LED Roadway Lighting: Impact on Driver Sleep Health and Alertness
Light emitting diode (LED) technology has revolutionized the lighting industry. The dimming and
instant-on capabilities of these light sources along with their high efficiency have allowed lighting
designers to overcome some of the limitations of previous technologies, particularly in roadway
lighting environments. However, concerns related to the health and environmental impacts of
LEDs have been raised.
The TRB National Cooperative Highway Research Program's
NCHRP Research Report 968: LED Roadway Lighting: Impact on Driver Sleep Health and Alertness
seeks to determine the impact of LED
roadway lighting on driver sleep health and alertness.
