Summary
This report details Phase II of a Pacific Northwest Transportation Consortium (PacTrans) project aimed at mitigating lane departure crashes, which account for over half of U.S. traffic fatalities. The study addresses the need for public education regarding roadway safety by engaging high school and college students in the Pacific Northwest through a Public Service Announcement (PSA) competition. The objective was to generate creative safety materials while raising awareness among younger drivers about the risks associated with lane departures. The methodology involved executing a competition planned in Phase I, requiring participants to submit three components: a 20–30 second video, a series of five social media posts (Twitter or Instagram), and a poster. Entries were collected via a web-based portal and categorized by state for high school students and by participating university for college students. A total of 13 entries were received across nine competition categories. Project team members evaluated submissions based on creativity, originality, adherence to guidelines, and expression of the theme “Make Safety Your Focus.” Winners were selected for first, second, and third place in each category, receiving monetary prizes ranging from $250 to $750. The analysis of the 13 submissions revealed high-quality materials that demonstrated a creative understanding of the safety issue. A dominant theme across videos, social media posts, and posters was driver distraction, particularly the use of cell phones, as a primary cause of lane departure crashes. Other mentioned factors included eating, talking, and driving under the influence. However, the report notes that significant contributing factors identified in existing literature, such as speeding, fatigue, and adverse weather conditions, were largely absent from the student submissions. The low participation rate was attributed to ineffective marketing strategies, insufficient prize incentives relative to the workload, and technical issues with the submission portal’s file size limits. The significance of this project lies in its contribution to regional safety outreach and the generation of usable PSA materials for broader distribution via PacTrans communication channels. The findings highlight the effectiveness of student-led engagement in identifying key safety concerns like distraction, while also revealing gaps in public understanding regarding other crash contributors. Based on lessons learned from the low entry volume, Phase III of the project will expand the competition to include K-9 students and adjust outreach strategies to improve participation and further educate the public on roadway safety.
Key finding
Student-submitted public service announcements overwhelmingly identified driver distraction, specifically cell phone use, as the primary cause of lane departure crashes, despite the overall low participation rate in the competition.
