Perspective In Orientation/navigation Displays: A Human Factors Test

Twelve drivers (6 ages 18-30.6 over 65) participated in an experiment While seated in a vehicle mockup, they were shown slides of residential intersections photographed from the drivers viewpoint. Simultaneously, drivers saw slides of a navigation display. Drivers indicated if the two hages were for the same or different type of intersection (cross. Y. T, etc.). ?he response times indicated that Head-Up-Display-mounted displays were better than consolemounted displays (1524 versus 1630 ms). that aerial views were slightly better than plan views (1501 versus 1523 ms) and much better than perspective views (1706 ms). Finally. responses to displays where the roads were shown as solid objects were more rapid than to those shown as outlines (1557 versus 1597 ms). Emr and preference data supported these results. The results from this experiment should be validated with on-road data.

Human Factors Research on Future Automotive Instrumentation: A Progress Report

This paper describes a 2–1/2 year project concerning human factors and future driver-information systems. The project goals are to (1) develop human factors guidelines, (2) devise test methods for safety and ease of use, and (3) develop a model that predicts driver performance when using these systems. A literature review has been completed and focus groups that identified driver needs have been conducted. In addition, a method was developed to select the most beneficial systems using accident reduction, congestion relief, and driver needs/wants as the criteria. Consequently, car phones, navigation, traffic information, vehicle monitoring, and hazard warning systems were selected for further study. Preliminary versions of each have been designed and laboratory tests are in progress. Usability tests in a driving simulator and on the road are scheduled.

What functions and features should be in driver information systems of the year 2000

This paper describes new driver-information systems that are suggested for cars of the 21st century and proposes a method for selecting them. This method will help government officials, product planners, engineers, designers, and scientists identify functions and features that will be most beneficial to drivers. The systems (functions) of interest were navigation, vehicle monitoring, traffic information, road-hazard warning, communications, motorist services, in-car signing, office functions, and entertainment. Features and information elements of these systems were identified and rated on three dimensions: effect on accidents, impact on traffic operations, and driver needs and wants. Based on the ranking of features, information about slick roads, accidents, congestion, construction, blocked views, emergency vehicles, and tire and brake problems would be particularly beneficial.
