One form of public transport system in the Philippines is the vehicle called tricycle. The design components are a motorcycle and a side car attached with a capacity of 5 passengers including the driver. The current design and construction of the tricycle in the Philippines is mainly focused on aesthetics and not necessarily on the passengers comfort and safety. This research study is about an innovative tricycle design focusing on the comfort and safety of the passengers. The quality of the design was evaluated through data gathered from passengers based on their response to the survey questions on their experience in riding the prototype design. Rapid Upper Limb Assessment was conducted to assess the postural risk of the passengers using survey questions based on the Cornell Musculoskeletal Discomfort Questionnaire. One on one interviews were also conducted to determine the demand of the users’ muscular need and satisfaction. The respondents in this study include the passengers and drivers. Quality Function Deployment was used to determine the initial specifications by evaluating the customer requirements.. Failure Mode and Effect Analysis are efficient method in the assessment of risks involved using the new tricycle design. Ergonomic principles were applied in determining the appropriate dimensions and shape of the passenger cabin and the back side using the concepts of Anthropometry.
