Roundabouts, J-Turn, etc. - Understanding their Economic Impacts

This research aims to investigate the economic impact and benefits of J-Turn intersections and roundabout treatments on Minnesota roads. While these treatments are increasingly preferred for their operational and safety advantages, they often face resistance from community residents and nearby businesses. The study's primary focus is to demonstrate the economic benefits of J-Turns and roundabouts to the public, local businesses, and the community as a whole. The research will employ a multi-stage approach to comprehensively assess these benefits. In the initial stage, interviews with business owners will be conducted to gauge their sentiments regarding roundabouts and their effects on business performance. Subsequently, the study will analyze traffic counts (AADT) on roads leading to roundabouts and J-Turn treatments before and after installation to determine any changes in traffic flow. Finally, an economic impact assessment will be conducted by analyzing sales tax data for census tracts near these treatments. Perceived economic benefits will also be calculated by examining reductions in fatal and injury crashes due to the treatments.
