Abstract

Abstract

According to the multiformity of traffic flow models and the measure value variety of the same parameter, this paper analysed the modeling principles and the consistent of measure and statistics methods. In the light of the physical magnificence of model parameters, applying the dimension analysis method, the paper studied several traffic flow models and their parameters, and deduced the basic results about the similarity of these models and the function formulas of their parameters. The dissipation procedure of traffic flow density wave was analyzed by dimensionless theory, and the analytic conclusion can explain the dimensional counterpart of high velocity and low velocity traffic flow models. The dimension analysis method has theoretical and practical value for further developing traffic flow theories.
