Fast urban mechanization on the one hand facilitates the urban development, and on the other hand, brings along a series of traffic problems. This paper takes Beijing as the background to analyze the mechanization trend of the urban transportation and indicate that car traffic is the main force driving the course of urban mechanization, as well as calculate the relationship between urban motor vehicle ownership and GDP. On the basis of taking into account the factors including socio-economy, traffic demand, traffic supply, traffic operation condition, transport policies, etc. in a systematical way, this paper analyzes the causal relationship among these factors and builds a System Dynamics (SD) model for adjustment of urban transportation structure. Based on this, it makes the simulation analysis on the urban transportation condition under different travel characteristics and the corresponding mechanized transportation structure, and considers it especially important to change the travel behavior characteristics of residents for improving the urban transportation condition, which provides the instrumentality of quantitative analysis for the optimization of urban transportation structure.
