Increasing safety, decreasing T-bone crashes

Reduced Conflict Intersections

What are they?

Reduced Conflict Intersections are intersections that decrease fatalities and injuries caused by broadside crashes on four-lane divided highways. In some parts of the country, RCIs are sometimes referred to as J-turns or RCUTs.

Why do they work?

A typical four-lane divided highway intersection has 42 possible vehicle conflict points. RCI's reduce conflict points to as few as 18.

With an RCI, drivers from the side street only have to be concerned with one direction of traffic on the highway at a time. You don’t need to wait for a gap in both directions to cross a major road. Traditional four-lane divided highway intersections have an elevated risk of severe right-angle crashes (commonly called “T-bone” crashes), especially for drivers attempting to cross all four lanes of traffic or turn left. At a traditional intersection, motorists from the side street need to look in both directions to cross a four-lane divided highway. Left turns require the same level of attention.

How do they work?

In an RCI, drivers always make a right turn, followed by a U-turn. Motorists approaching divided highways from a side street are not allowed to make left turns or cross traffic; instead, they are required to turn right onto the highway and then make a U-turn at a designated median opening. This reduces potential conflict points and increases safety. Generally, the delay caused by a signal is greater than the delay caused by the RCI.
