PRECURSOR SYSTEMS ANALYSES OF AUTOMATED HIGHWAY SYSTEM. FINAL REPORT. VOLUME 8: VEHICLE OPERATIONAL ANALYSIS

This document is Volume 8 of the final report on precursor systems analyses of the Automated Highway System (AHS). It analyzes the reliability requirements and issues associated with the development, operation and deployment of vehicles for five evolutionary representative system configurations (ERSCs) of AHSs. The ERSCs are chosen so that the number of automated vehicle and roadway functions increases from ERSC 1 to ERSC 5 where fully automated vehicles are guided by the roadway. The emphasis of the report is on the issues associated with the evolution of vehicle control, reliability and safety, vehicle and driver diagnostic requirements, maintenance, retrofitting, and deployment scenarios for each ERSC. The report documents the results of a failure modes and effects analysis (FMEA) that includes a list of potential failure modes, their potential causes and effects, their severity and occurrence ratings and a list of design requirements and recommendations for each ERSC. The results of the FMEA indicate that the reliability requirements are becoming higher and higher as the level of vehicle automation increases from one ERSC to a higher ERSC. These requirements call for a considerable number of redundancies and on board diagnostics that increase the complexity of the vehicle considerably. The current sensor technology cannot meet the design requirements for reliable automated vehicle operation and yet remain within reasonable cost constraints. In addition to reliability, the report discusses key issues associated with vehicle and driver diagnostics, maintenance, retrofitting as well as the feasibility of deploying automated highway systems in stages by following an evolutionary path.
