Locomotive Engineer's Activity Diary

摘要

The goal of this project is to understand both quantitatively and qualitatively how the work scheduling practices of the freight railroads affect the alertness and fitness for duty of train crews. Data were gathered from diaries kept by about 200 engineers employed by six major railroads. These diaries recorded such items as: the quantity and quality of their sleep, estimates of their alertness levels at various times while on duty, time on duty, communting time, and the accuracy ofinformation provided to crews about job-start times. Survey participants were also asked to describe in their own words what they see as the major contributors to fatigue and what they would like to see done about the problerm. There are several applications for the diary data including: (1) quantitative comparisons of amounts of sleep, accuracy of calling information, etc., among various groups of engineers and against other types of workers; (2) guidance to the FRA in its consideration of alternatives to the current Hours of Service Law and accompanying regulations; and (3) development of improved crew-calling software.
