Strategies to Reduce Truck Mounted Attenuator Crashes

The objective of this project is to identify the most promising methods that could reduce the occurrence and severity of truck mounted attenuator (TMA) crashes in construction and maintenance work zones, including both stationary and mobile operations. The research team will investigate methods to improve safety such as increasing the conspicuity of TMAs, including changes in markings, colors, or lighting; changes in traffic control devices; changes in the location, staging, or setup of TMAs for different work zone configurations; improvements in operator training; methods to improve the safety of the TMA operator in the event a collision does occur; and connected vehicle applications that provide vehicle-to-vehicle warnings and pre-collision alarms or advance notice of the TMA’s location for oncoming drivers.
