The Importance of Proven and Tested Positive Protection in Work Zones

The use of positive work zone protection is an issue of balancing the cost versus the level of safety offered. At times positive protection in work zones is not provided because the project is of short duration. Road authorities need to understand the characteristics of different barrier options in order to select the appropriate barrier type. Movable barriers offer advantages of increased productivity and a reduction in congestion when lanes can be opened for traffic in peak periods. They can be used to provide positive protection to a work zone. They can be used to provide a wider work zone for delivery of materials. They can be used to provide tidal flow on a carriageway when the opposing carriage way is being reconstructed. The paper concluded that movable barriers offer construction projects the following advantages: lanes management flexibility especially during peak periods to reduce congestion; more workspace during off-peak periods to utilize larger, more efficient equipment to accelerate completion; positive separation between workers and motorists; allows faster, safer completion of projects; long design life; barriers can then be used permanently as movable medians; more effective use and return on asset for road authorities; and increased road use flexibility.
