Abstract

This paper reviews existing system-safety techniques in terms of their applicability to the current transportation structure, status, and available data; their ease of comprehension; and their usefulness in reducing accidents and fatalities. The two techniques of failure mode effects and criticality analysis and fault-free analysis are reviewed, explained, and modified for use in transportation safety studies. When applied at each level or activity cycle of a transportation system, these two techniques provide safety specialists with tools that lead to concern for safety at every stage of a project from conception through facility operation. The cohesive approach that is suggested by the concept of system safety is well-suited to the needs of transportation safety. As a methodology, system safety must be adopted and its technical and managerial analyses applied at the modal facility level.
