Summary

This study addresses the economic impact of Restricted Crossing U-Turn (RCUT) intersections, also known as J-turns, on local businesses in Louisiana. While RCUTs are recognized by the Federal Highway Administration as a "Proven Safety Countermeasure" that significantly reduces severe injury crashes, their implementation often faces resistance from nearby business owners who fear reduced customer access and subsequent sales declines. The research aims to quantify these economic effects and assess stakeholder perceptions to inform future access management strategies. The methodology involved analyzing sales tax data from the Louisiana Department of Revenue for ten completed J-turn projects across four parishes: East Baton Rouge, Lafayette, St. Tammany, and Jefferson. The study compared sales performance for a two-year period before and a two-year period after the construction of each intersection. Additionally, the researchers conducted surveys of businesses and patrons at these locations to gauge perceptions of access, congestion, and traffic safety. The analysis included aggregate sales data, parish-specific breakdowns, and specific examinations of volatile industries like gas stations and restaurants. The findings indicate that the construction of J-turns is associated with an overall increase in sales for businesses in their vicinity. Aggregate analysis showed no evidence of a statewide sales decline; rather, sales increased post-construction. Parish-by-parish analysis confirmed this trend, with one exception in a rapidly growing parish where some existing businesses saw slight declines. However, the overall sales volume in that parish still increased, and the isolated declines were attributed to increased competition from new businesses rather than the intersection design itself. Survey results revealed that public concerns about access were primarily driven by perceptions of congestion, traffic backups, and ongoing construction impacts, rather than actual difficulty in reaching businesses. The significance of this research lies in its ability to counteract misconceptions regarding the economic viability of RCUTs. By demonstrating that J-turns do not negatively impact business sales and often correlate with increased revenue, the study provides evidence-based support for their continued deployment. The findings suggest that transportation agencies should focus public outreach on addressing concerns about congestion and construction impacts rather than access limitations. This supports the Louisiana Department of Transportation and Development’s goal of implementing proven safety countermeasures to reduce fatalities and serious injuries while maintaining economic stability for local businesses.

Key finding

Sales data analysis showed an overall increase in sales for businesses surrounding J-turn projects, with no evidence of a general decline in parish-level sales.
