In addition, the lightweight plastic barriers will not damage expensive asphalt or concrete surfaces, and the interconnecting plastic channelizing units do not require an expensive end treatment (such as a crash cushion).
When plastic channelizing units are installed in a roadway work zone, workers tend to be more productive because they are not continually watching over their shoulder for drums or barricades that have been clipped by moving vehicles and thrown into the work zone.
When barriers are placed immediately adjacent to traffic, they should be equipped with appropriate channelizing devices, delineation, or other traffic-control devices.
Plastic channelizing units have a few additional benefits.
At the close of the event, there was a discussion of the findings of the event and a session to discuss improvements that could enhance existing longitudinal
channelizing barricades and ideas for developing new products.
