistance would be greatly appreciated. Thanks in advance.

Renan.

    Dear Renan,

    Thanks for reporting this.

    The steps on the page Mixed traffic are meant for the releases after 0.8.1 (This is informed on the Mixed traffic page now). 

    For v0.8.1, the following error: "Expecting a vehicle id which is missing in the vehicles database: 0" indicates that the vehicle ids are missing from the vehicles file. Please create a vehicle (of vehicle type car/truck/bicycle) for every person and add to the vehicles file and use "fromVehiclesData" vehicle source in QSimConfigGroup. In addition to this, travel time and dis-utility bindings are also required (as you are already doing this). 

    Let me know if this works for you.

    Regards,

    Amit
