HIGHEST PRIORITY STUDIES/ISSUES
BRIEF DESCRIPTIONS OF STUDIES/ISSUES
A1. Examine the cognitive demands placed on the driver by the need to transition from one ATIS function to another
A4. Identify how complex ATIS interactions among ATIS functions might affect driver understanding and response to the system
B3. Identify how the information drivers need and want from road sign (ISIS) and warning systems (IVSAWS) might influence behavior
C4. Examine how information reliability (e.g., false alarms) influences driver adaptation and enhance the potential for an improper response to ISIS/IVSAWS
C5. Investigate how to display multiple ISIS and IVSAWS messages so that drivers can identify relevant information and react appropriately
D2. Identify features that will benefit/require standardization across many types of ATIS systems and functions
D4. Examine the performance differences associated with focusing all ISIS and IVSAWS information through either single or multiple display channels
D12. Evaluate the effectiveness of multimodality displays, such as voice in combination with text
D17. Identify specific concerns regarding how display formats and modality impact CVO driver workload
