An analysis of bus interior headroom for future design applications

This research investigated the contextual underpinning and longevity of Australian vehicle standards for route bus passenger headroom—standards developed around Internal Combustion Engine (ICE). With growing interest in Electric Vehicle (EV) technologies, Australian Design Rule (ADR) 58.6 Head Room was examined for passenger safety, comfort and relevance to potential future vehicle design. Four bus interior configurations were modelled to visualise the applications of ADR 58.6. These configurations were then analysed by comparing them to anthropometric data to determine whether accommodation was appropriate. The results found that ADR 58.6 only assures sufficient passenger accommodation when applied in a rear engine, low-entry route bus. A second, qualitative, analysis compared the ceiling height of buses to other public transport vehicle interiors. Results of this comparison contribute an understanding of what may be culturally acceptable as a new standard. Research discovered that current Australian route bus headroom standards only give a satisfactory result when applied to a specific ICE configuration. When designing for alternative ICE configurations or EV drive technologies, these standards may lead to potential problems for passenger safety and comfort. Findings highlight the need to revise ADR 58.6 ensuring relevance to advancements in technology and vehicle design. Recommendations are made to this effect.
