Studies On Integrated Model For Urban Land Use And Transportation Based On Bid-rent Theory

Urbanization and motorization is closely related to the social and economic developmentlevel. It is not only lead to the sustained and rapid growth of urban population and trafficdemand directly, but also brought some negative effect, such as excessive populationagglomeration, worsening traffic congestion, aggravating environmental pollution, socialinequality, and so on. Nowadays, the common problems and great challenges faced by theurban planning and traffic administrative department mainly includes: how to maintain arelatively high level of social and economic efficiency and control the growth of populationand travel demand simultaneously，by making effective development policy of real estate andtransportation? How to prevent or alleviate the urban traffic congestion via coordinating therelationship between travel demand and the traffic network capacity? From the perspective ofurban land use and transportation integration development, understanding the interactionmechanism between the "source" of traffic demand (land use) and the "flow" of traffic supply(traffic network), proposing an optimization model framework of land use and transportationsystem, and analyzing and evaluating the impact of different land use policy and trafficdevelopment strategy on system performance comprehensively, are the key to solve the aboveproblems.In the thesis, the decision-making behavior of different participants and their interactionsin urban land use and transportation system are firstly modeled, and an open, extensiblequasi-dynamic model framework is also proposed. A combined equilibrium integrated modelof urban land use and transportation is then developed to model residents’ location and travelchoices, as well as real estate developers’ housing supply decisions, based on the modelframework and bid-rent theory. The existence and uniqueness of solution of the combinedequilibrium model are verified through two equivalent mathematical programming models,and the model parameter estimation method and solution algorithm are also presented. Basedon the combined equilibrium model, the optimal integrated development strategies of land useand transportation are discussed and analyzed. A system optimization model is proposedbased on transport supply and demand management (TS-DM) strategies; the impacts andoptimization of TS-DM strategy on the performance of the system are studies as well. Mathematical analyzed results show that the improvements of transportation lead to thereduction of travel cost and an equal increase of the rent (housing prices), and benefit realestate developers rather than inhabitants under the scenario of homogeneous value of traveltime and residential utility. In addition, transport improvements benefit people with a higherincome more under the scenario of heterogeneous value of travel time，as well as theimprovements of transportation lead to the reduction of travel cost and an equal increase ofthe rent (housing prices). These results suggested that the improvements of traffic facilitiesmay bring negative effects, which is consist with the numerical example analysis results.TS-DM strategy has a positive effect on the optimization of traffic congestion, residentiallocation, travel choice, land use patterns etc. It is helpful for city managers to grasp the effectof various policies or strategies and make the optimal TS-DM strategy in the furtherdevelopment of land use and transportation. Furthermore, TS-DM strategy contributes topromoting the virtuous cycle of urban land use and transportation, and preventing andrelieving traffic congestion effectively, as well as promoting the urban sustainabledevelopment, which has important theoretical significance and application value. However,the TS-DM strategy makes the consumer surplus experience a process of loss, the essence ofwhich is likely to damage the interests of some social groups， and has a negative impact onthe society.
