Re: [sumo-user] using network in od2trips

[Mirko Barthauer <m.barthauer@xxxxxxxxxxx>]

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).

 

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
