Summary:

This TechBrief describes the methodology and results from a closed-course study sponsored by the Federal Highway Administration (FHWA) that addressed brightness, flash patterns, and location of light-emitting diodes (LED). It examined driver detection of cutout pedestrian photographs in the presence of LEDs of various brightness levels and flash patterns, which are placed in different locations within the sign assembly.
