Summary

This study addresses the growing safety concerns associated with digital advertising billboards, which are designed to capture driver attention and potentially distract from the driving task. As technology evolves, regulations have struggled to keep pace with changes in sign illumination, motion, and content. The research aimed to quantify the degree of driver distraction caused by both typical and digital billboards and assess the resulting safety impacts, providing evidence to support updated regulatory frameworks. The methodology employed a comprehensive approach comprising a state-of-the-practice review, a crash investigation, and an on-road human factors evaluation. Researchers identified all digital billboards in Texas to inform site selection. The human factors study was conducted in Amarillo, Arlington, Killeen, and San Antonio, involving 85 participants who drove instrumented vehicles while their eye-gazing behavior was monitored. This data determined the frequency and duration of glances at various sign types. Additionally, the team evaluated nighttime lighting levels of both digital and standard billboards and collected participant feedback via closeout surveys. The findings revealed that digital billboards attract more frequent and longer glances than standard billboards, posing potential adverse traffic safety effects given that looking away from the roadway increases crash risk. Sign proximity and environmental complexity significantly influenced attention; signs closer to the road and those in less visually complex environments drew more looks. While the safety evaluation noted minor impacts on crashes, no statistically significant crash impacts were observed. Regarding illumination, digital billboards were generally brighter than standard illuminated ones, with on-premise digital signs often exhibiting excessive brightness compared to off-premise ones. This brightness raised concerns about glare, particularly for older drivers, potentially obscuring critical warning and guide signs. Participant surveys confirmed that sign brightness was a notable concern. The significance of this research lies in its provision of empirical data to guide the regulation of digital billboards. The study highlights the need for updated regulations to minimize negative safety impacts, specifically addressing issues like excessive brightness and the conversion of standard signs to digital formats. The authors recommend that agencies use these findings to improve regulations for both standard and digital billboards, thereby creating a safer driving environment. Furthermore, the study identifies a need for additional research and regulatory focus on digital on-premise signage to further mitigate distraction risks.

Key finding

Digital billboards attract more frequent and longer driver glances than standard billboards, though this increased distraction did not result in statistically significant crash impacts in the study.
