FOREWORD
This report is
one of a series of reports produced as part of a contract designed to
develop precise, detailed human factors design guidelines for Advanced
Traveler Information Systems (ATIS) and Commercial Vehicle Operations
(CVO). The contractual effort consists of three phases: analytic, empirical,
and integrative. This report is a product of the empirical phase. The
empirical phase will also address topics such as: ATIS function transition,
display channels, multi-modality displays, CVO driver fatigue, display
formats and workload, and head-up displays (HUDs). Among the analytic
topics discussed in the series are functional descriptions of ATIS/CVO,
comparable systems analysis, task analysis of ATIS/CVO functions, alternate
systems analysis, identification and exploration of driver acceptance,
and definition and prioritization of research studies.
This report documents
a study that was performed to investigate the following issues: (1)
the influence of an ATIS on driver performance in reduced visibility
conditions, (2) the influence of an ATIS on drivers' reactions to unexpected
roadway events, and (3) the interaction of an ATIS with a Collision
Avoidance System (CAS).
