"HILITES"- A COMPUTER PROGRAM FOR HIGHWAY LIGHTING DESIGN

TO AID THE NIGHT-TIME DRIVER, A NEW METHOD FOR HIGHWAY LIGHTING DESIGN IN THE FORM OF A COMPUTER SYSTEM WAS RECENTLY DEVELOPED AT WEST VIRGINIA UNIVERSITY. THE HIGHWAY ILLUMINATION AND LUMINANCE, INVESTIGATION, TESTING, AND EVALUATION SYSTEM (HILITES) PROVIDES A PROCEDURE FOR LIGHTING DESIGN BASED ON LUMINANCE RATHER THAN ILLUMINATION AS THE BASIC DESIGN CRITERIA. GLARE AND THE ASSOCIATED LOSS OF VISIBILITY TO THE MOTORIST ARE ONE ASPECT CONSIDERED BY THE SYSTEM. PRESENT HIGHWAY LIGHTING DESIGN METHODS USE ILLUMINATION AS THE BASIC DESIGN VARIABLE AND TEND TO DISREGARD THE EFFECTS OF GLARE, IGNORING THE FACT THAT REFLECTED LIGHT FROM THE PAVEMENT SURFACE IS THE ONLY LIGHT AVAILABLE TO THE DRIVER FOR EVALUATING THE HIGHWAY SURFACE. THIS AMOUNT OF REFLECTED LIGHT DETERMINES THE LUMINANCE OF THE PAVEMENT SURFACE. THE FLEXIBILITY AND COMPREHENSION OF HILITES IS SHOWN BY THE LIST OF FUNCTIONS IT PERFORMS.
