C.14 Highway Signs. A driver’s ability to detect highway signs is an important consideration in highway safety. In his dissertation Highway Construction Safety and the Aging Driver (1994), Solomon Younes investigated the distance at which drivers can first detect highway caution signs. This distance is called the detection distance. An experiment was conducted to determine the effects that sign size and sign material have on detection distance. Four drivers were randomly selected for each combination of sign size (small, medium, and large), and sign material (1, 2, and 3). Each driver covered the same stretch of highway at a constant speed during the same time of day, and the detection distance (in feet) was determined for the driver’s assigned caution sign. The data in the following table are based on the results of the experiment.
