From page 36...
... Additional considerations for LED luminaires include • Use of 4000K CCT sources to assist in the detection distance for pedestrians and hazards at these facilities, • Levels for adaptive lighting at the facilities that vary with the approach roads, and • Vertical lighting levels in crosswalks at roundabouts that meet the same requirements as crosswalks at intersections. Key Issues for Roundabouts, Interchanges, and Intersections • Consider 4000K CCT sources for roundabouts, interchanges, and intersections.
