Taxi drivers usually work with prolonged working hours, add itional stress may likely be induced on particular body limbs. Occupational heal th may occur and working efficiency may potentially be affected resulting fr om fatigues, pains or diseases. These problems, however, could be remedied if mo re attention is paid on seating design, the workplace and driving postures adopt ed. Ergonomics design can provide better understanding of those concerned areas. A study was conducted to analyse occupational and health problems related to ta xi drivers. Through ergonomic evaluation of driver’s compartment, the authors m ake recommendations to improve health and safety aspects. Besides, the experienc e of gained from this study using ergonomic design can be extended to other occu pation or products.展开更多
