Abstract:Turning into and out of driveways in confined or
dense urban work zones can present significant
challenges to drivers, especially during nighttime
conditions when other visual cues about the
driveways may be masked in the dark. These
challenges can lead to erratic behaviors by
drivers such as stopping in a travel lane or
making a sharp turn without proper turn signal
indications, and adversely affect safety and
mobility in the work zone. This project focused
on identifying alternative work zone delineation
strategies at driveways using various types of
work zone channelization devices, evaluating
these strategies in both controlled and field
conditions, and developing guidance for the
effective use of the high-performing channelizing
strategies at these driveways.
