Perusing three important elements ( economic, safety and traffic) is the overall objective of decision evaluation across all transport projects. In this study, we investigate the feasibility of  development of city interchanges , and road connections for network users. In order to achieve this goal, a series of smaller goals are required  including determining benefits, costs of implementing new highway interchanges, quantifying the effective parameters, quantifying the increase in fuel consumption, quantifying the reduction in travel time and growth in travel speeds . In this study, geometric advancement of Hakim highway, and Yadegar-e-Emam highway was investigated just Macro from cloverleaf intersection with a low capacity to  three-level directional intersection and enhanced cloverleaf. For this purpose, the simulation was done by EMME /2 software . The results of the method  of net present value (NPV) were evaluated economically , and the benefit and cost of each one was stated precisely in different years (\%28 improvement). The sensitivity analysis indicated that the cost of fuel, cost of travel time, cost of accidents and cost of pollutants have the highest impact factor in this assessment respectively .
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 .
