ERGONOMIC ASSESSMENT OF KOROPE MINI BUSES. A RESEARCH PROJECT MATERIAL ON MECHANICAL ENGINEERING
Ergonomics (human factors) as the scientific discipline concerned with the understanding of the interactions among humans and other elements of a system, and the profession that applies theory, principles, data, and methods to design in order to optimize human well-being and overall system performance(The International Ergonomics Association IEA, 2003). Ergonomists contribute to the design and evaluation of tasks, jobs, products, environments, and systems to make them compatible with the needs, abilities, and limitations of people. Ergonomics discipline promotes a holistic, human-centered approach to work systems design that considers physical, cognitive social, organizational, environmental, and other relevant factors Karwowski, 2001; Vicente, 2004; Stanton et al., 2004).
According to Karwowski, 2005, Over the last 50 years, ergonomics, a term that is used here synonymously with human factors has been evolving as a unique and independent discipline that focuses on the nature of human–artifact interactions, viewed from the unified perspective of the science, engineering, design, technology, and management of human-compatible systems, including a variety of natural and artificial products, processes, and living environments. The main aim of ergonomics is to ensure the Human–Technology, Technology–System, Human–System and Human–Machine relationships. Therefore, ergonomists put human needs, ability and limitation at the focus of designing and evaluating tasks, jobs, products, environments and systems.
Korope are examples of mini buses that are used as a fixed routes public transit and passenger carrying buses within Osun state and its locality with the usual colour combination of
blue with yellow stripe. These buses are designed to carry fewer people than the normal full size buses. Although, there are other buses of different sizes and sitting capacity (Between 7 to 30 seats) but korope has the maximum of 7 seating capacity. That is the maximum passenger korope can occupy is 7 passenger; the driver exclusive. These buses are locally built or fabricated in places like Lagos state and in Ibadan.
