PRECURSOR SYSTEMS ANALYSES OF AUTOMATED HIGHWAY SYSTEMS - AHS PSA VEHICLE OPERATIONS ANALYSIS

The overall goal of this task was to identify issues and risks associated with an Automated Highway System (AHS) fully automated vehicle. The primary issues that were addressed were related to vehicle-infrastructure functional decomposition, performance requirements, fail-safety and criticality, communications, self-monitoring and self-diagnosis technology, and overall vehicle management. Specifically, this task had four primary objectives: (1) What new vehicle subsystems are required to meet the functional requirements of AHS including sensors, processing, and vehicle to vehicle communications and vehicle to infrastructure communications? (2) What subsystems have reliability issues that can have a significant impact on AHS operation and safety? (3) Can the reliability of these subsystems be improved through new design or redundancy? (4) Is it sufficient to perform subsystem checkout at start up or will a self diagnosis system offer greatly improved safety and fail-soft capability? Will additional subsystem sensors be required?
