— Driving in Jakarta as capital of Indonesia can be very exhausting due to high traffic density. The burden of public vehicle drivers such bus driver is heavier, since they are dealing with the traffic during their work. An increasing vehicle owned, flow intensity from urban area has large effect to traffic density in certain time. Bus Rapid Transport (BRT) becomes one of highly demanded transportation system for Jakartans and worker from urban area. In this background, research on fatigue from driving addressing BRT’s driver becomes a critical issue in ensuring safe operation. In this study a workload evaluation, sleepiness and motivation level, self-rated fatigue and the salivary amylase test was established to evaluate fatigue level from 3 services route and 2 different shifts with total 45 participants. The study, designed to collect data directly to the BRT’s driver who was on duty, before and after their services. Based on anova analysis, it reveals that different shift could affect fatigue levels (p<0,05). Different shift also affect stress level due to different workload (p<0,05). Suprisingly, the condition doesn’t affect driver’s motivation level. As a conclusion, early shift had a larger influence on stress and sleepiness level as one of fatigue indicator, a rotation schedule may help to overcome the problem.
