Support for trouble-management behavior of a driver on a train without a conductor is more necessary than the case of a train with a conductor. The present study examined the effects of non-normal checklists on trouble-management behavior of a monorail driver. Three simulation experiments were conducted on actual monorails, and the effects of possession and use of checklists on the appropriateness, time spent, and passengers’ perception of the drivers’ trouble-management behavior were analyzed. The results are as follows : (1) the appropriateness of the behavior was not increased by possessing checklists alone, but was increased by appropriate reference methods such as pointing and checking, (2) the time spent on the behavior was not strongly related to appropriate use of checklists, (3) the drivers possessing checklists were perceived more negatively by the passengers. In order to use such checklists in practice, it may be necessary to clearly define an operations policy.
