Abstract:

Work zone safety has been a major concern for many stakeholders, including the state Departments of Transportation (DOTs). To prevent DOT workers, especially truck mounted attenuator (TMA) drivers, from injuries, the Autonomous Truck Mounted Attenuator (ATMA) technology was developed. To understand the current testing and deployment status of ATMA, we interviewed project managers and researchers in four state DOTs who had experience with the ATMA system. We then systematically reviewed, tested, and evaluated the ATMA system in both simulation and real-world environments under various operating scenarios, traffic conditions, and mobile work zone operations. Indiana Department of Transportation (INDOT) workers’ perception of using the ATMA system was also collected. Results suggested that the ATMA system can be successfully implemented in most of the selected INDOT road maintenance activities with good performance. INDOT workers were also comfortable to operate the ATMA system after training and welcomed this new technology. Longer exposure to the ATMA system was a key factor impacting workers' behavior and evaluation toward ATMA. While the ATMA system demonstrated significant benefits in saving transportation workers' lives and reducing their risk of injuries; however, one limitation was that the system’s cost is relatively high at the current stage, based on a cost-benefit analysis.
