RES2019-15: Autonomous Truck Mounted Attenuator (ATMA) Pilot

The objective of this research was to provide the Tennessee Department of Transportation (TDOT) an evaluation on the performance of an autonomous truck mounted attenuator (ATMA) system(s), based on previous relevant research projects and on actual testing of the equipment during a demonstration pilot. A set of testing scenarios were developed in close collaboration with TDOT to better understand the feasibility and applicability of the ATMA system to improve safety on work zones in Tennessee. The ATMA pilot demonstration testing in Tennessee concluded primarily that the ATMA system is better suited for work zone operations that require continuous movement for longer periods of time. Retracing or installation of pavement markings and roadway sweeping are examples of such operations. Based on the pilot results, the tested ATMA system warrants further development and testing for work zones requiring stop-and-go applications. Pothole patching, weed spraying and trash pick-up on the roadway shoulder are examples of such operations. The ATMA system presents technological advancements that increase safety in work zones. It can be further enhanced by future refinement and implementation of additional system functionalities.
