Re: [sumo-user] Demand generation using OD matrix
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: http://sumo.dlr.de/wiki/Demand/Dynamic_User_Assignment

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,
