SPR-4630: Implementation Exploration of Autonomous Vehicles: Impacts of Autonomous Truck-Mounted Attenuator (ATMA) on INDOT Work Zone Safety, Mobility, and Crews’ Perception/Behavior/Productivity

Utilization of Autonomous Truck-Mounted Attenuator (ATMA) is believed to protect crews and drivers from crashes caused by reckless and distracted drivers. This study will develop a tailored ATMA plan based on observations from existing TMA operations, Indiana Department of Transportation (INDOT) crews’ perception of ATMA and characteristics of ATMA’s operation environment in Indiana. The project will evaluate the ATMA in field tests and provide recommendations for implementation.
