Roadway lighting study : Rte. 264 in downtown Norfolk.
A study of roadway lighting is currently being conducted at several locations in Virginia by using a mobile illumination recording system to obtain lighting measurements. Areas being surveyed include the I-264 interchange area in downtown Norfolk and the Shirley Highway (I-95) between the Springfield and Glebe Road interchanges, which lie south of Washington, D. C. Interim Report No. 1 presents the results of the study of the I-264 interchange area in downtown Norfolk. The illumination in the interchange area is provided by mercury type lamps whereas the adjacent streets in downtown Norfolk are illuminated with high pressure sodium lamps. The results of the survey indicate that the average level of illumination in the interchange area is lower than that which is recommended by the ASA standards. The uniformity of the lighting is also poor and does not meet the accepted standards. By contrast, the sodium lighting in certain areas of downtown Norfolk lying adjacent to the I-264 interchange was found to provide a high quantity and quality of illumination.
