Driver Oriented Ergonomic Design for Long Distance Heavy Truck Cabins

Abstract Ergonomic design of Long Haulage Commercial truck cabin is a critical determinant of driver safety and occupational health, particularly given the increased severity of accidents involving Long Haulage Commercial trucks in long-haul transportation. Despite this, cabin ergonomics have historically been suboptimal, contributing to elevated road risk and driver musculoskeletal disorders. This study evaluates the ergonomic deficiencies of key Long Haulage Commercial truck cabin components through a comprehensive analysis of driver-reported experiences, demographic characteristics, and operational behaviours. Data were collected via structured interviews and standardized questionnaires administered to professional Long Haulage Commercial truck operators. Statistical analyses, including hypothesis testing, were employed to quantify the significance of ergonomic inadequacies across components such as seating systems, restraint mechanisms, steering assemblies, pedal interfaces (accelerator, brake, clutch), and gear shift controls. Results indicate pervasive ergonomic shortcomings that compromise driver comfort and control efficacy. These findings inform targeted design modifications aimed at mitigating injury risk and enhancing driving performance, thereby contributing to improved Long Haulage Commercial truck cabin ergonomics.
