Subway rail system is considered the best choice for big cities to solve surface transportation problems in terms of congestion, efficiency, and speed. The increasing use of these facilities by more and more passengers has made vital the need to ensure high safety standards. The effective structure of the evacuation plan in an emergency event is essential. A critical factor for a successful evacuation is the proper functioning of the egress paths that must be clear of any obstacles.

To ensure the passengers’ proof-of-fare (POF) public transport organizations have installed ticket validation machines proportionally in the facilities. In Athens METRO system, ticket gates providing automatic fare collection have replaced these ticket validation machines. Both POF systems may be considered as egress path obstructions that need to be taken into account in the initial evacuation plan design, since these POF installations provide different available width on the evacuation paths.

The paper investigates the impact of prior ticket validator and modern automatic fare collector machines on evacuation procedures in Athens METRO stations. The impact evaluation is based on three factors: i) total evacuation time, ii) time spent in queues (overcrowding effect) and iii) egress path flow rate, evacuation obstruction, human behavior.

地铁系统被认为是大城市解决地面交通拥堵、效率和速度问题的最佳选择。越来越多的乘客越来越多地使用这些设施，因此确保高安全标准变得至关重要。紧急事件中疏散计划的有效结构至关重要。成功撤离的一个关键因素是必须清除任何障碍物的出口路径的正常运行。

为确保乘客的票价证明 (POF)，公共交通组织已按比例在设施中安装检票机。在雅典 METRO 系统中，提供自动收费的检票口已经取代了这些检票机。两种 POF 系统都可以被视为在初始疏散计划设计中需要考虑的出口路径障碍物，因为这些 POF 安装在疏散路径上提供了不同的可用宽度。

本文调查了先前的检票器和现代自动检票机对雅典地铁站疏散程序的影响。影响评估基于三个因素：i) 总疏散时间，ii) 排队时间（过度拥挤效应）和 iii) 出口路径流速、疏散障碍、人类行为。
