Lessons Learned
This benefit was Benefit of the Month for March, 2007! In North Carolina, a modeling study indicated that work zone delay messages reduced maximum traffic backups by 56 percent and contributed to 55 percent reduction in traveler delay.
11-15 January 2004. Summary Information In this study, the QuickZone traffic analysis tool was used to compare traffic conditions with and without the provision of real-time work zone traffic information at a representative two-mile work zone on I-95 in North Carolina. The system evaluated was designed to monitor traffic conditions in real-time, determine expected traffic delays, and advise motorists of current delays and alternate route information using portable dynamic message signs (DMS) and an Internet Web site. The goal was to reduce demand in the work zone during periods of heavy congestion.
The rehabilitation project covered a 19-mile section of I-95 and included multiple work areas. The design and size of each active work area was dependent on the location of detour routes, and need for lane closures and traffic controls. The segment of the work zone selected for analysis in this study was located between Milepost 150 and Milepost 154, and was about two miles long. Application Areas
