CRITERIA FOR HIGHWAY TUNNEL LIGHTING DESIGN

MODERN HIGHWAYS DESIGNED TO ACCOMMODATE HIGH-SPEED, HIGH/ VOLUME VEHICULAR TRAFFIC INCORPORATE IN THEIR CONSTRUCTION NUMEROUS TUNNELS AND UNDERPASSES. MANY OF THESE STRUCTURES REQUIRE FIXED LIGHTING TO PROVIDE ADEQUATE VISIBILITY FOR THE ROAD USER. INFORMATION OBTAINED DURING A NATIONAL SURVEY OF THE LIGHTING SYSTEM IN MOST OF THE MAJOR TUNNELS THROUGH- OUT THE UNITED STATES IS PRESENTED AND THE IMPORTANT LIGHTING FEATURES NOTED DURING THE SURVEY PREDISCUSSED. FACTORS FOR DETERMINING WHICH TUNNELS AND UNDERPASSES SHOULD BE LIGHTED ARE SUGGESTED. FACTORS WHICH MUST BE CONSIDERED BY THE DESIGNER WHEN SELECTING LIGHTING CRITERIA FOR A SPECIFIC PROJECT ARE OUTLINED, AND GUIDE-LINES FOR BOTH DAY NIGHT LEVELS OF ILLUMINATION IN THESE FACILITIES ARE SUMMARIZED. /AUTHOR/
