In order to identify effective measures while confronted with limited time and budgets, priorities must be set according to the purpose and effect of a measure. The authors developed a "Human Error Risk management method". This is a method for evaluation which considers "the level of influence of the error-inducing factor" on a risk value evaluated by the combination of "possibility of being of an error" and "worst accident probable to occur due to the error". Consequently, a method for management of human error prevention is presented, which can be adopted by a rail track maintenance office. This paper introduces an example of its application to track maintenance.
