　　【Abstract】China is in a critical period of economic and social transformation, and the external ecological environment on which the urban transportation system depends for development has undergone significant changes. By the analysis of the internal and external dynamics of urban transportation system evolution and specific cases of urban transportation, this paper summarizes the system properties of the urban transportation system, including openness, complexity, and nonlinearity, as well as the characteristics such as the far-from-equilibrium state, internal interaction and balance, and self-organization. The paper proposes that the strategic orientation of urban transportation in the new era should change from pursuing the balance of supply and demand to adapting to the continuous evolution of the urban functional system. In addition, the goal orientation and planning-thinking method of the urban transportation system should be adjusted. Finally, this paper analyzes the major issues such as the capacity and intelligence of the urban transportation system and put forward suggestions.
