Real-Time Work Zone Management for Throughput Maximization
A simple control concept is proposed for efficient real-time work zone management in cases where the arriving flow exceeds the capacity of the work zone, leading to congestion and reduced efficiency … [Read more...] about Real-Time Work Zone Management for Throughput Maximization
Simulation Trials on an Unconventional Alternative to Congestion Mitigation and Traffic Control at Highway Work-Zone Bottlenecks using Advanced Technologies
This paper presents a method to integrate the Dynamic Late Merge with a merge metering via wireless communication at the downstream taper area of a work zone, termed as Dynamic Merge Metering Traffic … [Read more...] about Simulation Trials on an Unconventional Alternative to Congestion Mitigation and Traffic Control at Highway Work-Zone Bottlenecks using Advanced Technologies
Two Simplified Dynamic Lane Merging System (SDLMS) for Short Term Work Zones
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
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
