Hi Meng,
such problems grow with network size and are not easy to fix automatically.
Do you add public transport from schedules with fixed routes? Then you
could use the --vclass option in edgesInDistricts.py and exclude edges
limited to public transport.
Best regards

Betreff: [sumo-user] od2trips erros and TAZ definition in a large network

Hi SUMO expert,
I am using od2trips and tazRelation file to obtain route file , but there
are many warnings and errors like below when I execute trip2route:
Error: Mandatory edge '681882530' not reachable by vehicle '64140'.
Error: The vehicle '64140' has no valid route.
Error: No connection between edge '28109408' and edge '86113233#2' found.
I found two reasons: 1) trips of cars are generated on bus lanes (disallow
cars); 2) vehicles generate on destination edge ( only can exit the
network), so they cannot find connection between the destination edge and
other edges. As my network is big and TAZ file is obtained by
edgesInDistricts.py, I cannot specify source and sink edge manually for
each TAZ.
Therefore, how can I fix the above two problems? Is there any method to
constrain od2trips not assigning cars on bus lane, and any method to
specify source and sink edge in a large network? And there may be many
other problems I didn't find either. Could you give me any suggestions?
As the attachment size limit, I only attached my original files for your
reference. You can run the command following "using commands.txt".
Many thanks,
Meng
