Intelligent Highway Vehicles:Vehicle Guidance and Navigation Systems

The combination of GPS (global positioning system) satellites, high-density computer storage of map data, electronic compass, synthetic speech synthesis, and computer-graphic displays allows cars and trucks to know where they are located on the Earth to within 100 m or less, and can guide a driver to a programmed destination by a combination of a map display and speech. Some human factor challenges are in deciding how to configure the map (how much detail to present, whether to make the map northup with a moving dot representing one’s own vehicle position or current-heading-up and rapidly changing with every turn). The computer graphics can also be used to show what turns to anticipate and which lane to get in. Synthetic speech can reinforce these turn anticipations, can caution the driver if he is perceived to be headed in the wrong direction or off course, and can even guide him or her how to get back on course. An interesting question is what the computer should say in each situation to get the driver’s attention, to be understood quickly and unambiguously but without being an annoyance. Another question is whether or not such systems will distract the driver’s attention from the primary tasks, thereby reducing safety. The major vehicle manufacturers have developed such systems, they have been evaluated for reliability and human use, and they are beginning to be marketed in the United States, Europe, and
Japan.
