Traffic Conflicts in the Lane-Switching Sections at Highway Reconstruction Zones
Introduction: There are designated sections for lane-shifting in several highway reconstruction and expansion zones. Similar to the bottleneck sections of highways, these sections are characterized by … [Read more...] about Traffic Conflicts in the Lane-Switching Sections at Highway Reconstruction Zones
Variable Speed Limit Control of Traffic Flow in Expressway Construction Zone
With the increasing speed of construction and the continuous improvement of its corresponding infrastructure, the expressway plays an increasingly important role in promoting the development of … [Read more...] about Variable Speed Limit Control of Traffic Flow in Expressway Construction Zone
Methodology for Monitoring Work Zones Traffic Operations Using Connected Vehicle Data
The National Work Zone Safety Information Clearinghouse estimated there were approximately 115,000 work zone crashes with 842 fatalities in 2019. There is broad consensus that it is important for … [Read more...] about Methodology for Monitoring Work Zones Traffic Operations Using Connected Vehicle Data
Saturation Flow Rate at the Work Zone–Straddled Intersections With Interweaving Movements: Lane-Based Modeling Study
This study explored how the presence of work zones could influence the saturation flow rate (SFR) prevailing at an intersection. Specifically, it researched construction-ridden intersections with … [Read more...] about Saturation Flow Rate at the Work Zone–Straddled Intersections With Interweaving Movements: Lane-Based Modeling Study
Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation
This project addressed the following: 1) a lack of a system to process raw traffic footage obtained from work zones to extract traffic and driver behavior information, especially systems that leverage … [Read more...] about Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation
