Summary

This report addresses the challenge of public opposition to roundabouts in Montana, a phenomenon described as "roundabout anxiety" characterized by driver apprehension and concerns regarding safety and cost. Although roundabouts are recognized by the Federal Highway Administration as a proven safety countermeasure, the Montana Department of Transportation (MDT) faced significant resistance to proposed projects. The research aimed to synthesize effective public education and outreach strategies from other states and non-transportation sectors to help MDT promote roundabouts as a preferred intersection control method. The study employed a multi-faceted methodology including a comprehensive literature review of existing campaigns, an online survey and telephone interviews with transportation agencies nationwide, and a survey of Montana residents. The researchers analyzed agency experiences, public viewpoints, and various media materials such as websites, videos, brochures, and public service announcements. The goal was to identify successful approaches for engaging stakeholders and the general public during the planning and implementation phases of roundabout projects. Key findings revealed that 61 percent of surveyed Montanans opposed roundabouts, with only 14 percent believing improved education would change their views. However, 38 percent reported their opinions had shifted positively over time. Agency interviews indicated that no state engages in broad promotional media campaigns to "sell" roundabouts; instead, agencies focus on project-specific justification based on clear benefits. Successful outreach strategies identified in the literature and agency feedback include holding public meetings early in the design process, using visual aids like brochures and simulations, and tailoring messages to specific audiences. The review found that effective materials are uncomplicated, non-technical, and often utilize videos, radio PSAs, and dedicated websites to explain how to navigate roundabouts and highlight safety benefits. The significance of this synthesis lies in its practical recommendations for transportation agencies facing public skepticism. The report advises MDT to avoid generic promotional campaigns, which may appear biased, and instead focus on project-specific outreach that demonstrates why a roundabout is the optimal solution for a site. Recommendations include holding initial meetings with local officials, using town-hall style forums for public dialogue, and employing multimedia tools such as videos and print materials to educate drivers. By adopting these targeted, fact-based outreach strategies, agencies can build public acceptance, thereby facilitating the implementation of roundabouts to improve highway safety and traffic flow.

Key finding
