Achieving Transportation and Land Use Win-Win using Quadrant, U-Turn, and One-Way Intersections

When: July 8, 2025 | 2:00 -- 3:30 PM ET

This webinar is led by the ITE Traffic Engineering Council

Webinar Description:

High-speed suburban arterials are commonly lined with auto-oriented commercial development and frequently experience high traffic volumes. These types of corridors are often referred to as “Stroads”—a blend of “street” and “road”—as they attempt to fulfill the dual roles of moving large volumes of vehicles quickly while also serving as centers for local commerce and community activity.

Balancing these competing functions can be challenging. The result is often a built environment characterized by extensive hardscape and complex signal patterns, which can lead to slower travel speeds and limited pedestrian accessibility.

Fortunately, recent advancements in Alternative Intersection design offer promising solutions. Approaches such as Quadrant Intersections, One-Way Splits, and U-Turn–based configurations have shown potential to reduce congestion, enhance safety, and support walkable, more community-friendly environments—all without compromising vehicular efficiency.

In this 90-minute session (including Q&A), Chris Cunningham of NCSU’s Institute for Transportation Research and Education (ITRE) and Mike Brown of Urban Innovators will present findings from their recent NCDOT study, Urban Applications of Innovative Intersection Designs. The presentation features graphics-rich content focused on retrofitting major arterials for walkability and planning effective designs in developing areas. To prepare, visit UrbanInnovators.com, navigate to Projects > NCDOT, and access the full report, supporting materials, and interactive before/after visuals.

Learning Objectives:

• Explain how investing in walkable design can be more cost-effective than minimal infrastructure.
• Identify where Quadrant, One-Way, and U-Turn intersection designs can be applied.
• Understand the concept of “driving slower to travel faster” and its implications for traffic flow.
