ITS-based lane management technologies were introduced to work zones in an attempt to reduce congestions and diminish queue lengths. Two forms of lane merging namely the early merge and the late merge … [Read more...] about Two Simplified Dynamic Lane Merging System (SDLMS) for Short Term Work Zones
Merging Control
Evaluation of Work Zone Design Features to Aid Older Drivers
Work zones are estimated to account for 22 percent of roadway crashes and more than 1000 fatalities annually. Moreover, older road users have been overrepresented in work zone crashes. In an effort to … [Read more...] about Evaluation of Work Zone Design Features to Aid Older Drivers
Integrated Work Zone Safety Management System and Analysis Tools
In Florida, despite recent efforts to improve work zone safety, the number of crashes and fatalities at work zones has increased continuously over several past years. For addressing the existing … [Read more...] about Integrated Work Zone Safety Management System and Analysis Tools
Lane-Based Dynamic Merge Control Strategy Based on Optimal Thresholds for Highway Work Zone Operations
Despite the potential effectiveness of the dynamic late merge (DLM) control, most existing DLM systems, based on static thresholds, cannot best perform under time-varying traffic conditions. This … [Read more...] about Lane-Based Dynamic Merge Control Strategy Based on Optimal Thresholds for Highway Work Zone Operations
Effectiveness of Dynamic Messaging on Driver Behavior for Late Merge Lane Road Closures
Efforts to improve safety and traffic flow through merge areas on high volume/high speed roadways have included early merge and late merge concepts and several studies of the effectiveness of these … [Read more...] about Effectiveness of Dynamic Messaging on Driver Behavior for Late Merge Lane Road Closures
Traffic Control Strategies for Congested Freeways and Work Zones
The primary objective of the research was to identify and evaluate effective ways of improving traffic operations and safety on congested freeways. There was particular interest in finding … [Read more...] about Traffic Control Strategies for Congested Freeways and Work Zones
