【摘要】：城市中心商业区作为城市经济活动集聚化的产物,是城市发展的精华、经济水平的体现,也是展示城市整体形象的主窗口,很大程度上带动了城市的繁荣、经济的发展。随着我国近几十年来改革开放所取得的巨大成效,各地城市相继将中心商业区建筑改造和建设列为城市发展的重点。由此在扩大的中心商业区城市容量的过程中,为原本有限的区域交通系统增添的了新的压力。交通组织优化方法作为改善局部交通拥堵问题的重要手段,有着便捷、高效、易于实施的特点,也是目前城市交通管理研究的重点。本文主要针对中心商业区特征及组织优化理论、商业区交通需求预测和路网组织优化方法等问题进行了研究。在商业区特征及组织优化理论方面,通过对其形成过程分析,对商业区的交通特征进行了探讨,总结了我国各城市中心商业区交通所普遍存在的问题及成因,并提出了商业区未来交通改善的重点和策略；在交通需求预测方面,结合中心商业区开发体量大的特点,以区域交通规划理论为基础,针对商业区地块开发做造成的交通需求快速增长等现象,引入区位势能条件,对变更后的交通需求进行预测,提高了区域交通需求预测精度,为之后的区域交通组织和规划提供了有效的数据基础；在路网组织优化方面,针对商业区新增建设项目后的交通分配结果,以区域路网饱和度限定为约束条件,建立区域道路网络组织优化模型,并给出模型的遗传算法求解方法,并结合湘潭市建设路口商圈的建设现状,以建设路口西北角地块开发湘潭国际商业中心项目建设为背景,提出局部交通组织优化方案。城市中心商业区作为展示城市社会经济水平的主窗口,是城市发展的核心。本文针对以中心商业区新增项目背景下的区域交通需求变化进行了研究,引入了区位势能思想进行需求预测,并对预测后的商业区道路单向与禁左交通组织方法进行了探索。结合本文所做研究,对中心商业区的交通组织优化方案制定有一定的借鉴意义。
[Abstract]:As a result of the agglomeration of urban economic activities, the central commercial district is the essence of urban development, the embodiment of economic level, and the main window of displaying the overall image of the city, which to a great extent leads to the prosperity and economic development of the city. With the great achievements of reform and opening up in recent decades in China, the reconstruction and construction of central commercial district has been listed as the key point of urban development in various cities. Thus, in the process of expanding the capacity of the central commercial district, it adds new pressure to the previously limited regional transportation system. As an important means to improve local traffic congestion, traffic organization optimization method has the characteristics of convenience, efficiency and easy to implement. It is also the focus of urban traffic management research. In this paper, the characteristics of the central business district and the theory of organization optimization, traffic demand forecasting and road network optimization methods are studied. In the aspect of business district characteristics and organization optimization theory, through the analysis of its forming process, the traffic characteristics of commercial district are discussed, and the problems and causes of traffic in central commercial district of our country are summarized. The paper also puts forward the key points and strategies of traffic improvement in the future. In the aspect of traffic demand prediction, combined with the characteristics of large volume of central commercial district development, based on the theory of regional traffic planning, and aiming at the phenomenon of rapid growth of traffic demand caused by the development of commercial district plots, the location potential energy condition is introduced. Forecasting the traffic demand after the change improves the precision of regional traffic demand prediction and provides an effective data base for the later regional traffic organization and planning. In the aspect of road network organization optimization, aiming at the traffic assignment result after the new construction project in the commercial district, taking the regional road network saturation as the constraint condition, the optimization model of the regional road network organization is established, and the genetic algorithm solution method of the model is given. Combined with the present situation of the construction of the commercial district at the intersection of Xiangtan city, the optimization scheme of local traffic organization is put forward in the background of the construction of Xiangtan international commercial center project in the northwestern corner of the intersection. As the main window to display the social and economic level of the city, the central commercial district is the core of the urban development. In this paper, the change of regional traffic demand under the background of the new project of central commercial district is studied, the idea of location potential energy is introduced to forecast the demand, and the method of organizing one-way and forbidden traffic in commercial district after prediction is explored. Combined with the research done in this paper, it has certain reference significance for the traffic organization optimization scheme of the central commercial district.
