In order to study if there are positive effects of using landmarks in a route guidance system, a field was carried out. Two groups of drivers had to drive to an unknown destination, following the directives from a simulated route guidance system that presented visual and verbal information. In the control group the subjects received left-right and straight ahead directives. In the experimental group the subjects received the same information plus information about landmarks on a total of six occasions. The landmarks were chosen to define more clearly directions, distances, and where to stop. The results showed some positive effects of landmarks presentation. The subjects in the experimental group were more satisfied experimental group were more satisfied with the content of the visual information, and were less unsure where to turn. Most important, they did not make any navigational errors. A number of suggestions for the improvement of the system was also obtained. (A)
