_______________________________________________I am wondering what exactly is wrong with my flow_example.rou.xml file. Do I need to impart routes within the flows in the flow_example.rou.xml file? If so, I thought the whole point of jtrrouter was to develop a routes or a rou.xml file.

Okay, I am just making sure because I tried replacing the –flow-files with –route-files and expanding the flow definitions in the route-file and I got this error message:
My route-file looks something like this:
I am trying to get multiple flows to enter the network at the same time. I tried following this documentation guidance (https://sumo.dlr.de/docs/Demand/Routing_by_Turn_Probabilities.html) since I didn’t know what my destination would be for the vehicles flowing into the network:

You do not need sinks. In this case all your may be either end "naturally" by running into a dead-end (i.e. network border) or end after using at most 2 times the total number of edges in the network.
Regarding the outdated option. Just write --route-files instead of --flow-files.

I also forgot to ask, what is the appropriate way to use the jtrrouter since the flow-files is outdated?

Thanks for the response. I am still a little confused by what you are saying.
I understand what you are saying about the sink definitions. However, do I need to have sink definitions added to my turn files to generate a route file? I just went back to my computer and I noticed that a route file was generated any way from what I had shown you previously.
Also, for the warning about the “flow-files”, since it is outdated what should be used in its place instead? Is there an alternative to this?
Thank you

Hello,
- the warning about "flow-files" only concerns the option name (the documentation page contained and outdated option name)
- the warning about unclosed routes is caused by the lack of sink-definitions. See https://sumo.dlr.de/docs/Demand/Routing_by_Turn_Probabilities.html#sinks_definitions

Jakob

Hello Everyone
I am working with turn probabilities in order to produce routes within my network and I am currently trying to test and see if a flow of vehicles can enter and move through the following intersection successfully. Please know that this is one in a chain of intersections and I am just trying to get the hang of working with jtrrouter by working on this one intersection for now.
I was able to create flow definitions, a turn ratio file, and network file to generate a routing file for my vehicle in the flow file. Please the files below:
Flow definition file:
Here I followed the instructions for flow definition when the destination is not known within a vehicle’s route.
Turn-Ratio File:
…and of course the net-file is extremely large because it was generated from the OSMWizard.
Once aggregated and placed as inputs into jtrrouter to produce a rou.xml file, I got this error message and I am not really sure what is going on. I am not really sure what ‘flow-files’ is deprecated means. Do I need to put turn probabilities for all intersections in my network? Also what does “The route starting at edge ‘OldShellEB1’ could not be closed” means and how can I fix this problem?
Thank you in advance for the assistance
Ifezue
