Abstract
Workers in construction and transportation sectors are at increased risk for
work-related injuries and fatalities by nearby traffic. Barricade-mounted
warning lights meeting current specifications do not always provide consistent
and adequate visual guidance to drivers and can contribute to glare and reduced
safety. Through an implementation of sensors and wireless communications, a
novel, intelligent set of warning lights and a tablet-based interface were
developed. The lights modulate between 100% and 10% of maximum intensity rather
than between 100% and off in order to improve visual guidance and adjust their
overall intensity based on ambient conditions. The lights can be synchronized or
operated in sequential flash patterns at any frequency between 1 and 4 Hz, and
sequential patterns automatically update based on global positioning satellite
(GPS) locations displayed in the control interface. A successful field
demonstration of the system verified that its functions were viewed favorably by
transportation safety personnel.
