• Abstract:
  This report documents the efforts and results of research to evaluate the effectiveness of alternatives to the ; use of channelizing drums for driveway delineation in work zones. The Florida Department of ; Transportation (FDOT) had originally sought to investigate the use of blue-striped channelizing devices but ; ultimately decided to examine the effectiveness of low-profile longitudinal channelizing devices (LCDs). ; LCDs are already an accepted device in the Manual on Uniform Traffic Control Devices and so would not ; require changes to the manual in order to be used on projects. The LCDs were compared against standard ; drum delineation in both a closed-course study and a field study in Florida work zones. The researchers used ; erratic maneuvers, speed profiles, and driveway user surveys as measures of effectiveness. The results ; indicated that there were no significant differences in the erratic maneuvers and speeds of turning vehicles ; that were attributable to the treatments. However, the survey results showed that drivers prefer LCDs over ; drums for helping them identify driveway openings. Meanwhile, other studies outside of Florida have shown ; that using LCDs instead of channelizing drums at a driveway improves driver ability to locate that driveway. ; Considered in total, researchers recommend that FDOT consider modifying its driveway delineation standard ; to allow LCD use. The standards should include requirements that they be delineated and that they be ; properly ballasted.
