Recently, organizational factors are often discussed in analysis of human errors in working situations. In such contexts, a methodology to evaluate safety climate of organizations is proposed to promote appropriate safety management. This is composed of indices which evaluate various aspects of errors and accidents, and using which the safety climate is diagnosed. The indices are made by weighting the items of Accident Analysis Sheet (already developed by Railway Technical Research Institute) depending on contents and features of each error and accident. According to this methodology, several indices are experimentally formed, and the features of them and the points of consideration in interpreting calculated results are discussed. Finally linkage of the indices with the safety management supporting system now being developed is briefly touched.
