Abstract:This report documents the efforts and results of a two-year research project aimed at improving driveway
delineation in work zones. The first year of the project included a closed-course study to identify the most
promising driveway delineation alternatives for further study. In the second year of the research project, the
researchers performed a human factors study of alternative business driveway channelizing treatments in real
work zones. The purpose of the research was to determine the effectiveness of alternative business driveway
channelizing treatments over standard drum treatments. The alternative treatments included combinations of
18-inch tall low-profile longitudinal channelizing devices and 42-inch tall cones (i.e., grabber cones). Using
paid participants who drove a instrumented vehicles, the researchers used driver eye-tracking equipment to
compare differences in drivers’ visual attention while approaching business driveways with the various
channelization treatments deployed. Other measures of effectiveness (MOEs) considered were detection
distance, percentage of missed driveways, driver perception/recall of treatments, and driver preferences.
While differences in the MOE were less pronounced during the day, the alternative channelizing treatments
generally performed better than the standard drum treatment at night.
