Summary
This 1985 report by Jessica A. Ginsburg addresses the challenge of establishing legislative priorities for transportation safety in Virginia. Because transportation safety involves multiple agencies and jurisdictions, unilateral policy determination by the Department of Motor Vehicles (DMV) was deemed inappropriate. The study aimed to generate a consensus-based legislative package for the 1986 General Assembly session by leveraging the expertise of a diverse panel representing law enforcement, health, education, and judicial sectors. To overcome the limitations of traditional committee approaches—such as dominant individual influence and social conformity pressures—the study employed a modified Delphi technique. This method combined the anonymous, iterative feedback of the classic Delphi process with the structured individual ranking of the nominal group technique and the clarifying discussion of interactive group sessions. The methodology involved three distinct phases. First, an initial list of 39 legislative proposals was compiled from previous research and bills, then expanded through a solicitation of suggestions from over 500 state and local officials. Second, a panel of 16 experts completed a mail questionnaire ranking proposals based on magnitude, feasibility, and impact, and selecting their top ten priorities. These results were aggregated and provided as feedback to the panel. Third, during a one-day face-to-face session, panelists reviewed the feedback, engaged in structured discussion, and conducted two additional rounds of anonymous ranking. This iterative process allowed for the refinement of proposals, the grouping of related measures into packages, and the integration of late additions suggested during the meeting. The process resulted in a final list of 13 prioritized legislative recommendations. The highest-ranked proposal was mandatory seat belt use, which received the highest scores for magnitude and impact and was selected as a top priority by all panelists in the final round. Lowering the per se blood alcohol concentration (BAC) violation level from 0.15% to 0.10% was the second-highest priority. Other key recommendations included extending child restraint requirements to all drivers, creating a revocation package to facilitate license confiscation, eliminating the two-hour arrest window for DUI, and prohibiting drinking while driving. The panel also prioritized legal immunity for Crash Investigation Teams, increased penalties for hit-and-run offenses, authorization of aerial speed enforcement, prohibition of altered suspensions on pickup trucks, extending mandatory alcohol safety program participation to one year, restricting tinted glass, and allowing refusal to take alcohol tests as admissible evidence. The significance of this study lies in its demonstration of a hybrid methodology that effectively generates group consensus on complex, multidisciplinary issues. By combining individual critical evaluation with face-to-face clarification, the modified Delphi technique mitigated the biases inherent in traditional committee deliberations while maintaining the efficiency required for legislative planning. The report concludes that this approach successfully produced a unified legislative agenda supported by diverse stakeholders, offering a replicable model for other agencies facing similar coordination challenges.
Key finding
The expert panel prioritized mandatory seat belt laws and lowering the per se blood alcohol concentration violation to 0.10% as the top two legislative priorities for Virginia transportation safety.
