• 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.
