Railway controllers play a pivotal role in service recovery of normal rail system operations when incidents and accidents occur. Those in this position must have sufficient competence to overcome task difficulties caused by accident uncertainties. This study adopts Taiwan's railway system as a case study to diagnose railway-controller-perceived competence when facing diverse tasks during incidents and accidents that are derived from a proposed conceptual model. Railway-controller-perceived competence is measured using the Rasch model. Analytical results indicate that working with an external rescue agency handling a rescue operation, explanations to the public, and communication with an external rescue agency are considered the most troublesome tasks. Additionally, railway-controller-perceived competence differs based on the work experience. This information will prove useful for rail system operators and government regulators when designing and regulating railway controller competence management systems. STATEMENT OF RELEVANCE: This study presents a systematic approach for examining the gap between railway-controller-perceived competence and task difficulties associated with incidents and accidents. The relevance of findings encompasses the effects of transportation ergonomics and railway issues on the problem-solving competence and decision-making skills of railway controllers, and the competence management system.
当事故发生时，铁路调度员在正常铁路系统运行的服务恢复中起着关键作用。该岗位的工作人员必须具备足够的能力，以克服事故不确定性所带来的任务困难。本研究以台湾铁路系统为例，通过一个拟议的概念模型，对事故和突发事件中铁路调度员感知到的不同任务的能力进行诊断。使用 RASCH 模型对铁路调度员感知能力进行测量。分析结果表明，与外部救援机构合作处理救援行动、向公众解释以及与外部救援机构沟通被认为是最麻烦的任务。此外，铁路调度员感知能力还因工作经验而异。这些信息对于铁路系统运营商和政府监管机构设计和监管铁路控制器能力管理系统将非常有用。
本研究提出了一种系统的方法来检验与事故和突发事件相关的铁路调度员感知能力与任务难度之间的差距。研究结果涉及交通工效学和铁路问题对铁路调度员解决问题能力和决策技能以及能力管理系统的影响。
