Merging Area

Behavior Study of Merge Practices for Drivers at Work Zone Closures

The purpose of this project was to determine which driver behaviors result in the greatest reduction of capacity with work zone lane closures. Traffic and safety experts believe that driver behaviors, … [Read more...] about Behavior Study of Merge Practices for Drivers at Work Zone Closures

Joint Merge and Its Impact on Merging Speeds in Lane Reduction Areas of Construction Zone

To increase the efficiency and safety of traffic flow in the vicinity of lane reduction transition areas, engineers have begun to use innovative techniques to facilitate traffic flow through these … [Read more...] about Joint Merge and Its Impact on Merging Speeds in Lane Reduction Areas of Construction Zone

Don’t Feel Cheated: ‘Late Mergers’ in Construction Zones can Actually Ease Traffic Congestion

Most drivers believe they are abiding by proper roadway etiquette when they merge as soon as possible after being notified of a lane closure. Because most drivers merge early, an open lane is created … [Read more...] about Don’t Feel Cheated: ‘Late Mergers’ in Construction Zones can Actually Ease Traffic Congestion

This research examined the safety and operational benefits of having traffic merge early into the open lane prior to a work zone merge area. A 2007 law in Oklahoma adopted the use of additional “STATE … [Read more...] about Evaluation of Early Merge Static Work Zone Signing in Oklahoma

Work Zone Simulation Model: Companion Report for “Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones”

To support the analysis of driver behavior at rural freeway work zone lane closure merge points, CTRE staff collected traffic data at merge areas using video image processing technologies. The … [Read more...] about Work Zone Simulation Model: Companion Report for “Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones”

Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones

Applying better management practices requires knowledge of the traffic flow properties and driver behavior in and around work zones, and knowledge of possible management strategies. The project … [Read more...] about Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones
