This report investigates the use of value engineering for selecting work zone channelizing devices. Presented first is a State-ot-the-Art review of available channelizing devices and their relative performance. Next, an overview of the Value Engineering problem-solving approach is presented. The paper then demonstrates how the Value Engineering approach can be applied to select work zone channelizing devices. For illustration, the approach is used to select devices for a lane closure taper at a rural freeway work zone. Based on the results of the investigation, Value Engineering appears to 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 which are safe and effective under the prevailling work zone conditions. The investigation further suggests that the Value Engineering approach is most appropriate for use at the Division level. It is an effective analytical tool which can be used in developing standards and for resource planning and allocation.
