STUDY OF THE NATIONAL STANDARDS FOR DIRECTIONAL AND OTHER OFFICIAL SIGNS. OVERVIEW OF THEIR ADEQUACY
The report contains the results of an evaluation of the National Standards for Directional and Other Official Signs (Part 21, Section 131(c), Title 23, United States Code). It is the third in a series of three reports. The other reports in the series are: FHWA-RD-116--Study of the National Standards for Directional and other Official Signs. Synthesis Report. Truman M. Mast, Office of Research, Federal Highway Administration. FHWA-RD-117--Study of the National Standards for Directional and other Official Signs. Laboratory Evaluation. A. G. Klipple and K. M. Roberts, Office of Research, Federal Highway Administration. The results of an evaluation of the Standards conducted by the National Bureau of Standards are presented in this report. The evaluation method made use of a literature review, two different theoretical models and expert opinion. It was concluded that for many speeds, sign locations, and driver characteristics, signs conforming to the Standards but designed for extreme cases of message length and content are inadequate.
