Abstract
Traffic accidents were common problems in the implementation of a transportation system, including in West Sumatra Province, Indonesia. Traffic accidents that occur every year were the evidence by the number of traffic accidents that occur every year. One of the causes of traffic violations that result in accidents is the risk of driver fatigue while working. This study analyzed the work-fatigue in the driver of the Intercity in Province bus (AKDP) the scope of this study was all AKDP bus drivers with the origin of Padang City, Bukittinggi City, and Payakumbuh City. Measurement and analysis of work-fatigue were using the reaction timer to light response. The results showed that increasing the number of shifts would increase driver fatigue. 33.33% of drivers run into medium level of fatigue, and 38.89% of drivers run into heavy level of fatigue. The relationship between work-fatigue and the driver's shift correlated very strongly and positively with a correlation value of r = 0.81. The owner of the company needs to take measures to improve management to minimize the level of work on this driver that has the potential to cause traffic accidents.
Highlights
Traffic accidents were common problems in the implementation of transportation systems
Recorded in 2018; there are 24,572 accidents in Indonesia, of which 3.02% occurred in West Sumatra Province (Korlantas Polri, 2017)
According to data from the Indonesian National Police Traffic Corps, the violation factor committed by the driver reached more than 80% of the causes of traffic accidents involving minibusses and buses, especially intercities in the province
Summary
Traffic accidents were common problems in the implementation of transportation systems. According to data from the Indonesian National Police Traffic Corps, the violation factor committed by the driver reached more than 80% of the causes of traffic accidents involving minibusses and buses, especially intercities in the province. One of the reasons for traffic violations is the risk of fatigue at work which can reduce the level of concentration and disrupt the health of the driver for a long time. Long working hours, continued physical and psychological activity, lack of rest time, insufficient rest, excessive stress, chronic health conditions, monotonous work can trigger fatigue (Tarwaka, Bakri SHA and Sudiajeng L, 2004). To analyze the causes of accidents from work exhaustion factors in traffic accidents that occur on bus cars, especially the Intercity in Province (AKDP) buses, fatigue research is necessary to study work-fatigue using a light reaction timer method.
