Each year more than 700 fatalities occur nationally due to vehicular accidents within work zones. New development and technologies have paved the way for the creation of diamond grade sheeting, a new, more retroreflective sheeting. Research has shown that diamond grade sheeting is 6 to 14 times brighter than engineering grade sheeting and is already widely required for use on work zone signs. However, the diamond grade sheeting is not widely required for use on channelizing drums due to the increased cost and concerns that the increased retroreflectivity of the sheeting may actually decrease the safety of the work zone when used on closely spaced construction drums. A comparative parallel study was conducted to compare the safety impacts of the diamond grade sheeting with high intensity sheeting, the current MUTCD standard Driver behavior within the work zone was analyzed in terms of lane placement and traveled speed with respect to the posted speed limit. These data were collected and analyzed to determine the extent to which the behaviors different between the two traffic control treatments. A current practices survey was also distributed to each state department of transportation to determine the extent to which diamond grade sheeting is being used.
