... 50 LED Roadway Lighting: Impact on Driver Sleep Health and Alertness SDLP because of the presence of roadway lighting. Future research in the area with larger sample sizes could result in a better understanding of this phenomenon.
From page 51...
... Discussion 51   The application of roadway lighting should be considered in terms of several aspects that affect road users and the built environment. These aspects include road safety, energy conservation, road user acceptance, impact on user health, sky glow and light trespass, and impact on the surrounding ecology.
