Therefore, based on the research of pathology, aiming at the long-term dissevered between the land use and transportation network system in the urban planning, construction and management fields, and the narrow definition of urban transportation system and matching supply and demand of this contradictions unity, this thesis define the integrated urban land use-transportation system (abbreviation IULTS, urban L-T system or system for short). From the interaction and the spontaneous mutual adjustment phenomena between the land use subsystem and transportation subsystem, this thesis explore the inherent laws and internal mechanism of IULTS evolution behind the phenomena, and proposed system optimization theory and methods from the mechanism of system development and evolution. It is expected that the conclusion can provide a meaningful reference for analyzing and solving traffic problems, and understanding deeply the matter that if IULTS is controllable, how to control and the direction, theory and methods of controlling.
