The Use of Headlamps in Lighted Streets

摘要

Three surveys on the usage of headlamps in lighted streets were carried out in the winter months of 1976, 1977 and 1978 respectively. The 1976 and 1978 surveys were conducted by the Statistics Directorate of the Department of Transport, and were designed to assess the overall rate of usage of headlamps in Great Britain. The 1977 survey was conducted by the Transport and Road Research Laboratory, in order to measure changes since 1968/69 in the rate of headlamp usage in six large cities. The 1977 survey showed that headlamps usage in six cities is now much more prevalent than in 1968/69 in good as well as in poor lighting conditions.
