[sumo-user] Combining Flows and Trips in DUAROUTER...

[Joe B.]

Hey, all -
I'm pretty new to SUMO, so please be patient. I have a question about
whether it's possible to have multiple randomized flows (using
vTypeDistributions) and user-defined trips both included in a scenario.
Typically, I get the following output when I attempt this:
<OUTPUT>
Error: The vehicle type 'bus' occurs at least twice.
Error: The vehicle type 'car' occurs at least twice.
Error: The vehicle type 'truck' occurs at least twice.
Error: The vehicle type 'van' occurs at least twice.
Error: Vehicle type distribution '-46673644-20130797#20_dist' is empty.
Error: The vehicle type '-46673644-20130797#20_dist' for flow
'-46673644-20130797#20' is not known.
Quitting (on error).
</OUTPUT>
and get no routes file at the end. Flows alone seems to work OK, as well
as trips (both random and user-defined together); the issue occurs when I
combine them. My input files look like this:

I have not used trips (yet), but I do use multiple flow files and a separate catalog for vehicle type definitions. I think I would take the hints in the first error messages and prune out the repeated definitions of the vehicle types; leave them in the first file you provide to duarouter, or separate them out into another “additional file” per SUMO definition of that file type. The latter choice should give you more flexibility in the future to vary vehicle performance parameters.

I’m not sure about the last error messages about the vehicle type distributions but perhaps those will go away when you get your vehicle types defined once and accepted as input to duarouter.

Also, if you do not want to search them manually, duarouter has the
option --vtype-output to write them to a separate file.
