This report will be of interest to transit managers, bus specification engineers, bus manufacturers, and bus operator workstation component manufacturers concerned with improving the ergonomic design of the bus operator workstation to improve bus operator comfort, and reduce bus operator injuries and related absenteeism and workers' compensation claims. The report provides scientifically validated design guidelines that ergonomically accommodate operators from the 5th percentile female to the 95th percentile male population. The design guidelines address all aspects of the bus operator workstation including the seat, steering assembly, pedals, instrument panels, farebox, and other equipment. While attempting to minimize the amount of required component adjustability to contain cost, adjustment is included in several key components including instrument panels, seat, and steering assembly. It is estimated that the workstation improvements identified in the design guidelines would increase the price of a standard transit bus by approximately $6,000, with a payback period of between 3.5 and 8 years based on direct cost savings associated with estimated reductions in bus operator injuries. Indirect cost savings such as the need for fewer replacement operators would further reduce this payback period.
