Summary

This report, titled *Communication Plan for Windblown Dust* (SPR-723), addresses the safety hazards posed by windblown dust events in Arizona, particularly on Interstate 10 between Phoenix and Tucson. These events, which range from regional monsoonal storms to localized, unpredictable dust channels driven by cold fronts, contribute to serious crashes. The study was motivated by the need to improve the Arizona Department of Transportation’s (ADOT) ability to detect these events, communicate warnings effectively, and influence driver behavior to enhance road safety. The research team employed a multi-faceted methodology to assess current practices and identify gaps. They conducted a comprehensive literature review on visibility detection systems and driver behavior, reviewed historical crash data, and analyzed ADOT’s existing protocols, including the “Pull Aside, Stay Alive” campaign and a pilot dust monitoring system in the Safford District. The team also benchmarked practices against other U.S. transportation agencies. Crucially, they gathered primary data from Arizona travelers through a survey of 44,000 ADOT email subscribers and two focus groups. These data collection efforts evaluated drivers’ awareness of dust storms, their preferred sources for weather information, their driving behaviors during low-visibility events, and their perceptions of ADOT’s current outreach efforts. The findings revealed significant opportunities for improvement in detection, communication, and education. Regarding detection, the report noted that current meteorological models and optical sensors struggle with localized dust events, recommending pilot studies for alternative small-sensor technologies and the integration of human verification via CCTV. Communication analysis showed that younger drivers prefer online and social media tools, while nearly half of respondents relied on mobile applications. However, many drivers expressed confusion regarding specific safety instructions, such as turning off lights when pulling over. Additionally, the survey indicated that ADOT’s communications were not effectively reaching out-of-state drivers, a demographic heavily impacted by these routes. Based on these findings, the report provides a tiered set of recommendations for short-, mid-, and long-term implementation. Short-term actions include aggressively marketing existing digital tools and clarifying the rationale behind safety tips in the “Pull Aside, Stay Alive” campaign. Mid-term recommendations involve developing a dedicated ADOT mobile app, updating public service announcements to highlight the consequences of driving in dust, and deploying additional sensors. Long-term strategies include expanding dynamic message signs in dust “hot-spots” with instructional messaging and fostering partnerships with the National Weather Service and universities to improve meteorological modeling. The report concludes that while ADOT’s current efforts are robust compared to other states, targeted refinements in technology and messaging are essential to further reduce crash risks associated with windblown dust.

Key finding

Younger drivers prefer online and social media for weather information while older drivers rely on traditional media, and the 'Pull Aside, Stay Alive' campaign causes confusion regarding specific safety tips like turning off lights.
