Automated Truck Mounted Attenuator (ATMA)Status: CompleteReport Date: 04/18/2025 Summary: Connected and automated vehicle (CAV) technology has the potential to significantly increase work zone safety. Each day, MnDOT maintenance employees and contractors are at risk of being involved in crashes when performing road work. To mitigate this risk, MnDOT uses truck mounted attenuators – or crash cushions – to help protect roadside workers. The ATMA project sought to evaluate and deploy automation technology in support of MnDOT maintenance work zones. The main project goal was to find a solution to improve worker safety by removing the human from the host truck, a position with high exposure to being hit by the traveling public. The ATMA project may not have accomplished the goals as originally defined but did expand MnDOT’s knowledge of automation technology, as well as develop understanding and support structure for how automation technology could be integrated into MnDOT’s fleet.
