Development of Human Factors Guidelines for Advanced Traveler Information Systems and Commercial Vehicle Operations: Comparable Systems Analysis
The richness of information and multiplicity of functions that TravTek offers have the potential for causing information overload for the driver. Therefore, human factors engineering of the information displays and controls was a team priority from the early conceptual stages of the project (Carpenter et al., 1991). The intended users of the field–test system (travelers and local residents) had minimal opportunity for training. Throughout design and development, an overriding consideration was to make the system as easy to learn and easy to use as possible.
The cognitive demands, as determined by preliminary TravTek evaluation results, are discussed in detail in a subsequent section.
