Temporary work zones (TWZs) have become the second largest contributor to the non-recurring delay of U.S. highways, causing nearly 24 % of all non-recurring delay and 10 % of overall delay. Efficient … [Read more...] about Evaluating the Effectiveness of Traffic Diversion and Managed Lanes on Highway Work Zones

Variable Speed Limit Control for Severe Non-Recurrent Freeway Bottlenecks
Variable speed limit (VSL) schemes are developed based on the Kinematic Wave theory to increase discharge rates at severe freeway bottlenecks induced by non-recurrent road events such as incidents or … [Read more...] about Variable Speed Limit Control for Severe Non-Recurrent Freeway Bottlenecks
Analysis, Modeling, and Simulation for Traffic Incident Management Applications
Traffic incidents are a major source of congestion in both urban and rural areas. Nationally, roughly 25% of total congestion is due to traffic incidents. Further, traffic incidents create unexpected … [Read more...] about Analysis, Modeling, and Simulation for Traffic Incident Management Applications
Fuel Conservation Through Freeway Work Zone Traffic Diversion Planning
Construction activities and numbers of related work zones on urban freeways have grown significantly. The most problematic work zones occur on roads that are already fully loaded, and impacts of work … [Read more...] about Fuel Conservation Through Freeway Work Zone Traffic Diversion Planning
Determining Road User Costs for Work Zone Construction Sequencing Using Multiresolution Modeling Methods
Traffic congestion has continued to increase over the past decade. As a result, there has been an increase in roadway construction throughout the United States. However, work zones contribute to … [Read more...] about Determining Road User Costs for Work Zone Construction Sequencing Using Multiresolution Modeling Methods
Utilization of Remote Traffic Monitoring Devices for Urban Freeway Work Zone Assessment
The two primary objectives of this project were to assess urban freeway work-zone impacts through use of remote monitoring devices, such as radar-based traffic sensors, traffic cameras, and traffic … [Read more...] about Utilization of Remote Traffic Monitoring Devices for Urban Freeway Work Zone Assessment
