ABSTRACT
Tricycles are an established mode of transportation in many parts of Nigeria. However, little attention has been given to ergonomic interaction between it and its users. Therefore, this study focuses on ergonomic evaluation of tricycles and riders in Akure, Nigeria. Anthropometric dimensions (AD) of 200 commuters (90 males and 110 females) were obtained. Measurement of five dimensions of the Tricycle: seat height, seat depth, seat width, backrest height and clearance height were carried out. These dimensions were compared with popliteal height, buttock popliteal length, hip width, sitting shoulder height and sitting stature respectively using match equations. Results showed agreement between the responses of the commuters and the outcome of the analysis obtained from the match equations that the tricycles are not suitable or comfortable for most riders. A large number, (62%) of commuters complained of leg pain due to inappropriate seat height while 42% of commuters complained of back pain. The analysis of the match equations revealed that seat height was inappropriate for about 54% commuters, while backrest height was inappropriate for about 33% commuters. The study revealed that commuters using tricycles are liable to future health issues due to repetitive cumulative trauma disorders and awkward postures. Anthropometric dimensions (AD) of the intended users, if considered, may help to reduce the cumulative trauma disorders as recommended by this study.
