I believe there are no studies on this, but I believe that on unpaved roads congestion is higher

thanks a lot Mr. Giofre, I've seen some studies in this subject, but they aren't exactly what i'm going to do.  

Dear Ahmad, 

I do not know of any published studies on the effect of land use on traffic congestion. 

However: 

May I suggest that your problem has four major components. 

Firstly, you have to determine tha traffic which will be generated by your proposed land use.  Broken down, naturally, into incoming and outgoing traffic - origins and destinations. 

Secondly, you have to consider the various road links, and determint the capacity of each in incoming and in outgoing directions, making due allowance for existing traffic of course.  (I am assuming no rail link, just to simplify matters.) 

Thirdly, you would allocate incoming and outgoing road traffic to the various relevant road links. 

And finally, the comparison of second and third results should enable you to determine the degree of traffic congestion your particular land use will cause on each link, in each direction. 

I hope these few comments may prove  helpful to you. 

Sterkte!   Graham. 

Dear Ahmad,

I have published an article related on the effect of land use in public transportation planning in consideration of congestion in the journal of Promet Traffic and Transportation. I do not know whether the subject of the paper is exactly related to your question but it could be helpful to you. I'm sending you the link of the paper below.

I don't know exactly what you are looking for, as a lot has been published on the relation between land-use and transport. Maybe you could start with a paper such as:

Marlon Boarnet, Randall Crane, The influence of land use on travel behavior: specification and estimation strategies, Transportation Research Part A: Policy and Practice, Volume 35, Issue 9, November 2001, Pages 823-845, ISSN 0965-8564, http://dx.doi.org/10.1016/S0965-8564(00)00019-7.

Tnx Mr. Baskan

Tnx for the article Mr.Jou

I found in many research papers, nowadays, Simulation of Urban MObility (SUMO) becomes popular for traffic congestion & flow
