Cab Ergonomics

UMTRI researchers have conducted detailed studies of truck driver posture. The effects of cab geometry and driver attributes have been quantified through statistical analysis of data measured in laboratory mockups and in trucks driven on-road. The resulting posture-prediction models are used by truck manufacturers to design more accommodating and safer truck cabs. UMTRI has also developed improvements to the SAE eyellipse, seating accommodation, and reach models, which were based on out-of-date driver body dimensions and cab configurations that are not representative of modern trucks. These tools allow optimization of cab layout to maximize comfort and safety while meeting ergonomic objectives and minimizing cost.
