Efforts made by 47 state highway departments to improve roadway lighting and need for effectiveness ratings; IES's opportunity for progress impels following report on measurements of several roadway lighting systems -- relative visibility and factors; double illumination for equivalent visibility on medium reflectiveness pavement surfaces; computed ratings -- similar and preferable to test ratings; double illumination-brightness for 1/6 sec simulation of dynamics; implementation and use of available seeing factor data; measurements made and data obtained.
