Summary
This study addresses the critical safety challenges in highway construction and maintenance work zones, where vehicle intrusions by distracted drivers cause significant fatalities and injuries. While intrusion alert technologies are increasingly adopted to warn drivers and workers, existing research lacks comprehensive evidence regarding their effectiveness, user acceptance, and cost-efficiency. The Indiana Department of Transportation (INDOT) lacked standardized guidelines for selecting these technologies. Consequently, this research aimed to evaluate four commercially available intrusion alert systems—AWARE, SonoBlaster, Traffic Guard Worker Alert System (WAS), and Intellicone—to determine their efficacy in alerting drivers and workers and to develop a decision-making tool for optimal technology selection. The researchers employed a multi-phase methodology involving a comprehensive literature review, preliminary functional testing, pilot-controlled field testing, and physiological assessments of user responses. Preliminary tests evaluated technical specifications such as sound levels, alarm duration, and transmission ranges. Pilot testing assessed deployment ease and operational reliability in simulated work zones. To measure human response, the study utilized eye-tracking, electrodermal response (EDR), and hemodynamic monitoring to analyze drivers’ visual attention, cognitive load, and risk perception. Similarly, workers’ physiological responses and behavioral reactions were monitored during active work zone simulations. Additionally, the team conducted surveys with transportation professionals and contractors to gather qualitative feedback on usability and acceptance. The findings revealed that no single technology was universally effective for all safety concerns. Physiological measurements indicated that existing alert systems often failed to instill a sufficient sense of urgency in drivers, with auditory signals lacking distinctiveness. For instance, distinguishing sounds between devices like SonoBlaster and AWARE proved challenging. Among workers, despite recognizing alerts, many continued their tasks rather than evacuating, highlighting a need for improved training and system refinement. The study also identified operational challenges, including false alarms and complex setup procedures for certain systems. Based on these results, the researchers developed a metric-based decision-making framework incorporating evaluation criteria, weighting factors from INDOT professionals, and benefit-cost analysis to guide technology selection. The significance of this work lies in its provision of empirical evidence and practical guidelines for enhancing work zone safety. By identifying the limitations of current technologies and offering a structured decision-making tool, the study assists INDOT and other transportation agencies in selecting the most appropriate intrusion alert systems. The findings underscore the need for innovative designs with distinctive auditory signals and improved worker training protocols. Ultimately, the research aims to reduce work zone incidents and fatalities in Indiana and nationwide by promoting the effective deployment of advanced safety technologies.
Key finding
No single intrusion alert technology was universally effective for all work zone safety concerns, and existing systems were largely ineffective at instilling a sense of urgency in drivers or prompting workers to evacuate.
