“…Fleischman, Thelen, and Dennard (1993) reported that rental field study drivers used turn-by-turn visual and supplementary voice most of the time when using the route guidance function of TravTek. The results reported in this paper show that the percentage of use of the turn-by-turn and voice configurations increased with increasing age.…”

This paper explores the effects of age, system experience, and navigation technique on driving, navigation performance, and safety for drivers who used TravTek, an Advanced Traveler Information System. The first two studies investigated various route guidance configurations on the road in a specially equipped instrumented vehicle with an experimenter present. The third was a naturalistic quasi-experimental field study that collected data unobtrusively from more than 1200 TravTek rental car drivers with no in-vehicle experimenter. The results suggest that with increased experience, drivers become familiar with the system and develop strategies for substantially more efficient and safer use. The results also showed that drivers over age 65 had difficulty driving and navigating concurrently. They compensated by driving slowly and more cautiously. Despite this increased caution, older drivers made more safety-related errors than did younger drivers. The results also showed that older drivers benefited substantially from a well-designed ATIS driver interface.

“…Of the rental drivers surveyed, most preferred route map with voice and guidance with voice. Fewer preferred the route map without voice and guidance without voice, and the fewest preferred voice only (Fleischman, Thelen, and Dennard, 1993).…”

This report is one of a series produced as part of a contract designed to develop precise, detailed, human factors design guidelines for Advanced Traveler Information Systems (ATIS) and Commercial Vehicle Operations (CVO). The contractual effort consists of three phases: analytic, empirical, and integration. This report is a product of the analytic phase. Among the other analytic topics discussed in the series are ATIS and CVO system objectives and performance requirements, comparable systems analysis, ATIS/CVO functions, task analysis, alternate systems analysis, driver acceptance, identification and exploration, and definition and prioritization of research studies. This report identifies information display format alternatives for in-vehicle devices for both private and CVO applications and presents a set of human factors design tools designers can use to develop safer and more effective ATIS displays. Also reported are research issues still requiring attention in order to further the goal of this project and to develop useful information format guidelines.

“…The delays result in significant waste of time and resources, and can have life-and-death consequences when emergency vehicles are delayed. For instance, the TravTek system, a joint public and private sector venture that recently completed operational field tests, provided a fleet of 100 rental cars in the Orlando area with onboard route selection, route guidance, and navigation information, among other services (Peters et al, 1993;Fleischman et al, 1993) . In 1987, the total delay on America's urban freeways exceeded two billion hours per year, with an estimated cost of 15.9 billion dollars, and these numbers increase as the number of vehicles increase .…”

Traffic congestion is becoming a severe problem in many large cities. and several Intelligent Transportation Systems (ITS) initiatives have been proposed to address this problem. Providing automated route guidance is an important feature of many of these programs; however, the aspect of providing route guidance based on past experience has received little attention. We propose a system based on case-based reasoning to provide such guidance with minimal recomputation. Case-based reasoning stores instances of previous problem solving and then adapts them to new situations. We describe the architecture and implementation of the system and evaluate the performance of the system on a series of tests. We find that when the system can adapt previouslycomputed routes to solve new problems, solution time is greatly reduced.
