摘要

This report is the final documentation in a series describing an effort todetermine a viable approach to ensuring that the elements of such an Automated Highway System (AHS) are ensured operational, or healthy. The system which performs this assessment, and intervenes if an element is found wanting, we will term a Health Management System. Assessing the health of the vehicle, its operator and the associated infrastructure prior to entry into instrumented mode (check-in), again prior to entry into manual mode (check-out), and the actions to take when either of those assessments are found wanting (malfunction management) are the primary elements of a total health management system (HMS). Previous papers have presented the scenarios and functions, function criticality assessment, allocation, and preliminary mechanization analysis. This paper will present a brief overview of the process used to perform the Health Management study, followed by a discussion of the results produced in this period of performance, including detailed mechanizations of vehicle and roadside functions, reliability and safety analyses, vehicle simulations, and a driver check-out analysis.
