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.
