CARMA: Improving Traffic Flows and Safety at Active Work Zones

Federal Highway Administration’s CARMA^SM Program is leading research on the information exchanges and cooperative maneuvers that constitute cooperative driving automation (CDA).  The work zone management (WZM) use case is part of the CARMA Reliability research track. This research track examines solutions to nonrecurring congestion on freeways and arterials, such as traffic incidents and inclement weather, in addition to work zone activity. The WZM use case establishes the framework of using CDA features in active work zone areas to ease congestion and enhance traveler and worker safety.
