Abstract

Public transportation in the form of buses or minibusses is one of the modes of transportation that helps people travel from one city to another in Indonesia. Travel bus is a form of public transportation in West Sumatra and contributes to a high number of traffic accidents in the province. The high number of traffic accidents related to travel buses is mainly caused by factors and the behavior of drivers. Meanwhile, from various perspectives it is found that risky driving behaviors are often associated with work stress by drivers and work stress can also be caused by various factors, one of which is fatigue. This study aimed to determine the effect of psychosocial work stress on risky driving behaviors in travel bus drivers, to examine whether fatigue is a cause of the relationship between psychosocial work stress and risky driving behaviors in travel bus drivers, as well as provide suggestions in the form of interventions that can be done to reduce risky driving behaviors for travel bus drivers in West Sumatra. This research was conducted using a survey method for travel bus drivers using three questionnaires adapted from the Demand-Control-Support Questionnaire (DCSQ), Checklist Individual Strength (CIS), and Driver Behavior Questionnaire (DBQ). The relationship between psychosocial work stress and risky driving behavior, as well as the mediation of fatigue (general and work-related) in this relationship was tested using path analysis (Structural Equation Models/SEM) with the help of SmartPLS 3.0 software. In addition, preventive and improvement measures can be identified so that travel bus drivers can drive in optimal conditions and avoid the risk of accidents that could happen in the future. Based on the results of the research that has been done, it is found that the risky driving behavior of travel bus drivers is significantly influenced by factors of psychosocial work stress and fatigue. Next, fatigue does mediate the relationship between psychosocial work stress and risky driving behavior. In other words, the increase or decrease in the level of driver fatigue does significantly affect the effect of psychosocial work stress on risky driving behavior. The type of mediation relationship that occurs based on the results of this study is partial mediation in the form of complementary mediation. Furthermore, anticipation or prevention is carried out by analysing indicators or risky driving behavior carried out by travel bus drivers. Cause and effect analysis is carried out to find out what factors can lead to risky driving behavior. And finally, administrative control is carried out in this study by creating work procedure or SOP that can reduce the potential for drivers to engage in risky driving behavior.
