Today, in Third-world countries such as Iran tendency the population growth and width of transportation and high rank of needed increase the number of cars and travels, that thi is increasing of the unreasonable of travel time and high rate of accidents. So the expection the density of passing traffic for a street and capacity analysis to extence and improvement of road network is too important. In this essay, we inspect truly the passing traffic of highway between Semnan-Garmsar simulating CORSIM software. Then with changeable geometric matters we analyse the changes of the density of passing traffic and the race of passing traffic. This highway is one of the important roadway in our country for transferring passengers and stuffs and is apart of road connectivity between west-east. CORSIM is a through going simulated software in science traffic engineering, which has the high capability in analysis of road network. As a result of lacking acquaince with this software, its used is limited in our country and until now it is uselessness about urban highway network. Geometritic and traffic information was received through real observation so that they have great accuracy.
