The Influence of Individual Characteristics and Job Factors on Traffic Accidents Through Work Stress on Drivers Two Wheels (Online Motorcycle Taxi) In Makassar City

Introduction: Traffic accidents in Indonesia have risen sharply, with 94,617 cases in 2023 (up 34.6%), dominated by human factors (61%), and the rise of online motorcycle taxis —with 4 million drivers—contributing to the problem due to low safety awareness and high work-related stress, with 41% of workers worldwide affected by stress and Indonesia ranking 9th in Southeast Asia. Methods: This study used a quantitative approach with a cross-sectional design. A total of 106 respondents were selected using accidental sampling techniques. Data were collected through questionnaires involving various variables such as age, length of service, working hours, mental workload, and traffic accidents, as well as using a cocorometer to measure objective work stress. Results: Results at a 95% confidence level or CL = 0.05 indicate that age and length of service have a significant effect on work stress (p=0.001; p=0.000), and age and length of service also have a direct effect on traffic accidents and a significant mediating effect through work stress (p=0.032; p=0.022). Working period does not influence work-related stress or traffic accidents (p > 0.05), and the mediating effect of work-related stress is also not significant (p = 0.142). Working hours and mental workload significantly influence work-related stress (p=0.007; p=0.009), but only mental workload directly influences traffic accidents (p=0.007), with both having work-related stress as a significant mediator (p=0.048; p=0.036). Conclusions: Age, working period, working hours and mental workload significantly affect traffic accidents both directly and through work stress as an intervening variables.
