Simulation of Roadside LiDAR Applications: A Smart Work Zone Case Study
Light detection and ranging (LiDAR) have the capability to detect 360-degree surrounding objects with high accuracy (centimeter level), high frequency (a tenth of a second), and long measuring … [Read more...] about Simulation of Roadside LiDAR Applications: A Smart Work Zone Case Study
Calibration and Validation of a Microsimulation Model of Lane Closures on a Two-Lane Highway Work Zone
Lane closure on a two-lane work zone can negatively affect operational performance. Although a microsimulation model is often used to quantify and predict these negative impacts, it requires proper … [Read more...] about Calibration and Validation of a Microsimulation Model of Lane Closures on a Two-Lane Highway Work Zone
Automated Vehicle Detection Systems Data as a Promising Approach for Roadway Construction Planning: The Case of Dallas, Texas, Highway System
Construction activities on roadway infrastructure have adverse impacts on traffic safety and mobility because of often needed lane and shoulder closures. Existing approaches for planning roadway … [Read more...] about Automated Vehicle Detection Systems Data as a Promising Approach for Roadway Construction Planning: The Case of Dallas, Texas, Highway System
Assessment of Driver Distraction at Work Zones With Portable Rumble Strip Deployments in Texas
The objective of this research was to assess the extent of distracted driving occurring on roadways in Texas, U.S., as drivers approach a work zone and the extent to which portable rumble strips (PRS) … [Read more...] about Assessment of Driver Distraction at Work Zones With Portable Rumble Strip Deployments in Texas
Characterization, Detection, and Segmentation of Work-Zone Scenes From Naturalistic Driving Data
This paper elucidates the automatic detection and analysis of work zones (construction zones) in naturalistic roadway images. An underlying motivation is to identify locations that may pose a … [Read more...] about Characterization, Detection, and Segmentation of Work-Zone Scenes From Naturalistic Driving Data
