This project hosted a demonstration of the operation and function of the autonomous truck-mounted attenuator (ATMA) in a closed loop environment as well as in an active work zone. This will provide a hands-on opportunity for stakeholders to experience this state-of-the-art equipment. ATMA has the potential to reduce the risk involved in roadway construction and maintenance. The demonstration has also tested the feasibility of the technology and its application for falling weight deflectometer equipment.

Benefit Cost (BC) Analysis Tool: A spreadsheet tool was developed as part of this study. Click the link below to download the BC tool.
Establishes ground truth – the video provides an opportunity for the analyst to visually inspect and correlate the traffic characteristics (speed, acceleration, etc.) with the data log retrieved from ATMA.
GPS position of vehicles in road network
Provides location of vehicles (points) on primary road network (lines) for visual inspection. It helps to qualitatively understand the impact of road network elements such as intersection etc.
Time and status
Since several equipment are used in the data collection effort, this plot helps in reviewing the time component and the associated status of the follower ATMA. Info on different navigation status can be found in the final report.
Speed vs time and distance vs time plot
These plots quantify the instantaneous speed and distance travelled of leader and follower with respect to time.
