The Effects of Background Lighting on the Usefulness of Navigation Lights.
Abstract
An investigation was made of the deficient conspicuity of navigation lights in harbors. This problem can be solved, and the problem requires two distinct solutions, both of which are necessary. The first solution is the development of what should be considered only short-term measures. The second solution is the regulation of lights that interfere with the conspicuity of navigation lights. This is the only permanent solution to the problem, for purely technical solutions would only involve the Coast Guard in a never-ending struggle to keep one step ahead or, worse, keep up with new types of lights that are being installed along the shoreline.
