Hi Mohsen, I had a similar problem, where I needed a time varying demand in SUMO. My solution was to model the traffic flow distribution as a step function. The details of the step function that I defined are available in a paper that I have published (link below): https://dl.dropboxusercontent.com/u/1535439/ALA2015/papers/ala15_mannion_learning.pdf
I hope this will be useful to you.
