Urban Applications of Innovative Intersection Designs

The primary objective is to discover the pros and cons of Alternative Intersections (AIs) in urban settings, and communicate both the good and bad effectively to North Carolina Department of Transportation (NCDOT) and subsequent stakeholders. The effort will result in highly detailed 2D/3D graphical depictions of corridors with AI designs such as Quadrants, Bowties, Thru-Turns, RCUTs, MUTs, and One-Way Split Intersections, accentuating their full “place-making” potential. The research team will compare them to each other not only visually, but also numerically in terms of overall footprint, traffic level of service (LOS) performance, maximum 1-hour entering capacity, expected speed and safety effects, and expected cost ranges. The research will also attempt to depict more traditional corridor designs, such as “double-left” intersection designs, both as they typically exist now, and as they might exist with “equally ambitious” place-making features, so the overall footprint and acreage of space dedicated to pavement vs non-pavement uses can be compared “apples to apples.”
