Abstract

The objective of this study was to use and evaluate various SHRP work zone devices. Experience with the use of these devices was obtained through trial use by the Kentucky Transportation Cabinet and various city, county, and private agencies. The devices included in the study included:

  • Flashing Stop/Slow Paddle
  • All-Terrain Sign and Stand
  • Portable Rumble Strip
  • Opposing Traffic Lane Divider
  • Intrusion Alarm

The experience with the flashing stop/slow paddles was very positive indicating the potential for expanded use in the future. Six different models of flashing paddles were evaluated with some having better results than others. While the all-terrain stand and sign was effective, its future use is limited by both its cost and difficulty to use. The use of the portable rumble strip will be limited by its difficulty to use, related to both its weight and inability to stay in place on high speed roads. The opposing traffic lane divider shows potential for use as a supplement to the standard tubular marker but must be used at locations where it is not routinely hit by traffic. Lane dividers from three manufacturers were tested with varying degrees of success. The intrusion alarm has the potential for use on major projects with its cost limiting its use. The continuing modifications made to the intrusion alarms during the study period made it difficult to obtain a complete evaluation or recommendation for a specific unit. Intrusion alarms from five manufacturers were evaluated.
