Safety Evaluation of J-turn Intersections in Missouri

The project objective is to investigate the safety effectiveness of J-turn intersections in Missouri. The research methodology to meet this objective includes study design, data collection and analysis, and a review of existing literature. Attainment of the project objective will lead to greater understanding of the safety benefits of J-turns and the effect of site characteristics (e.g., geometrics, traffic volume) on crash frequency and severity.
