FHWA'S PHOTOMETRIC AND VISIBILITY LAB

Thanks to investigations and development of new retroreflective materials and the exploratory investigation of various lighting sources, including ultraviolet headlamps and fluorescent materials, at the Federal Highway Administration's (FHWA) Photometric and Visibility Laboratory, "reading" the road and seeing people while driving under inclement conditions and at night are becoming much easier. The lab contains an office, photometric measurement and calibration room, a small workshop and storage room, and an unobstructed laboratory space, painted completely black to minimize light reflections during lab tests and human factors studies under conditions simulating a nighttime environment. The lab has three objectives on research activities: photometric and colorimetric measurements, material studies concerning the use of materials that are used to enhance night visibility, and in-house research.
