Automatic Audio Signing Volume II. Review Analysis and Design, Phase I

摘要

This report documents the activities, findings, conclusions and recommendations of the first of three phases of a project directed toward the development of an automatic audio signing system. Also referred to as 'automatic highway advisory radio' (AHAR), its objective is to facilitate aural roadside-to-motorist communications without diverting the motorist from the task of driving. The report summarizes the results of the principal tasks performed, which were: (1) review of prior and ongoing audio signing systems, (2) development of functional specifications, (3) conceptual design (4) analysis of conceptual design, and (5) system design. The research approach, findings and key task outputs are discussed.
