Abstract
Photogram metric data collected in the SAE U.S. Truck Driver Anthropometric and Workspace Study were used to develop functional workspace models to describe where truck driver eyes, heads, stomachs, knees and seats were located in vehicle space. These models describe the probabilistic location in heavy truck space of the body landmarks of populations of truck drivers with various percentages of males and females as a function of vehicle packaging parameters. These models can be used to determine visual accommodation, head clearances, clearance between the stomach and steering wheel, knee clearance to the instrument panel surface and the location and amount of seat travel necessary to accommodate certain percentages of users with a certain cab design. Models were developed for truck driver populations with 50%/50%, 75%/25%, 90%/10% and 95%/5% male to female ratios. This distribution of models allows the designer to determine accommodation for several potential user groups.
