• Abstract:
  This report documents research conducted in the evaluation of flashing arrowboards when located in advance of lane closure work zones. The effects of advance arrowboard placement were compared to the effectiveness of the arrowboard placement normally used by District 14 of the SDHPT. The research indicates that arrowboard placement in advance of the beginning of a taper can be extremely effective if the sight distance to the arrowboard improves the effective sight distance to the work zone. This improvement is dependent on the horizontal and vertical alinement of each work zone. From the distances evaluated, 2000 ft. in advance of the taper appears to be the maximum advance placement. Distances greater than 2000 ft. may result in drivers moving back into the blocked lane.
