Abstract

|
|
The author has investigated the occupational effects of driving upon the general health of drivers with emphasis to the degree of fatigue.
The study consisted of 27 bus drivers and 19 taxi drivers.
The investigation was performed by objective tests such as flicker test, hearing loss test and white blood cells count and recognition of fatigue was obtained by personal interviews.
The results are as follows:
1. Flicker values were reduced gradually as the driving time increased. Significant differences in flicker value were found before and after 8 hours work and after 18 hours work, respectively.
2. Difference of hearing acuity before and after driving was not significant.
3. The numbers of leukocyte were increased significantly after driving.
4. After driving neurosensory fatigue occurred most commonly and was followed
by physical and mental fatigue.
5. The rate of mental and physical fatigue was the highest among under 39 age group. In case of neurosensory symptoms, the highest rate was noted in fifth decade group.
6. The shorter the driving career, the greater rate of mental and physical fatigue was found. Neurosensory fatigue was more common in those with longer career.
