As intelligent transportation systems (ITS) become more available, drivers must cope with increasing amounts of in-vehicle information. While the intent of providing such information is to make driving safer and more convenient, the aggregate of all this new information may paradoxically decrease vehicle safety if good human factors principles are not used to implement ITS. This paper first discusses the need for ITS integration by reviewing two major new sources of in-vehicle information: collision avoidance systems (CAS) and advanced traveler information systems (ATIS). System integration is then defined in terms of system characteristics and their effects on the driver. ATIS guidelines illustrate first-level system integration. This paper concludes with a discussion of the safety implications of ITS.
