APPLICATION OF EXISTING HUMAN FACTORS GUIDELINES TO ATIS
Francine H. Landau Martha N. Hanley Cheryl M. Hein Hughes Aircraft Company
This chapter evaluates the applicability of current human factors guidelines to an Advanced Traveler Information System (ATIS). The system goals are to acquire, analyze, communicate, and present information to assist both commercial and private drivers in moving from one location to a desired destination. This navigation information is provided in the vehicle and includes emergency, congestion, hazard, and "yellow page" categories of information. Although there are currently many worldwide efforts to research, develop, and implement in-car navigation systems, there are no clearly stated design requirements to help the system designer optimize this driver- vehicle interface. Without utilizing good human factors practice and judgment in the design of such systems, the result would surely tax the abilities of most drivers and possibly cause unsafe situations where none exist today. As an initial step in the new system design activity, human factors practitioners consult existing guidelines as an aid in defining the functionality and form of the new system. At the same time, they must determine if the guidelines are appropriate for the new implementation, and what, if any, caveats or complementary research must be considered. To this end, this chapter will describe ATIS functionality, driver-vehicle interface components, and existing guidelines with discussion and recommendations concerning their limitations and research needs.
