  Pursuing three important elements including economic, safety, and traffic are
the overall objective of decision evaluation across all transport projects. In
this study, we investigate the feasibility of the development of city
interchanges and road connections for network users. To achieve this goal, a
series of minor goals are required to be met in advance including determining
benefits, costs of implement-ing new highway interchanges, quantifying the
effective parameters, the increase in fuel consumption, the reduction in travel
time, and finally influence on travel speed. In this study, geometric
advancement of Hakim highway, and Yadegar-e-Emam Highway were investigated in
the Macro view from the cloverleaf inter-section with a low capacity to a
three-level directional intersection of the enhanced cloverleaf. For this
purpose, the simulation was done by EMME software of INRO Company. The results
of the method were evaluated by the objective of net present value (NPV), and
the benefit and cost of each one was stated precisely in different years. At
the end, some suggestion has been provided.
