MEASUREMENT OF DIRECTIONAL REFLECTANCE OF PAVEMENT SURFACES AND DEVELOPMENT OF COMPUTER TECHNIQUES FOR CALCULATING LUMINANCE

A directional reflectance goniometer was developed and used to measure the directional reflectances of eleven nine-inch pavement core samples, five asphaltic concrete and six portland cement concrete. Because of the large amount of data involved, an electronic data processing program, known as HILITES, was developed to handle the collected data. The program is written for an IBM 360/75. It is a highly flexible program providing a relatively simple means of combining lamp/luminaire candlepower arrays with pavement directional reflectance data to calculate illumination, pavement luminance, and glare. Results of calculations are presented in the form of a printout of the highway grid and/or summary tables. /HRIS/
