• Abstract:
  Transportation agencies, contractors, researchers, and private vendors are actively looking for new methods and devices ; to help make construction and maintenance work zones safer while maximizing mobility. Short-term and short-duration ; work zones are no exception, especially as fewer devices can be used in a practical way than in long- term work zones due ; to the limited installation time available. Practitioners commonly cite the challenge of using traditional devices for ; protection, as installation costs are high relative to the project and it may take longer to install the devices than perform ; the planned activities. This situation creates the need for more portable positive protection devices in lieu of traditional ; devices (such as temporary concrete barrier or “TCB”) that are commonly used on long-term projects, but can’t be ; repositioned easily. ; So what do we mean by “portable positive protection?” For purposes of this guide, ; this label applies to highly mobile and movable steel barriers that provide ; acceptable crashworthy levels of protection – like that of temporary concrete ; barrier – but are much more portable and relatively quick to install and remove ; when compared to more traditional devices. While temporary concrete barrier is ; generally considered a device for use on long term projects (those lasting more than ; 3 days), the definition of portable for the purposes of this guide is a device that is ; feasible for shorter work operations. Portable devices are available that can be ; easily placed and removed (or moved from the travel way) to provide protection for ; short-term and short-duration operations. Portable devices mentioned in this guide ; may be used on long-term projects as well since many of the work zones in use could ; vary from short to long duration
