In addition, the research project examined how workspace access points contribute to the CMV crash risk in work zones. In Phase 1, the research team reviewed previous research findings, conducted a preliminary crash analysis, and identified potential projects and novel data sources. In Phase 2, the research team reviewed the characteristics, narratives, and diagrams of fatal, serious injury suspected, and minor injury suspected CMV-involved work zone crashes to determine the factor that primarily influenced the crash, whether a CMV was fault, and whether a work-related CMV was involved. In addition, the research team used two statistical modeling techniques to identify the association between critical factors. The research team also conducted field studies in Phase 2 to observe the operational and safety impact of workspace access points. Based on the crash analysis and field study findings, the research team made 10 recommendations for improving CMV safety in work zones
