Learning Method of Communication Error Prevention

Preventing communication errors is essential for ensuring safety in the work place in railways. This study describes the construction of a "Causal model of communication errors in the railways" from the analyses of accident reports and feedback on experience of communication errors. Through this model, it was found that certain methods, such as "talk-back," "confirmation talk" and "learning ambiguous expressions" were effective in preventing communication errors. A training method to teach these skills was proposed and its effectiveness was confirmed through experiments.
