This chapter discusses human-system interface issues related to the design and use of Advanced Traveler Information Systems (ATIS). An ATIS is a subset of the more general transportation system being planned, known as the Intelligent Transportation System (ITS; see foreword and chapter 1 of this volume). The purpose of an ATIS is to regulate the flow of vehicles along roads and highways by using emerging sensor, computer, communication, and control technologies. Designing ATIS systems that humans can use safely and efficiently is a difficult undertaking. The difficulty is derived from a number of causes: (a) the inherent complexity of systems being planned or produced; (b) the widely ranging knowledge, skills, and abilities of the driving population; (c) the limited opportunities for training and instruction with regard to ATIS technology; and (d) the requirement that system use under all circumstances minimally interfere with the primary task of driving. To meet these challenges, a number of human factors issues must be successfully addressed.
