An Assessment of Moving Map and Symbol-Based Route Guidance Systems

Route guidance systems are in-vehicle electronic devices that aid drivers in choosing and maintaining efficient routes. Since the initial development of these systems, human factors practitioners have expressed concern over possible safety-related implications (e.g., Barrow, 1990; Dewar, 1988; Parkes, 1991). Whereas route guidance systems should support drivers in the navigation task and reduce workload, they also carry the potential for information overload and distraction, with the subsequent consequences of poorer driver performance and decreased safety.
Large programs, such as Prometheus and DRIVE in Europe and IVHS in North America, have supported research into a wide range of human factors issues associated with the design of route guidance systems. Given the imminent widespread introduction of these systems, it is important that research results are rapidly translated into usable design recommendations and guidelines.
Previous human factors work regarding the presentation of information by route guidance systems has typically been of two types. First, researchers have conducted experimental work in laboratories, in simulators, or on roads, examining specific design issues. Such issues can be classified into three broad areas of concern:
