What is a Reduced Conflict Intersection (RCI)?

As urban areas grow and traffic congestion increases, the N.C. Department of Transportation continues to look for creative solutions for improving mobility and safety. Corridors with growing traffic volumes and high crash rates are good candidates for a Reduced Conflict Intersection (RCI).

A Reduced Conflict Intersection is a general term used to describe several types of designs that may be used to improve safety and traffic flow on a highway. While there are variations to the designs, they all function the same at reducing conflicts for drivers and pedestrians - hence the term Reduced Conflict Intersection.

With the most common type of RCI design, drivers on the main road follow their usual paths, but raised medians redirect drivers from the side road into turning right. When there is a safe opening in traffic, drivers turn right to easily enter the flow of traffic on the main route. To go the other direction, or cross the highway, they pull into a dedicated lane, typically less than 1,000 feet away, to make a U-turn. There may be a traffic signal at this location.


Reports in 2010 from North Carolina State University​ and in 2017 from the Federal Highway Administration found that:

Reduced-conflict intersections without traffic signals reduced crashes 46 percent compared to conventional intersections(NCSU)
Reduced-conflict intersections with traffic signals reduced crashes 15 percent compared to conventional intersections.  (FHWA)


Project History:

NCDOT completed the Environmental Assessment and Finding of No Significant Impact (EA/FONSI) in December 2018. The EA/FONSI covers all three segments of the U.S.158 (Reidsville Road) corridor, from multi-lanes north of U.S. 421/I-40 Business in Forsyth County to U.S. 220 (I-73) in Stokesdale (Guilford County). NCDOT and the consultant have continued work on Section A of the project. The design for this section has been refined and provides changes that minimize property impacts and improves traffic operation.

Public Involvement

Public Meetings

A public meeting was held on Oct. 10, 2019 in Winston-Salem to obtain stakeholder and public input regarding the project's design.

Although the N.C. Department of Transportation works to minimize the number of homes and businesses displaced by a road project, it is inevitable, in many cases, that a certain amount of private property is needed.
