Use of truck-mounted attenuators in short term/mobile lane closures: operator perspectives in southeast Queensland

Truck-mounted attenuators (TMAs, e.g. Figure 1) are deployed to provide positive protection for roadworkers and reduce the impact of vehicle intrusions into work zones. The aim of this research was to explore operational issues and perceived effectiveness of TMAs from the perspective of TMA operators in Queensland, Australia. Participants perceived TMA deployment procedures as sufficient overall, but concerns were expressed about lack of driver awareness, inappropriate driver behaviour, and consistency of deployment. In the first research focusing directly on driver behaviour and TMAs in Australia, the interviews revealed TMA operators’ perspectives on risks and hazards associated with TMA use, as well as the supporting safety measures deemed most effective.
