Study On Synergic Development Between Urban Land Use And Transportation System

In recent years, with the rapid progress of urbanization and the rising levels of motorization, the urban traffic problem has been increasingly severe, becoming one of the most important issues hindering the sustainable development of cities. The improvement of the problem relies essentially on the coordination between the urban land use and the traffic system. Therefore, it is of great necessity to study the internal relations between the land use and the traffic system, to show their internal disciplines, and to seek for the ideal approach to achieving the coordinated development. The research has great significance for solving the urban traffic problem and promoting the cities' healthy, sustainable development.Based on the traffic generated "source"-the land use and the traffic supply "flow"-the traffic system, this paper employs a technical route combined with theoretical and empirical analysis. Through the correct understanding of the interactive relations, this thesis aims to discover the theoretical method to achieve the coordinated development of the urban land use and the traffic system, and it conducts the research from the following aspects:Firstly, it studies the interaction mechanism of the land use and the traffic system. Secondly, from the perspective of empirical research, it selects Dalian as the research object and studies the impact of the land use on the traffic system and the impact in reverse. In terms of the former impact analysis, it selects the land-use characteristics in the urbanization progress as the starting point, chooses the Dalian Port as the research object, and studies the changes of land use patterns and the resulting traffic demands after the overall relocation of Dalian Old Port. In terms of the analysis on the impact of the traffic system on the land use, it mainly starts from the effect of rail transit on the land value. It adopts the asset value method to quantitatively calculate the effect, and to study the mechanism which the traffic system influences the land use. Finally, based on the theoretical and empirical analysis of the interaction mechanism, it points out that the Transit Oriented Development is the optimal method to achieve the coordinated development. In order to study the effect of TOD method on the improvement of traffic conditions, it collects the basic data of Dalian rail transit and the residents' trips, builds the traffic demand forecasting model and the effect evaluation method, and calculates the overall effects of this method.The result demonstrates that the TOD program based on the rail transit are able to induce the rationalization of the urban land use, due to its obvious effects on the improvement of traffic problems.
