Abstract:

This report represents a technology supplement to the 2014 Work Zone Intelligent Transportation Systems (WZITS) Implementation Guide (Report No. FHWA-HOP-14-008). The Guide forms the foundational framework, concepts, and methods for establishing a WZITS program. The Guide further introduces various Intelligent Transportation Systems (ITS) technology solutions, but does not go into details on their functionality or standard specifications. The purpose of this document is to supplement the original Guide with this information, and includes factsheets and specification sheets for nine WZITS technologies. The technologies are Dynamic Lane Merge, Queue Warning, Variable Speed Limit, Automated Enforcement,
Entering/Exiting Construction Vehicle Notification, Temporary Ramp Metering, Real-Time Traveler Information, Incident Management System, and Performance Measurement.
