PRECURSOR SYSTEMS ANALYSES OF AUTOMATED HIGHWAY SYSTEMS. FINAL REPORT. ACTIVITY AREA N: AHS SAFETY ISSUES

The issues of automated highway system (AHS) safety are addressed from a system design standpoint. Four general areas of concern: failure prevention in the areas of vehicle subsystems, infrastructure instrumentation, and roadway mechanics; implementation of complex systems in terms of reliability and redundancy; structured methodologies for supporting systems assurance; and collision avoidance in the presence of external disruptions, are discussed. The tradeoffs involved in maintaining a certain level of safety using the most effective approach are addressed. The implications of system configuration in terms of headway maintenance policy and coordination units are presented. Examples are used to illustrate the relative vulnerability of each representative system deployment to a variety of hazards. Recommendations are made concerning specific systems configurations attributes which have significant impact on system safety requirements.
