Title: FIXED HIGHWAY LIGHTING: DESIGN AND OPERATION
Accession Number: 00272046
Record Type: Component
Availability: Transportation Research Board 500 Fifth Street, NW Abstract: One of the primary functions of the Highway Research Board's Visibility Committee is the accumulation and dissemination of up-to-date knowledge on all aspects of visibility. In carrying out this function it is important to maintain an awareness of current operational policies and practices related to visibility, since these parctices not only reflect current thinking but also influence the direction of future activities. One area within visibility that currently is receiving increasing attention is Fixed Highway Lighting. In particular, there has been growing concern about the lack of international standards and, indeed, the lack of uniformity in practice among the United States, themselves. To document the degree of this non-uniformity in the U.S., and as a first step toward addressing the broader concern over international standards, the Visibility Committee decided in 1972 to survey the States with regard to their current and proposed fixed lighting policies and practices. An Ad Hoc Committee was appointed to prepare and administer a questionnaire. The questionnaire was distributed to state Highway representatives of all 50 states, Puerto Rico and the District of Columbia in late December, 1972. By early Spring, 1973, 49 questionnaires had been returned. This publication is devoted to a non-critical presentation of the information provided by these 49 respondents. The first section summarized the data for ease of understanding, while the second part of the circular presents the raw tabulations upon which the summaries are based. The respondents were asked about: (1) a typical new highway lighting system designed and used by their state; (2) light sources for future use in highway lighting; (3) light sources for future use in highway signing; (4) responsibility for highway lighting design; (5) ownership of completed highway lighting systems; (6) how cost is divided among different levels of government; (7) maintenance responsibility; (8) cleaning and relamping; (9) basis of highway lighting design; (10) glare; (11) energy cost; (12) highmast lighting; (13) new or novel approaches; (14) use of break-away poles.
