Abstract [en]

The purpose of this master thesis project was to investigate the actual truck driver position. A method to study truck drivers’ sitting positions and their context relations were to be developed and adapted. Recommendations and guidelines for how the truck driving position can be expounded were thereafter to be presented. Three truck segments were identified: long distance, distribution, and construction. The construction and distribution segments were selected for this study. Information about truck drivers’ occupation, working hours, tasks, and truck were gathered in a task analysis. The accomplishment of the study was based on the knowledge from the analysis. Nine truck drivers were video filmed with four miniature cameras while driving, and the first and the fourth working hour were analysed. The drivers’ position was coded in four categories: sagittal back, lateral back, right foot and left foot. The context was coded in two categories: environment and cockpit surroundings. The results showed that the sitting behaviour was quite similar for the construction and distribution drivers. It was quite clear that the driving position was affected by the driving situation, the drivers took different positions depending both on the environment and the cockpit surroundings. Most of the drivers kept a favorite posture in each category for the majority of the seated time. The observed drivers never sat in a fixed posture more than just over a minute and most of them changed position more frequently during the second studied hour. The studied drivers had a good sagittal sitting position and this ought to be kept in the future. The lateral sideway leaning behaviour that affects the road safety is on the contrary recommended to be reduced. It is also important to allow the drivers to change their driving position. The safety belt usage needs to be improved and the low usage frequency of the footrest reveals that the design and placement need to be further investigated.
