ADVANTAGES OF OFFSET T-INTERSECTIONS WITH GUIDELINES

Intersection safety constitutes one of the most critical elements of the highway system in the United States. About 23% of fatalities and 49% of highway injuries occur at intersections, both signalized and non-signalized. Single-vehicle crashes account for approximately 24% of the crashes at non-signalized rural T-intersections and 13% of the crashes at four-legged intersections (two-way stop-controlled). In urban areas, this difference is not noticeable (14% at T-intersections compared to 12% at four-legged intersections). This study focuses on improving safety and operational performances of four-legged crossings by offsetting them and creating two offset T-intersections.
