Book Description
The project discussed in this report concerned the night use of overhead guide signs, including button and reflectorized copy and all practical combinations of reflectorized and opaque backgrounds. This project was a follow up effort to the literature review by Gordon. Gordon's review found areas requiring further investigation, including the comparison of nonilluminated nonretroreflectorized signs with both illuminated nonretroreflectorized and retroreflectorized signs.
