Look Ma, No Hands!

摘要

This truck has no driver. What's more, it's a safety vehicle. One of the most dangerous workplaces in the construction industry is on an active roadway. As reported in the article on page 18, high-speed vehicles crashing into work zones is a huge concern to the highway construction industry and state DOTs nationwide. One widely used safety measure is the truck-mounted attenuator (TMA), a sacrificial impact-absorbing device mounted on the rear of a truck that can be parked at the beginning of a roadway jobsite. In the case of a moving work zone, such as a line-painting operation, the TMA truck follows at the end of the work party, constantly protecting the rear of the team.
