【摘要】：地铁车站内乘客的活动路线称为流线,而流线的组织与设计合理与否,对提高整个车站的运营效率和服务水平至关重要。武汉地铁中南路站是2号线与4号线的换乘站,采用同台单向换乘模式,与洪山广场站结合实现双向快速换乘,其换乘效率的高低直接影响整个地铁的运行能力。随着武汉地铁4号线的开通,中南路站客流激增,高峰时段的换乘流线较为混乱,因此迫切需要分析流线混乱原因并合理地重新组织站内流线,以保障旅客换乘的安全和便捷。论文首先阐述地铁车站的空间及流线的基本概念,并分析讨论影响流线的诸因素及流线的量化评价标准。在此基础上,通过武汉地铁中南路站的现场调查和采集站内客流数据,查找当初的设计流线难以有效实施的主要原因,分析目前的现状流线存在的主要问题,从换乘流线的重新组织和站内工程设施改造二方面入手,提出2种换乘流线的重组方案,并利用legion软件分别对原设计流线、现状流线和2种重组流线进行仿真分析和量化评估。主要研究成果如下:(1)武汉地铁中南路站的换乘客流比例远高于出站客流比例,4号线建成后的换乘客流已成为站内主要客流,凸显了中南路站的换乘站属性。4号和2号线路在早晚高峰时段的换乘客流,并未出现客流潮汐现象,但由于晚高峰时段的进站客流量大,容易造成站内拥堵。(2)武汉地铁中南路站因不具备2条线路的双向同台快速换乘功能,致使本应该在洪山广场站换乘的部分乘客穿过站厅往对向站台换乘,是理想化的原设计流线难以有效实施的主要原因。进出站和换乘流线的交叉导致站厅产生拥堵并影响换乘效率,成为现状流线混乱的根源和瓶颈。(3)站内流线的legion仿真模拟可逼真描述客流密度、速度等影响换乘效率诸因素的时空分布,因而可实现不同流线方案的量化分析与优化评估。仿真分析显示:理想化的原设计流线较为顺畅,而现状流线则较为混乱。重新布设流线的重组方案虽可减少部分流线交叉,但难以根治换乘流线的混乱状况;改造站内工程设施的流线重组方案可有效消除流线交叉,从而可彻底解决中南路站换乘流线混乱问题,但需增加改造费用并克服施工困难。论文研究成果可为中南路站换乘流线的重组和站内设施改造提供科学指导,促进地铁车站换乘效率和服务水平的提高。
[Abstract]:The movement route of passengers in subway station is called streamline line, and the organization and design of streamline line is very important to improve the operation efficiency and service level of the whole station. Wuhan Metro Zhongnan Road Station is a transfer station between Line 2 and Line 4. Using the same station one-way transfer mode and combining with Hongshan Square Station to realize two-way rapid transfer, the transfer efficiency directly affects the operation capacity of the whole subway. With the opening of Wuhan Metro Line 4, the passenger flow of the Central South Road Station has increased sharply, and the transfer line in the peak period is more chaotic. Therefore, it is urgent to analyze the causes of the flow line chaos and reasonably reorganize the flow line in the station to ensure the safety and convenience of passenger transfer. In this paper, the basic concepts of space and streamline of subway station are introduced, and the factors affecting streamline and the quantitative evaluation standard of streamline are analyzed and discussed. On this basis, through the field investigation and collection of passenger flow data of Wuhan Metro Central South Road Station, the main reasons why the original design streamline is difficult to implement effectively are found, and the main problems existing in the current streamline are analyzed. Starting with the re-organization of the transfer streamline and the reconstruction of the engineering facilities in the station, two recombination schemes of the transfer streamline are put forward, and the simulation analysis and quantitative evaluation of the original designed streamline, the current streamline and the two recombined streamlines are carried out by using legion software. The main research results are as follows: (1) the proportion of transfer passenger flow at Wuhan Metro Central South Road Station is much higher than that at the outbound station, and the transfer passenger flow after the completion of Line 4 has become the main passenger flow in the station. The transfer station attribute of Zhongnan Road Station is highlighted. The transfer passenger flow of Line 4 and 2 in the morning and evening peak hours does not appear the tide phenomenon of passenger flow, but due to the large incoming passenger flow in the late peak time, It is easy to cause congestion in the station.) because Wuhan Metro Central and South Road Station does not have the two-way high-speed transfer function of two lines, some passengers who were supposed to transfer at Hongshan Square Station pass through the station hall to transfer to the opposite platform. Is the idealized original design streamline is difficult to effectively implement the main reason. The intersection of incoming and outgoing stations and transfer lines leads to congestion in the station hall and affects the transfer efficiency, which becomes the source and bottleneck of the current streamline confusion. The legion simulation of the streamline line in the station can describe the passenger flow density realistically. The time and space distribution of the factors such as speed and so on affect the transfer efficiency, so that the quantitative analysis and optimization evaluation of different streamline schemes can be realized. Simulation analysis shows that the idealized original design streamline is more smooth, while the current streamline is more chaotic. Although the reorganization scheme of rearranging streamline can reduce some of the crossover of streamline, it is difficult to eliminate the confusion of transfer line, and the recombination scheme of streamline in engineering facilities can effectively eliminate the crossover of streamline. So it can solve the confusion problem of the transfer line of the Central South Road Station, but it needs to increase the cost of reconstruction and overcome the construction difficulties. The research results of this paper can provide scientific guidance for the reconfiguration of transfer streamline and the transformation of facilities in the station, and promote the efficiency and service level of subway station transfer.
