Abstract:

Urban transport is a complex system phenomenon of ‘society-technology-nature’. The coordinated development between urban transport and land use subsystem is the basis of reducing transport problems, one of the core theoretical problems of urban geography, and one of the key contents of urban and regional planning. Simulation and prediction of the interaction between urban transport and land use is a key point in scientific regulation of their relationship. However, there is a lack of discussions on key technologies of the integrated model of urban transport and land use. According to the microscopic location choice based on the theory of land rent and the macroscopic dynamic interaction theory of land use and transport system, the development process of the integrated models of urban transport and land use and the classification characteristics are reviewed. The tradeoff between travel cost and location decision is the basic micro mechanism for the formation of travel demand and its spatial distribution (origin and destination). Land use and traffic flow are the aggregate manifestation of individual micro location choice and travel behavior of enterprises and residents. There is a dynamic interaction process between land use and transport system. Land use affects travel demand and its layout, and then affects traffic flow. Transport facilities and traffic flow affect the accessibility and congestion of the region, thus affecting location choice and urban land use. The advantages and disadvantages of spatial interaction and gravity model, spatial economics model, stochastic utility and discrete selection model and behavior based micro model are systematically analyzed. The analysis shows that the research of the integrated model with reasonable theoretical basis, scientific data processing, high model accuracy and certain applicability of policy evaluation still has a large development space. In recent years, the research of western scholars on the integrated model tends to be micro, integrated and simplified. In western countries, integrated models of urban transport and land use are often developed for urban reality analysis and policy evaluation, while domestic researches mainly focus on the interaction and coordination analysis between transport system and land use. The development of domestic integration model is relatively lagging behind, which requires the further breakthrough of model theory and comprehensive empirical development. Especially in the context of new data, new transport technology and territorial space planning system, the integrated model of urban transport and land use will change from ‘spatial’ model to ‘time-space’ model, from ‘macroscopic’ aggregate model to ‘microscopic’ behavior model, from ‘transport-land use’ model to ‘integrated system’ model, from “sample data” model to ‘big data’ model, from the application of ‘transport planning’ to the application of ‘territorial space planning’. In order to promote the research and development of the integrated model in China, this paper analyzes the general structure, principle types, current problems and challenges of the integrated model of urban transport and land use. It has certain theoretical significance and practical value for quantitatively exploring the interaction between urban transport and land use and developing the integrated model of urban transport and land use in China.
