In the Philippines, jeepneys are a key mode of transportation, accounting for 40% of public motorized trips. Launched in 2017, the Public Utility Vehicle Modernization Program (PUVMP) proposed modern jeepneys to address air pollution, enhance passenger safety, and alleviate traffic congestion. The Bureau of Philippine Standards issued specifications for four classes of modern jeepneys, focusing on dimensional limits. Despite millions of Filipinos using the Jeepneys, daily exposure to poorly designed jeepneys can lead to Musculoskeletal Disorders (MSDs) among passengers, affecting their ability to work effectively and safely. Existing studies indicate that discrepancies in seat design and measurement exacerbate MSDs. To assess whether modern jeepneys align with the anthropometric measurements of Filipino commuters, researchers collected various dimensions, including seat height, depth, and backrest height. The researchers conducted measurements on 120 Filipino passengers, obtaining eight key anthropometric measurements such as popliteal height and sitting shoulder height. Using z-tests for analysis, it was found that seat width and ceiling height had the lowest percentage of unfit users. A mismatch analysis was created, utilizing the 5th and 95th percentiles of the anthropometric measurements to offer recommendations for improving modern jeepney dimensions. This research highlights the importance of ergonomic design in public transportation to enhance passenger comfort and prevent the onset of MSDs.
