• Abstract:
  The objective of this research was to: I) identify or develop a speed monitoring display suitable for use in SDDOT interstate highway work zones, and 2) evaluate the display's effectiveness in reducing speeds in interstate work zones. A review of the literature and current practice was conducted to identify product availability and other state DOT's use. Speed monitoring display alternatives were identified and evaluated according to essential requirements and project evaluation criteria. The SDDOT selected a lidar laser radar device with a changeable message sign (CMS) to be tested. The selected device was installed and field tested. The before and after field data were analyzed to determine the effectiveness of the speed monitoring display in reducing speeds. The speed monitoring display was effective in reducing speeds higher than the lidar laser device setting of 70 mph. However, average travel speeds were not reduced.
