Selection of Work Zone Channelizing Devices Using the Value Engineering Approach (abridgement)

The use of value engineering for selecting work zone channelizing devices is investigated. For illustration, the approach is used to select devices for a lane closure taper at a rural freeway work zone. The results of the investigation indicate that value engineering can be a useful and practical work zone traffic management tool. It provides an objective means of evaluating any number of alternative channelizing devices using whatever performance and cost data are available. Most important, it encourages the selection of low-cost devices that are safe and effective under the prevailing work zone conditions.
