Abstract:The Florida Department of Transportation’s Design Standards requires placement of business
entrance signs and channelizing devices at business entrances in work zones. The Design
Standards also specifies the layout of the signs and devices. Typically, highway contractors use
orange and white plastic drums as channelizing devices. However, these drums are also used
to mark other areas of work sites.
The Design Standards requires
that drums be spaced more
closely at business entrances, but
in field experience, this does not
appear to aid driver detection of
entrances. The additional drums
at entrances may also contribute
to the visual clutter of work sites
and impair sight lines for drivers
exiting businesses.
