The information for generating the accident cause degree selection item display screen includes information on work problem items input in advance by an administrator or the like, information on the accident cause degree selection item, and the like.

  The work problem item information is a sentence indicating a matter that may cause an accident with respect to the target work (maintenance work of the railway track in the present embodiment). For example, in the present embodiment, the work problem items are “the worker leaves it as it is even if there is a question in the contents of the instruction”, “the worker pays attention to the person in charge of the work who does not pass the diamond to the watchman. It is a sentence such as “No”. The information on the accident cause selection item is a sentence representing the degree to which the work problem item is caused by the accident. For example, in the present embodiment, the accident cause selection item is a sentence such as “does not directly lead to an accident” or “does not train derailment / overturn”.

  Then, the user uses the accident cause degree selection item display screen to select a work problem item and an accident cause degree selection item (hereinafter referred to as an accident cause degree selection item) indicating the degree to which the work problem item is caused by an accident. ), A check box related to is selected, an accident cause selection item corresponding to the work problem item is selected, and a save button is pressed.
