Summary
This report documents Phase 2 of a project aimed at addressing gaps in transportation safety education for the Pacific Northwest. The research was motivated by the high collision rates in the United States and the lack of standardized, transferable training materials for both transportation practitioners and academicians. While safety data collection has expanded, many local agencies and universities lack the resources to effectively manage and analyze this data. The project’s primary objectives were to refine introductory curriculum materials for practitioners and academicians, and to investigate crash reporting methodologies in remote areas to improve data comprehensiveness. The study employed a mixed-methods approach involving three distinct components. First, practitioner-developed training tools, consisting of PowerPoint slide decks, were pilot-tested with seven transportation agencies in Idaho and Oregon. Researchers conducted semi-structured phone interviews with agency directors and supervisors to evaluate the content, format, and usability of the materials. Qualitative data were analyzed using coding software (Dedoose) to identify themes such as usefulness, formatting, and recommendations. Second, academic training tools were reviewed by 18 faculty members from institutions across the country who teach transportation or safety-related courses. These faculty members assessed the potential classroom effectiveness of the materials. Third, the team conducted a case study on crash reporting in remote Alaska, comparing three data sources: the standard state crash reporting system (ADOT&PF), the state-mandated Trauma Registry, and local newspaper reports from three communities. The findings revealed that practitioner feedback was largely positive regarding the format and content of the training slides, with most participants finding them easy to follow and useful for sharing within their agencies. However, respondents suggested breaking the presentations into smaller segments to avoid overwhelming new engineers and recommended adding indices and specific "takeaway" actions. Consequently, the original three slide decks were restructured into five shorter, more focused presentations. The academic review confirmed the value of the materials for classroom integration. In the remote area case study, the research found that official state databases and trauma registries frequently missed crashes involving off-road vehicles, such as ATVs and snowmachines. Newspaper reports from small, non-highway communities provided a more comprehensive record of these incidents than official agency databases, highlighting significant underreporting in standard systems. The significance of this work lies in its contribution to workforce development and data integrity in transportation safety. By refining and validating educational tools, the project provides accessible resources to improve the safety culture and analytical capabilities of local transportation agencies. Furthermore, the findings regarding remote crash reporting suggest that relying solely on official databases may lead to incomplete safety assessments in rural areas. The study implies that integrating local, non-standard data sources, such as newspaper reports, can offer a more accurate picture of crash frequencies and types in remote regions, thereby supporting better-targeted safety investments and decision-making.
Key finding
Reliance on local sources, such as town newspapers, provides a more comprehensive assessment of crash occurrences in remote areas than existing trauma registries and official crash databases.
