【摘要】：历史街区是城市历史文化沿革变迁的实物见证,应对其加以保护,随着城市交通需求的增加,历史街区所承受的交通压力也与日俱增。为了缓和交通需求和历史街区保护之间的矛盾,使历史街区道路在满足历史街区保护要求的前提下,通过合理的交通组织管理方法,满足街区日增的交通需求,可利用历史街区内密布的街巷网络组织交通微循环。本文首先以系统论的视角,从系统要素、系统结构及系统功能三个方面论述了交通微循环系统的概念。基于此,结合历史街区的特点,探讨了历史街区交通微循环系统,通过对历史街区交通需求与交通供给矛盾的分析,论述了历史街区交通微循环的必要性与可行性,提出了历史街区交通微循环的实施目标。其次,历史街区交通微循环系统的物质载体是街区内部道路,然而街区内部道路现状通行条件普遍较差,需对其合理规划,从而保证交通微循环的顺利实施。本文结合对历史街区道路交通的调查分析,总结历史街区道路的使用功能,对历史街区道路划分了三个等级,并对历史街区道路横断面和车行速度进行了分级规划,为历史街区交通微循环奠定了基础。基于历史街区道路分级规划,论文建立了以保障干路网络的畅通性,减小绕行距离、缩短绕行时间和控制环境污染为优化目标、以街区内道路通畅和保护历史遗存为约束条件的单向交通组织优化模型,并给出了借用交通规划软件Trans CAD的模型求解步骤。作为综合交通体系,历史街区交通微循环系统不应仅考虑机动车交通组织,本文还从慢行交通改善、公交线路规划、停车设施规划、市政管线改造以及历史街区风貌维护五个方面对历史街区实施交通微循环系统提出了规划与改善措施。最后给出了历史街区交通微循环系统组织流程,为历史街区交通运输组织提供参考。最后,本文以开封市的草市街历史街区为实例,对研究成果的有效性和可行性进行了验证。本研究得到《中西部历史名城历史街区空间保护与再造的交通运输规划设计理论与方法研究》国家自然科学基金(NO.51278396)的资助。
[Abstract]:The historical district is the physical witness of the evolution of urban history and culture. It should be protected. With the increase of urban traffic demand, the traffic pressure on the historical district is increasing day by day. In order to ease the contradiction between traffic demand and historic block protection, make the road of historical block meet the requirement of historic block protection, and meet the increasing traffic demand through reasonable traffic organization and management method. The traffic microcirculation can be organized by using the dense network of streets and alleys in historical blocks. In this paper, the concept of traffic microcirculation system is discussed from three aspects: system elements, system structure and system function from the perspective of system theory. Based on the analysis of the contradiction between traffic demand and traffic supply, the paper discusses the necessity and feasibility of traffic microcirculation in historical district. The implementation goal of traffic microcirculation in historical district is put forward. Secondly, the material carrier of the traffic microcirculation system in the historical district is the road inside the block. However, the current situation of the road in the block is generally poor, so it needs to be reasonably planned to ensure the smooth implementation of the traffic microcirculation. Based on the investigation and analysis of the road traffic in the historical block, this paper summarizes the use function of the road in the historical block, divides the road in the historical block into three grades, and makes a hierarchical plan for the cross-section of the road and the speed of the vehicle in the historical block. It lays the foundation for the traffic microcirculation in the historical district. Based on the hierarchical planning of the road in the historical district, this paper has established the optimization goals of ensuring the smooth running of the trunk road network, reducing the detour distance, shortening the detour time and controlling the environmental pollution. This paper presents a one-way traffic organization optimization model based on the constraints of unobstructed roads and the preservation of historical relics in a block. The steps of solving the model by using Trans CAD are given. As a comprehensive traffic system, the traffic microcirculation system of historic blocks should not only consider the traffic organization of motor vehicles, but also from slow traffic improvement, bus route planning, parking facilities planning. The planning and improvement measures of the traffic microcirculation system in the historic district are put forward in five aspects: the reconstruction of municipal pipelines and the maintenance of historical district features. Finally, the organization flow of the traffic microcirculation system in the historical district is given, which provides a reference for the traffic and transportation organization in the historical district. Finally, this paper takes the historical district of Caoshi Street in Kaifeng City as an example to verify the validity and feasibility of the research results.
