摘要：	This report describes an investigation of driver preferences and usability of adjustable distance controls for an adaptive cruise control (ACC) system. ACC is conceived as an enhancement to conventional cruise control that would accommodate a slower moving vehicle in the lane of travel by providing some moderate level of deceleration and distance maintenance behind the slower vehicle. While the ACC system is maintaining a distance behind a slower vehicle, there is the possibility for the driver to adjust the following distance according to his/her preferences. In this study, thirty-six participants (equal numbers of men and women grouped according to ages 25-39, 40-54, and 55 and over) were Introduced to the concept of ACC by using a computer prototype of an ACC system.Participants were asked to provide their preferences for labels for two types of adjustable distance controls: one type that adjusts both speed and distance (shared controls) and another that adjusts only distance (separate control).They also used the controls to get closer and farther away from a slower vehicle in front of them and provided their preferences for shared or separate controls for distance adjustment. Participants preferred shared controls to a separate control for distance adjustment. They preferred the labels ACC/DEC for shared controls over +/- and ACC/COAST. The labels preferred for the separate control were NEAR/FAR as opposed to symbols (arrows or chevrons).Because these preferences were obtained through the use of a computer prototype of ACC, usability tests should be conducted on the road to validate the data.
