Identifying the parameters affecting traffic flow density can be effective for decisions makers and policies for investment and prioritization of executive plans and projects. In this research, the effects of vehicle specifications on traffic density in the highway network of Tehran have been identified. For this purpose, information of Hemat highway has been collected and modeled. Geometric details and movement characteristics of cars can affect the quality of traffic flow. The present study is an objective research type and is survey research in terms of data collection. This issue is more crucial in highway and arterial crossings where other parameters such as delays and stops due to intersections and interferences are less. The method of research is quantitative and statistical models have been used to analyze the data. According to the results of the study, the length of vehicle, travel time, vehicle speed and volume of vehicles had the greatest impact on traffic density.
