Intrusion Alert Technologies for Safer Workzones

 

This study evaluated the effectiveness and implications of four workzone intrusion alert technologies, with a focus on drivers’ and workers’ cognition, their perception of alerts, and their corresponding responses. The research not only examined how these intrusion technologies could reduce intrusions and alerting workers but also explored the psychological and behavioral impacts on those in the work zone environment. The findings of this study provided valuable insights that were used to develop practical guidelines for implementing these technologies. Additionally, a decision-making tool was created to help the Indiana Department of Transportation (INDOT) and contractors make informed choices when selecting the most suitable technology for specific work zones. This research offers a significant step toward enhancing work zone safety and reducing the number of crashes."
