Traffic Safety Analysis at Signalized Intersections During Work Zones Intervals by Using the LiDAR Sensor Technology

The importance of conflict analysis and safety considerations during work zone intervals at signalized intersections cannot be overstated, as these periods pose unique challenges and safety risks for … [Read more...] about Traffic Safety Analysis at Signalized Intersections During Work Zones Intervals by Using the LiDAR Sensor Technology

A Guide to Work Zone Temporary Traffic Control Near Signalized/Unsignalized Intersections

The objective of this document is to assist transportation engineers and traffic control professionals in improving their knowledge on safety and operations of work zones in the immediate vicinity of … [Read more...] about A Guide to Work Zone Temporary Traffic Control Near Signalized/Unsignalized Intersections

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

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

Rapid Response Techniques for Disasters Near Roadway Work Zones: Temporary Roundabouts

Work zone traffic management requires consideration of both normal conditions and potentialemergencies. The combination of a construction closure and an adverse event such as a severe … [Read more...] about Rapid Response Techniques for Disasters Near Roadway Work Zones: Temporary Roundabouts
