Foreword

This report is part of a series of Federal Highway Administration (FHWA) products that examines the use of Intelligent Transportation Systems (ITS) in work zones. This document provides a summary of the findings of a national FHWA study to quantify the benefits of ITS applications for work zone traffic management. A summary report of this study was published in April 2008 (Report No. FHWA-HOP-08-021). More information on applications of ITS in work zones is available in other documents published earlier, including Intelligent Transportation Systems in Work Zones—A Cross-Cutting Study (Report No. FHWA-OP-02-025) and four case studies. All of these documents are available at http://www.ops.fhwa.dot.gov/wz/its/index.htm.

The April 2008 summary report of this study and the earlier reports were also published in hardcopy.
