DAY AND NIGHT VISIBILITY OF PUBLIC EMPLOYEES ON THE STREETS AND HIGHWAYS

Visibility can be shown to be the major nighttime problem in pedestrian accidents by comparing day-night accident statistics; it is 18 times as dangerous for pedestrians at night than in day time, considering exposure rates. The trend is for construction activities that cause the greatest interference with traffic to be carried out at night. The conspicuity of the workman both during the day and at night is important for safety. The study reported shows that present headlight systems, particularly with the high degree of low beam usage, do not provide enough illumination to render pedestrian workmen visible under many roadway conditions. This study examines the supra-threshold aspect of conspicuity which is needed to alert a complacent, sidetracked, or inattentive driver to the presence of a person or object in the roadway.
