整體而言，受訪的客運駕駛有肥胖現象，工時過長，壓力偏高，睡眠習慣不佳，睡眠品質差且有嗜睡現象。駕駛壓力的高低(OR=1.16, p<0.001)、輪班與否(OR=3.63, p<0.05)及BMI (OR=1.13, p<0.05)均會影響睡眠品質；不良的睡眠品質(OR=1.22, p<0.05)會導致嗜睡。至於顧客關係則會顯著受駕駛的不佳睡眠品質(OR=1.19, p<0.05)與較高壓力(OR=1.09, p<0.01)而削弱。
In order to improve the quantity and increase frequency of public transportation, driver shift work had become unavoidable in recent competitive environment. Psychological, or physiological problems and stress usually accompany heavy working load. Drivers were prone to lethargy, or even fall asleep under persistent night working and long term sleep cycle disorder. This situation not only led to lower efficiency and poor service quality, the probability of accidents also increased significantly.
Conveyance of passenger by highway was characterized by heavy load and high speed; therefore, a catastrophic accident should bring a lot of casualties. Driver, who is taking the wheel, should be in his best spiritual and health condition.
In this study, long-distance highway bus drivers were surveyed with structured questionnaire, which was designed according to reviewing relevant literature references. There were 6 domains: personal physical condition, sleep quality, stress scale, somnolence, sleep hygiene and customer relationship. We would also like to investigate the relation among sleep quality, stress and custom relationship. And further, related factors for sleep quality, somnolence and custom relationship were also analyzed.
In general, drivers were overweight and in high stress; had poor sleep quality, improper sleep hygiene and long working hours. Sleep quality of driver was significantly affected by stress (OR=1.16, P<0.001), BMI (OR=1.13, P<0.05), and shift work (OR=3.63, P<0.05). Sleep quality (OR=1.22, P<0.05) is an effective factor for somnolence. As to customer relations, it was significantly whittled by poor sleep quality (OR=1.19, P<0.05) and high stress (OR=1.09, P<0.01).
For the security of public transportation, driver himself and corporation should both pay more attention to abate stress, keep proper figure, reduce, if possible, shift work, and build up correct sleep hygiene for the better sleep quality, and then diminished driver somnolence. Accordingly, customer relationship and public safety would be promoted for the better transportation benefits.
