Driving Risks Assessment and In-Vehicle Warning Design for Improving Work Zone Safety
Work zones present unique risks to both workers and road users due to its complex and dynamic nature. This study developed a two-stage in-vehicle warning system aimed at refining driver behavior when … [Read more...] about Driving Risks Assessment and In-Vehicle Warning Design for Improving Work Zone Safety
Impact of an In-Vehicle Audio Prompt on Multistage Lane-Changing Behavior and Gaze Patterns in Work Zone
Introduction: Lane changing poses a great threat to traffic safety in the work zone areas. This study aims to conduct an in-depth investigation of drivers’ lane-changing behavior and to propose and … [Read more...] about Impact of an In-Vehicle Audio Prompt on Multistage Lane-Changing Behavior and Gaze Patterns in Work Zone
DROPS: A Drone-based Cyber-Physical-Human System for Workers’ Safety in Road Construction Sites
This work presents the design of DROPS (Drone-based Roadwork Operators Protection System), a drone-base Cyber-Physical-Human System for enhancing road construction site workers’ safety, integrating … [Read more...] about DROPS: A Drone-based Cyber-Physical-Human System for Workers’ Safety in Road Construction Sites
Principal Attributes of Wearable Warning Alarms to Promote Roadway Worker Safety
In response to a concerning increase in annual worker fatalities within U.S. roadway work zones and a lack of effective worker-centered alert systems in current practice, this study investigates how … [Read more...] about Principal Attributes of Wearable Warning Alarms to Promote Roadway Worker Safety
Estimating Safety Benefit of In-Vehicle Work Zone Safety Technology Alerts: A Counterfactual Monte-Carlo Simulation Approach
Work Zone Safety Technologies (WSTs) have exhibited great potential to improve road work zone safety by detecting safety risks and providing warnings to drivers and workers involved. Yet, it remains … [Read more...] about Estimating Safety Benefit of In-Vehicle Work Zone Safety Technology Alerts: A Counterfactual Monte-Carlo Simulation Approach
