【摘要】：近年来,随着经济社会的快速发展,各地中心商业区(CBD)迅速崛起。中心商业区作为一个城市综合实力的体现或地标性建筑群,往往是一个地区最受瞩目的地方。中心商业区大多设在城市的各个重点核心地带,区内有相当完善的设施,但同时,中心商业区也是一个城市交通最拥堵的地方,对于现有的中心商业区,需要合理改善交通组织,对于拟建的城市新商业区,则更需要合理的规划内部交通基础设施。论文首先对交通承载力的相关理论进行研究,在阐述交通承载力的概念、特性以及影响因素之后,对交通承载力的主要计算方法进行总结分析,然后在此基础上,通过分析中心商业区的交通特性对中心商业区交通承载力进行建模;并在后续章节中在商业区的交通承载力模型基础上,分别建立适用于现有或拟建的城市中心商业区交通承载力时间预警和空间预警模型,对城市中心商业区进行交通时空预警。最后以交通承载力饱和度为指标,运用属性测度函数对大城市中心商业区交通承载力进行预警评价研究,并以珠海市“城市之心”CBD工程为例进行验证,得到2020年珠海市“城市之心”CBD工程交通承载力饱和度处于预警等级的第Ⅲ等级“中警”。通过以上研究,论文得到了适用于大城市中心商业区的交通承载力模型,并以此为基础分别建立中心商业区时间与空间预警模型,最后基于属性数学理论建立了交通承载力预警评价模型。但是论文中各模型所涉及的参数较多且部分取值采用经验值,文章中多数案例都以珠海为例,有一定的局限性。因此,在今后的研究中,将以此研究为基点,进一步对大城市中心商业区的交通承载力与承载力预警等方面进行深入研究。
[Abstract]:In recent years, with the rapid development of economy and society, CBD (Central Business District) has risen rapidly.As the embodiment of the comprehensive strength of a city or a landmark architectural complex, the central commercial district is often the most attractive place in a region.Most of the central commercial districts are located in the key core areas of the city, and there are quite good facilities in the areas. But at the same time, the central commercial districts are also the most congested places in the city. For the existing central commercial districts,It is necessary to improve the traffic organization reasonably, and to plan the internal transportation infrastructure for the proposed new commercial district.In this paper, the related theories of traffic carrying capacity are studied firstly, and then the main calculation methods of traffic carrying capacity are summarized and analyzed after explaining the concept, characteristics and influencing factors of traffic carrying capacity, and then on this basis,The traffic carrying capacity of the central commercial district is modeled by analyzing the traffic characteristics of the central commercial district, and based on the traffic carrying capacity model of the commercial district in the following chapters,The time and space early warning models of traffic carrying capacity of urban central commercial district were established, respectively, and the traffic space-time early warning model of urban central commercial district was established.Finally, taking the saturation of traffic carrying capacity as the index, the paper uses attribute measure function to study the early warning evaluation of traffic carrying capacity in the central commercial district of big city, and verifies the CBD project of "heart of the city" in Zhuhai City as an example.It is obtained that the saturation of traffic carrying capacity of CBD project in Zhuhai City in 2020 is in the third grade of early warning grade "middle police".Through the above research, the paper obtains the traffic carrying capacity model which is suitable for the big city central business district, and establishes the time and space early warning model of the central commercial district respectively.Finally, an early warning evaluation model of traffic carrying capacity is established based on attribute mathematics theory.However, there are many parameters involved in each model and some of the empirical values are used. Most of the cases in this paper take Zhuhai as an example, which has some limitations.Therefore, in the future research, we will further study the traffic carrying capacity and the early warning of the traffic carrying capacity of the central commercial district of the big city based on this research.
