Re: [sumo-user] help with simulation from turn-counts

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

jtcrouter doesn't do a systematic search for routes that end on the outer boundary of the network. It can match the exact turn counts when setting options --discount-sources and --sources-are-sinks but sine routes will likely end in the middle of the network. If routes start on inner edges despite option --fringe-flows this may be a bug and I invite you to provide a minimum working example to reproduce this.

To achieve full control over the routes, I recommend the use of routeSampler. First define the set of routes that you wish to allow and then use the same edgeRelations you already defined for jtcrouter.

See https://sumo.dlr.de/docs/Tools/Turns.html#routesamplerpy

I'm trying to create a test for a study I'm doing.

I have turn-counts from 11 intersections and wanted to create routes from the ends of the network (intersections highlighted in the figure).

I created the file with the turn count data and used the jtcrouter.py algorithm (with --fringe-flows) but it still has trips starting from the inner edges.

How do I create routes from observation points that start and end at the ends of the network?

Will this algorithm make the simulation turn-counts the same as the counted ones?

Thank you in advance
