Development of Functional Requirements for a Highly-Mobile Barrier System to Protect Highway Workers: Interim Report

Many work zone devices, such as truck-mounted attenuators (TMAs), cones, and barrels, are used to separate workers from the traveling public during construction and maintenance activities. However, these devices do not provide lateral impact protection. This research project is being conducted to investigate the feasibility of developing a highly-mobile lateral protection system. This interim report documents the work completed to date for Tasks 1-4. (Task 1 – Categorization of Construction and Maintenance Activities; Task 2 – Discussion of Historical Research on Mobile Worker Protection Systems; Task 3 – Assessment of Road Work Environment Constraints; Task 4 – Characterization of Physical Impact Conditions)
