Hi Soheil,
this is the general problem with trips: You do not know exactly which route
will/can be taken to reach the destination as a trip merely knowns its OD
pair. There is no way to consider this directly in od2trips. Normally
however you should still get a message when running the simulation saying
some vehicle could not be inserted because of an unfeasible route or
similar. You can choose to ignore such vehicles calling sumo with
--ignore-route-errors true (see docs
<https://sumo.dlr.de/docs/Demand/Automatic_Routing.html#incomplete_trips_and_flows>
).
Otherwise you would need to work on the TAZ definition and/or the road
network to avoid cases where there is no connection between origin and
destination.
Best regards
Mirko

Hi all,
I have been recently trying to generate my demand route file using
od2trips. Below is the code I use to generate demand:
od2trips -n {taz_add_file} -d {od_files} -o {output_directory} --vtype
passenger --different-source-sink true --departlane free --departspeed
max
However, when I run the simulation it stops after a while and does not
throw an error log so I cannot explicitly know where the problem is. I
think the reason is that there are no viable routes from some origin
links/TAZs to destination links/TAZs.
That is why I was wondering if there are any ways to make od2trips consider
route availability between origin and destination. Something like forcing
to add net.xml file as one of the inputs.
Thanks in advance.
Regards,
Soheil
