An experiment designed to assess the ability of subjects to plan long trips in unfamiliar areas by using only maps is described. The experiment was part of a larger study intended to describe and quantify the excess-travel problem in the United States. Subjects were asked to plan relatively long trips in unfamiliar areas by using only a road atlas. The sample was designed to represent the age and sex distribution of the U.S. driving population. The routes selected by the subjects were compared with the routes recommended by the American Automobile Association (postulated to be "optimum") for both distance and approximate driving time. Analyses of the data indicated that the excess distance of the routes selected by the subjects, on average, increased trip length by 12.1 percent. Age, sex, and geographic location of subjects had little effect on their performance.
