Abstract

An annotated literature survey is presented of 67 articles published in 1957-58. The night accident problem and night driving have received considerable attention. Discomfort glare and glare sensitivity contribute to the night visibility problem. Dynamic visual acuity, measured with a moving test object, seems to have little or no relation to visual acuity measured with a stationary target and considerable research has been directed toward the problems of visibility of moving objects. The problem of the visibility of road markings is discussed by some authors. The advantage of reflectorized license plates is emphasized to reveal the presence of a car. Problems and instruments available for measuring visibility on the roadway at night are discussed. Eye movements and visual gradients from the fovea are discussed.
