轮班制度对于地铁司机疲劳的影响

立足于轮班工作模式,阐述轮班制度对司机疲劳产生与积累的影响。介绍疲劳指数方法和池田公式的理论基础及模型构架,基于北京地铁13号线现行轮班表,分别应用上述两种研究方法进行地铁轮班司机疲劳程度的分析。两种方法的评估结果显著相关,均说明13号线现行轮班表的制定会导致司机疲劳的产生,存在安全运营风险。应用上述方法可实现对司机疲劳程度的非接触式测量,避免对司机驾驶作业的干扰,同时为地铁运营公司的安全管理人员制定合理的轮班方案,建立全面、量化的动态管理措施,提高行车安全保障提供了科学依据。

Influence of Shift System on Subway Drivers'Fatigue

Based on shift working mode,the influence of shift system on the producing and accumulating of driver's fatigue is elaborated.The theoretic basis and model framework of the fatigue index method and the Ikeda formula are introduced.According to the current shift form of subway Line 13 in Beijing,the fatigue level of the drivers is respectively analyzed with the above two methods.Both methods indicate that the current shift form will lead to the fatigue of the drivers and pose challenge to driving security.Applying the two methods can realize the non-contact measurement of drivers' fatigue level and avoid the interruption of driving work.It also provides a scientific basis for metro companies to design proper shift forms and improve driving security.
