  • Abstract:
    Work zones cause congestion, and result in more than 800 fatalities and 37,000 injuries in the U.S. every year. However, as our infrastructure ages, there is an increasing need for the maintenance and rehabilitation of our roadways, which means more work zones. Forward-looking transportation agencies across the country are using Intelligent Transportation Systems (ITS) in their major work zones to make travel through and around the work zones safer and more efficient. The purpose of this document is to raise awareness among maintenance and construction engineers and managers of the applications and benefits of ITS in work zones. ITS technology can be applied in work zones for: traffic monitoring and management, providing traveler information, incident management, enhancing safety of both the road user and worker, increasing capacity, enforcement, tracking and evaluation of contract incentives/disincentives (performance-based contracting), and work zone planning. This report documents the findings from site visits to work zones utilizing ITS.
