Thank you very much. I would be happy if you could send me any document regarding how to change user equilibrium to system optimal algorithm. 

Regards,

Correct. There is currently no tool in SUMO that would find the system optimum for you directly.
However, you should be able to hook into the UE assignment iteration and swap out average travel times with your own estimate of marginal travel times to approach the SO as described in the literature.

Jakob

Dear Jakob, 

Thank you very much for your reply. I found only the User Equilibrium (UE) assignment, and there is no System Optimal (SO) Assignment, am I right?

Regards,

Hello,
all the algorithms of SUMO are open source. (https://github.com/eclipse/sumo)
The traffic assignment is chiefly done in a microscopic fashion (because SUMO is predominantly a microscopic simulation) but there also exists an application for macroscopic assignment. For details, see https://sumo.dlr.de/docs/Demand/Dynamic_User_Assignment.html

Jakob

Hello Dear All, 
I would be happy if you could answer the following questions: 

1. I want to run a macroscopic dynamic system optimal traffic assignment in which I can embed a criterion for the traffic assignment algorithm solution.  
Is it possible to do so in SUMO?

-is the traffic assignment algorithms' source code available in SUMO?

If so, How? 

Regards,
