Impact of HMI on Driver Behavior and Safety in Rural Work Zones: A Naturalistic Driving Approach
With the rapid development of vehicle-to-everything technology, human–machine interaction (HMI) systems are increasingly used in driving. This study investigates the impact of HMI technology on … [Read more...] about Impact of HMI on Driver Behavior and Safety in Rural Work Zones: A Naturalistic Driving Approach
A Safety Alarm Device for Protecting Road Workers
At present, the personal safety of road workers mainly relies on placing warning objects such as traffic safety cones and tripods on the road to remind rear drivers to avoid hitting the road workers. … [Read more...] about A Safety Alarm Device for Protecting Road Workers
Historical Prediction Attention Mechanism Based Trajectory Forecasting for Proactive Work Zone Safety in a Digital Twin Environment
Proactive safety systems aim to mitigate risks by anticipating potential conflicts between vehicles and enabling early intervention to prevent work zone-related crashes. This study presents an … [Read more...] about Historical Prediction Attention Mechanism Based Trajectory Forecasting for Proactive Work Zone Safety in a Digital Twin Environment
Audible Alert and TMA Lighting
Truck Mounted Attenuators (TMAs) are designed to mitigate crash severity. Currently, TMA drivers rely on visual checks via driving mirrors to manually trigger warnings thus placing the duty on … [Read more...] about Audible Alert and TMA Lighting
Assessing Workers’ Neuro-physiological Stress Responses to Augmented Reality Safety Warnings in Immersive Virtual Roadway Work Zones
This paper presents a multi-stage experimental framework that integrates immersive Virtual Reality (VR) simulations, wearable sensors, and advanced signal processing to investigate construction … [Read more...] about Assessing Workers’ Neuro-physiological Stress Responses to Augmented Reality Safety Warnings in Immersive Virtual Roadway Work Zones
