How do they work?
In a reduced-conflict intersection, drivers on the side road wanting to turn left or cross the four-lane highway will:
- Turn right onto the highway
- Merge into the left lane
- Make a U-turn at a designated median opening.
The way the pavement is configured, you cannot make a left turn onto the four-lane highway or cross both directions of traffic. This reduces potential conflict points and increases safety.
While this might sound like it will take you longer to turn, generally, the delay caused by a traffic signal or just waiting for traffic to clear at a two-way stopped-controlled intersection is greater than the delay caused by the reduced-conflict intersection.
- Improved safety — Studies show a 70 percent reduction in fatalities and a 42 percent reduction in injury crashes where a reduced-conflict intersection is used.
- Faster to build — reduced-conflict intersections can be designed and built in approximately one year. Interchanges typically take 3-5 years and are not practical at all locations.
- Lower cost — reduced-conflict intersections are often less expensive than constructing and maintaining an intersection with a traffic signal and are a fraction of the cost of building an interchange.
