This is an accepted article with a DOI pre-assigned that is not yet published.This study aims to compare crashes caused by a variety of factors for roundabouts versus traditional intersections across income levels in Michigan’s Southeast counties from 2019 to 2023. The analysis reveals that roundabouts in low-income communities experience higher overall crash rates but lower rates of behavioral crashes like speeding and alcohol involvement. This pattern reverses trends seen at traditional intersections, where low-income communities typically fare worse across crashes caused by all categories. These findings exemplify how roundabouts' self-enforcing design may reduce behavior-related crash types in low-income communities, though operational challenges lead to higher rates of minor crashes.
