Abstract:The purpose of the project was to develop a
temporary portable concrete barrier (PCB)
with an integral glare shield for use in
roadside work-zone areas. Currentlyavailable
32-inch portable concrete barriers
require the use of an add-on glare shield
attached to the top of the barrier. The addon
glare shields are an extra expense and
complicate barrier set-up and handling. The
solution was to develop a portable concrete
barrier tall enough to serve as its own glareshield,
thereby, providing an effective, low
maintenance solution for inhibiting
headlight glare and driver distraction in
work-zones.
