Mixed traffic is a remarkable character in our country, and therefore, a study on traffic composition is always one of the critical issues in the national traffic engineering field. In this paper, a concept of a large vehicle is used on a basic freeway section, investigated the real-time traffic flow to acquire parameters of vehicle type model. With the help of simulation software, we carried a study on how the 3 traffic flow parameters namely, density, speed and volume, change with the different large vehicle mix rates to find out the sensitivity analysis of large vehicle mix rate to traffic flow state parameters. Finally, we were able to determine the most unsafe large vehicle mix rate in a basic freeway section. The results from this paper are considered as a technical support to speed limits on freeway and traffic management decision system.
