• Abstract:
  The primary objective of this study was to evaluate the use of Portable Traffic Signal (PTS) systems at long, rural two-lane work zones and to compare three different conditions for controlling one-lane traffic in conjunction with pilot car operations: flagging only, a PTS system with the presence of a flagger, and a PTS system without the presence of a flagger. The primary measures of effectiveness were determined as Red Light Running (RLR) violation percentages, vehicle delay estimates, queue lengths, signal timing operations, and general field operations. Data were collected three days per week over a period of four weeks from August 5, 2014, to August 28, 2014, at four different temporary work zones in Kansas. Two PTS units were used for the purpose of the study in conjunction with pilot car operations.
