Advantages of the Split Intersection, Public Roads Magazine, May/June 2000.
As urban and suburban intersections become more congested, a possible remedy to the recurring traffic jam is to separate the grades of the intersecting roads in the form of a diamond interchanges. A more economical intersection treatment is the split intersection. This treatment requires that the major road be separated into two one-way roads comparable to an at-grade diamond junction. The split intersection facilitates smoother traffic flows with less delay, and safety should be improved by reducing congestion and separating the opposing directions of traffic.
Research
Active Projects
Analysis and Assessments of Novel Intersection Treatments and Technologies
Research objective will be to study and report operational and safety performances of the median U-turn intersection treatment. The study will expand the sample of the speed reduction treatment study at rural TWSC intersections.

Research objectives are to: (1) conduct research and develop an informational guide that should provide as a minimum, selection procedures for treatment types, or suggestions for design and safety, operations, and pedestrian accommodations; and (2) develop marketing materials in the form of TechBriefs and traffic animation videos.
