Abstract This report provides a systems approach to the assessment, evaluation and application of high-speed guided ground transportation (HSGGT) safety criteria and presents one potential methodology by combining a work breakdown structure (WBS) approach with an interface evaluation methodology. By systems approach i£ is meant that safety considerations and criteria are tied to an HSGGT structural concept and are addressed from the highest level of a system hierarchy downward in a WBS. Safety criteria can then be logically associated with each system structure. This is a departure from the traditional approach of assessing safety issues individually and in isolation of other factors. The generic work breakdown structure (WBS) developed by The Defense Systems Management College and outlined in its publication, System Engineering Management Guide, was selected to structure the complex configurations of a generic maglev system and a generic high speed rail (HSR) system. Both WBS provide a system approach to the assessment of the need for and application of safety regulations in the field of high-speed guided ground transportation (HSGGT). A typical generic WBS is composed of segments, elements, subsystems, and components, but the maglev and HSR WBS presented in this report are defined to the subsystem level only, allowing for further lower level definitions at a later time. Each WBS is organized on the basis of providing mutually exclusive segments on a technological basis at least to the maximum extent that is reasonable. A methodology known as n-1 is used to describe a means to create diagrams that depict the interface between segments, elements, and subsystems. A total of 129 subsystems are identified for a generic maglev system and 118 are identified for a generic HSR system.
