Hi Jakob,

I tried to load the trips generated by od2trips directly into SUMO but still 
the routes are similar. I also tried to use Duaiterate with below configuration 
but while validating the output (edgestatedump) with our validation count data, 
the correlation results are not good. It is coming in between 0.2-0.3.

Configuration of duaiterate -

"C:\Users\Bhushan\sumo-msvc12x64-git\sumo-git\tools\assign\duaIterate.py" -n 
"C:\Users\Bhushan\Sumo\2018-06-05-21-00-00\map.net.edited1.xml" -b 109800 -e 
118800 -t 
"C:\Users\Bhushan\Sumo\2018-06-05-21-00-00\Trips\map.trip_June2_AM_scale_0.1.xml"
 -l 40 --convergence-iterations "5" --max-convergence-deviation "0.5" 
--pessimism "1".


Please let me know if any more parameters needs to be provided in duaiterate.


Also, let me restate my problem statement and it will be helpful if you could 
provide your insights-

As an input, I am taking a network from OSM along with polygon shape files and 
OD matrix which I am providing to generate trips. We want to run a simulation 
which is close to real world to compare it with the real world count data on 
different edges for the same network. As always I appreciate your suggestions 
and feedback.


Thanks,

When not given any other information, DUAROUTER picks the fastest route under 
the assumption that the network is empty.
To get better routes you need to perform user assignment.
A quick fix you can try is to load the trips generated by od2trips direclty 
into SUMO. This way, vehicles will react to traffic conditions at the time of 
insertion and the routes will be more realistic.
A more elaborate way is explained here:

Hello SUMO authors,


I have a network and creating trips using OD2trips. It picks an edge ID from a 
TAZ but OD2trips is generating the vehicles which are mostly on internal roads, 
they are not generating  from highways/freeways which should be the case in the 
real world.

Is there a way that I could assign trips so that the vehicles should generate 
from highways?


I also tried generating routes using DUAROUTER , but still it is taking the 
same internal routes.  In order to generate a scenario close to real world, 
please let me know a way using which we can enforce vehicles to follow 
highways/freeways rather than internal ways(roads containing traffic signals). 
Your help is highly appreciated.


Thanks,
