Use of Speed Monitoring and Communications Display for Traffic ControlAuthor/Presenter: Wertjes, Jon Micheal
The objective of this research was to: 1) identify or develop a speed monitoring display suitable for use in interstate highway work zones, and 2) evaluate the display’s effectiveness in reducing speeds in interstate work zones. Speed monitoring display alternatives were identified and evaluated according to essential requirements and project evaluation criteria. A lidar laser radar device with a changeable message sign (CMS) was tested. Testing revealed that 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.
