タクシードライバーの休憩の取り方に関する事故反復者と優良運転者の比較

抄録

Appropriate rest is important for reducing accidents involving taxi drivers working long hours. We investigated the relation between the rest of taxi drivers on duty and accidents by analyzing the one-month records of digital tachographs of 21 accident repeaters and 23 safe drivers. They worked for about 20 hours per a shift.　We defined inactivity exceeding five minutes as rest. The dependent variables were the total rest time, the number of rest periods, the maxim continual driving time, and the concordant rate of rest. The concordant rate of rest indicates whether the time and length of rest were regular or not and is the average of the similarity ratio of rest. We compared four variables between accident repeaters and safe drivers. The result revealed that the concordant rate of rest of safe drivers was significantly higher than that of accident repeaters. There was no significant difference in the total rest time, the number of rest periods, or the maxim continual driving time.　We found that the regular rest was important.
