Lighting is an important element of roadway safety. Evidence suggests that roadway lighting is usually associated with reductions in nighttime crashes. After several decades of relatively slow and gradual change, light source technologies for roadway lighting are evolving rapidly. Many new options for roadway lighting are available, and there is more information about how light interacts with the human visual system. This informational brochure provides some information about these developments and how they might be incorporated into lighting practices for several types of roadways and locations in New York State. The focus is on replacement of older roadway lighting systems near the end of their useful lives, and on maintaining or improving visibility and safety while minimizing energy use and associated costs.
