Summary
This paper addresses the critical need for improved safety training for roadway construction workers, who face significant risks in work zones. In the United States, 20% of the roadway system is under construction, with 108 worker fatalities reported in 2021 alone; nearly half of these involved workers struck by vehicles. Traditional training methods are often limited by high costs, fixed schedules, and the inability to provide risk-free practice environments. To address these drawbacks, the researchers developed an immersive Virtual Reality (VR) training platform designed to enhance workforce education through practical, simulated on-the-job training. The study utilized state-of-the-art VR technologies, specifically the Meta Quest Pro headset and the Unity3D engine, to create a platform comprising an immersive module and an assessment module. The system allows trainees to perceive virtual work zone scenarios and interact with objects, facilitating a "learn by doing" approach. The researchers coded flagger operations for a rural two-lane work zone, developing four training scenarios that instruct users on basic skills such as stopping, releasing, and slowing traffic. The assessment module tracks user performance at predefined checkpoints and provides real-time feedback. An internal test was conducted with nine volunteers lacking prior work zone experience. Participants underwent either VR or traditional training, followed by a field test and a post-training survey to evaluate effectiveness and gather feedback. The results indicated that VR training is an effective solution for enhancing work zone safety skills. The VR training demonstrated an effectiveness rate of 89%, compared to 82% for traditional training methods. Participants reported increased confidence and effectively acquired essential knowledge and skills related to flagger operations. The comparison of performance before and after VR training showed significant skill enhancement. However, the study also identified limitations in the current platform, including issues with hand tracking, virtual paddle operations, the simulation of speeding vehicles, and user interface design. Participants requested more immersive experiences, explicit instructions, and straightforward operations. The significance of this research lies in demonstrating that VR training can serve as a valuable supplemental module integrated into existing work zone training programs. It offers a scalable solution that allows trainees to practice skills in various high-risk scenarios without spatial or temporal constraints. The findings suggest that VR can deliver performance comparable to or surpassing traditional in-person methods. Based on participant feedback, the research team plans to improve the platform’s technical aspects and expand its applications to include urban work zones, work zone inspections, Road Safety Audits (RSA), and railway operations. This approach supports the broader goal of ensuring safety and equality in the transportation workforce through innovative educational tools.
