Work Near Signalized and Unsignalized Intersections
Intersections traditionally represent an area of safety concern given conflicting movements that increase the frequency and severity of traffic crashes as compared to other road locations. This issue … [Read more...] about Work Near Signalized and Unsignalized Intersections
Revealing the Impact of Mainstream Disruptions on On-Ramp Merging Behavior—A Virtual Reality (VR) Approach Using Work Zone Case Studies
Infrastructure disruptions such as lane closures present traffic efficiency and road safety challenges, especially on freeways. Such impacts become more significant when combined with compulsory … [Read more...] about Revealing the Impact of Mainstream Disruptions on On-Ramp Merging Behavior—A Virtual Reality (VR) Approach Using Work Zone Case Studies
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
