Abstract:This report documents the three Rockwell Precursor Systems Analyses of automated Highway Systems tasks of Lateral and Longitudinal Control Analysis, Malfunction Management and analysis, and Vehicle Operations analysis. The overall goal of the Lateral and Longitudinal control analysis task included performing system operational analyses in terms of safety and capacity and identifying issues and risks regarding the fundamental operations and maneuvers of vehicle control in a fully automated highway environment. The overall goal of the Malfunction Management and Analysis task included defining the boundaries of an AHS, establishing functional requirements, and suggesting potential configuration. then developing operational sequences through which functions are executed and identifying allocated subsystems were performed. Metrics to gauge severity levels of malfunctions were developed and used to assess malfunctions. similarities and differences between malfunctions and system configurations were examined to develop strategies to mitigate or avoid malfunctions and to raise issues and risks involved with the AHS. The overall goal of the Vehicle Operations Analysis task was to identify issues and risks associated with a fully automated AHS 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.
