Abstract

Stations are the main components of the subway systems. Despite the progress in the construction and maintenance, stations have always been exposed to the natural and man-made disasters. In such incidents, the station’s evacuation capability has a direct relation with a passenger's life. Various factors affect the station's evacuation capability. Investigation of these factors and evaluation of the station’s evacuation capability have important roles in protecting a passenger's life. For this purpose, the catastrophic events that lead to the evacuation of a station and the factors affecting the evacuation of the station are identified. Due to the difference in the catastrophic event probabilities at each station, the risk of catastrophic events is evaluated. Then the station score is calculated according to the value and weight of the evacuation factors and the wighted influence of the catastrophic events. Accordingly, the proposed model is implemented in the Tehran subway. Based on the results obtained, uncrowded stations, even though served by a small number of passengers, may also have a low evacuation capacity and lead to casualties in an emergency situation. This is due to the lack of emergency management and safety facilities. Also by assessing the risk of catastrophic events at stations and equipping stations on its basis, the degree of safety and evacuation capability can be improved more effectively. The sensitivity analysis of the evacuation factors show that the most effective way to increase the station’s evacuation capability is to improve its status in management factors. Using the proposed model to evaluate the station's evacuation capability is an appropriate method for identifying the stations that have a poor evacuation capability.
基于疏散能力的地铁车站分级方法:一种定量方法
车站是地铁系统的主要组成部分。尽管在建设和维护方面取得了进展,但车站总是暴露在自然灾害和人为灾害中。在此类事件中,车站的疏散能力直接关系到乘客的生命。各种因素影响车站的疏散能力。对这些因素的调查和车站疏散能力的评估对保护乘客的生命安全具有重要作用。为此,确定了导致车站疏散的灾难性事件以及影响车站疏散的因素。由于每个站点的灾难性事件概率不同,因此对灾难性事件的风险进行了评估。然后根据疏散因素的值和权重以及灾难性事件的影响来计算车站得分。因此,所提出的模型已在德黑兰地铁中实施。根据所获得的结果,即使有少量乘客服务,但未拥挤的车站也可能具有较低的疏散能力,并在紧急情况下导致人员伤亡。这是由于缺乏应急管理和安全设施。此外,通过评估车站发生灾难性事件的风险并在此基础上为车站配备设备,可以更有效地提高安全程度和疏散能力。疏散因素的敏感性分析表明,提高车站疏散能力的最有效方法是提高车站在管理因素中的地位。使用所提出的模型来评估车站的疏散能力是识别疏散能力较差的车站的合适方法。
