本研究的主要目的，在於將生活型態的研究應用於都會區公車座椅的設計；生活型態的研究，可探討出各族群之間的差異性，以設計出滿足不同族群所需求的產品。然而，在面對公車座椅此種「公共設施」之產品設計時，不同族群（消費者）對產品需求的相同特性的探討，將使得生活型態的研究更有意義。本研究以問卷調查進行研究問題資料的蒐集。依據回收資料，經因素分析、集群分析、變異數分析等統計方法，深入探討「生活型態族群」對「公車座椅使用需求」的差異，以及「公車乘客的背景因素」對「生活型態族群」在公車座椅使用需求上的影響。從中分析歸納出都會區公車座椅的設計因素，應用於都會區公車座椅的設計，使理論與實務相結合，期盼能提昇都會區公車的服務品質。

　　　　　The main purpose of this study is to apply the study of life styles to the design of metropolitan bus seats. The study of life styles probes into the difference among group and developes the products to satisfy different groups. When it designs public equipments like bus seats, however, the study of the common demand of life style more meaningful. It also becomes one of the important courses of this thesis. The questionnaire is utilized as the primary tool in gathering data for this research. Probing deeply into the backgrounds of different passengers and their life style by statistically using Factor Analysis, Cluster Analysis, One-Way ANOVA and Two-Way ANOVA to know their differences by using bus seats. According to the results of this study it obtains, it finds the common speciality of the passengers and concludes the factors of designing bus seats depending on sex, age, occupation, gross income, academic degree and ergonomics. It also applies them to the practical design of metropolitan bus seats in order to combine the theory and reality, importantly, promote the quality of bus service.
