Abstract:
To research each feedback relation between traffic supply and demand, this paper reveals the dynamic relationship of them. Based on qualitative mechanism analyzing of interaction relationship between traffic supply and demand, the differential equation group for dynamic process of each feedback was established utilizing system dynamics theory, and the steady equilibrium solution was also obtained, the balance conditions of traffic supply and demand were put forward. The results indicate that, traffic supply and demand are interdependent and they promote each other, through the process of feedback loop, they can realize stable equilibrium under certain conditions, it satisfies the requirement of coordinate development when the mutual accelerating roles between traffic supply and demand are less than 1. 2 tabs, 5 figs, 9 refs.
