Inclusive Transit Design: Ergonomics, Experience and Equity in Public Transport Interiors

Inclusive Transit Interiors: Foundations, Frameworks, and Design Imperatives

Priya Tyagi — 2026-07-16

Public transport interiors are critical yet underexplored settings in urban design and mobility research. This chapter examines transit interiors as social and spatial infrastructures that shape comfort, safety, wellbeing, accessibility and perceptions of inclusion. Drawing on a qualitative, theory-driven synthesis of literature from transport studies, interior architecture, ergonomics, environmental psychology, human-centred design, and disability and inclusion studies, the chapter develops a conceptual framework for inclusive transit interior design. The framework brings together Universal Design, inclusive ergonomics, human-centred and empathy-based design, and sensory and cognitive accessibility. The discussion shows that physical accessibility, although essential, is not sufficient to secure equitable participation in public transport environments. Inclusive transit interiors must also respond to sensory diversity, cognitive load, emotional comfort and social interaction, particularly under conditions of crowding, time pressure and stress. The chapter considers how interior elements, including seating, circulation, lighting, materials, wayfinding systems and information interfaces, influence passenger experience and operational outcomes. Its scope includes rail, metro, tram and bus environments, as well as users with disabilities, older adults, neurodivergent passengers and people experiencing temporary impairments or situational vulnerability. Rather than offering mode-specific design guidelines, the chapter clarifies concepts and identifies relationships between physical design, sensory conditions, cognition, emotion and social interaction. By integrating fragmented knowledge across design and transport disciplines, it provides a theoretical foundation for later research and design practice concerned with safer, more comfortable and more equitable public transport systems. The proposed framework can support policymakers, transport authorities, designers and researchers in developing mobility environments that accommodate diverse user needs while recognising transit interiors as lived, embodied and socially meaningful spaces.

Designing for Young Urban Commuters: Accessing Inclusive Ergonomics in Metro Transit Interior Design

Gilbert Shanpen Yanthan — 2026-07-16

Transit interiors play a vital role in supporting comfort and convenience for urban travellers; however, they are often designed without sufficient consideration of end users. In many cases, public transport interiors remain limited to basic accessibility compliance, leading to problems such as inadequate space allocation, inefficiently positioned grab handles, insufficient tactile guidance, congestion and other usability barriers. This research proposes the integration of inclusive ergonomics into the interior design of urban transport systems. A mixed-methods approach was used, comprising a review of global literature and an exploratory survey of 31 metro users from varied demographic groups, who assessed accessibility, seating, wayfinding and safety. The findings indicate that positive attributes included good signage (71%), adequate lighting (68%) and clear emergency systems (74%). Conversely, weaker areas included seating comfort (50%), the placement of grab handles (42%) and circulation space (39%). Although contemporary metro interiors provide certain basic accessibility functions, they do not consistently achieve full inclusivity, particularly for users who require additional physical or sensory support to travel comfortably and confidently. Transit interiors should therefore be understood not only as functional spaces but also as environments that address physical and emotional needs. When implemented effectively, inclusive ergonomics can support dignity, safety and security within public transport systems. As this is a pilot study with a relatively small sample, the findings provide preliminary observations on inclusivity challenges experienced by young metro users.

Human-Centred Interior Design in Underground Transit Spaces

Ashish Chauhan — 2026-07-16

Underground transit spaces, including metro and subway stations, are essential components of urban mobility, yet their enclosed, artificial and often crowded conditions can reduce perceived comfort and safety. This study examines how interior design elements influence user perceptions of comfort, safety, accessibility, wayfinding and environmental quality in underground transit environments. The research adopts an exploratory, user-oriented approach combining survey responses, observational fieldwork and visual design analysis across selected metro systems, including Seoul Subway, London Underground and Delhi Metro. Survey items addressed comfort, safety, accessibility, wayfinding and aesthetic quality using Likert-scale and open-ended questions. The findings indicate that seating, cleanliness, temperature and air quality are central to comfort, while CCTV, adequate lighting, clear signage and staff presence contribute to perceived safety. Wayfinding remains uneven, with many users relying on visible signs and maps, supported by digital tools where available. Accessibility features, particularly ramps and lifts, were considered important for inclusive use. Aesthetic responses were mostly neutral, although public art, greenery and distinctive architectural features were preferred as ways to reduce monotony and improve the experience of underground travel. The study argues that underground transit interiors should not be treated solely as circulation infrastructure but as human-centred public environments. Design strategies such as clearer navigation, more comfortable seating, improved lighting, durable and cleanable materials, biophilic references and universal access can support safer, more legible and more emotionally supportive transit spaces. The findings are indicative and provide a basis for design recommendations rather than statistically generalisable conclusions. It also supports publication-ready discussion of interior interventions without extending claims beyond the reported findings.

Material Innovation in High-Traffic Metro and Transit Interiors: Balancing Durability Safety and Aesthetics

Roopali — 2026-07-16

The increasing trend towards urbanisation and dependence on public transport has greatly increased the demand for high-quality metro interior elements that are safe, durable, hygienic, and aesthetically acceptable. Materials used in such spaces should combine durability with passenger comfort. These interiors are frequently exposed to high levels of wear, vandalism-related damage, hygiene challenges, and fire-resistance requirements. Balancing longevity, visual quality, and passenger comfort when selecting suitable materials is therefore a complex task. This research paper explores the use of innovative materials for walls, flooring, and seating in metro interiors. It attempts to address the balance between longevity, aesthetics, and passenger safety. To achieve this aim, the study used a literature review, observations, and a survey with responses from twelve participants. The fire resistance, flexibility, and resistance to vandalism of the assessed materials were considered. Their comfort and hygienic properties were also analysed. The findings indicate a preference for simple non-slip rubber and textured plastic flooring. Participants also preferred modular padded seating and wall finishes with a natural feel. Greater passenger confidence was associated with visible fire-safety markings on surfaces, whereas visible damage and wear negatively affected perceptions of safety and cleanliness. Material innovation was associated with higher user satisfaction but presented additional challenges within the transit environment. Intelligent, modular, and sustainable materials can enhance aesthetic qualities while remaining functional. This work is relevant to designers and transit agencies because it identifies resilient, hygienic, and aesthetically suitable materials for transit environments. Future research should focus on cost-efficient, intelligent, and modular material systems. Although investment in subway systems has increased, limited research has examined the impact of innovative materials on safety, maintenance, durability, and passenger experience. This work addresses this gap through surveys, observations, and a review of existing literature on flooring, seating, and wall materials.

Spatial and Sensory Design in Metro Transit Interiors: Impacts on Commuter Emotional Well-Being

Deepak Kumar — 2026-07-16

Metro transit interiors are everyday public environments that may influence how commuters perceive comfort, safety, and emotional ease during travel. This study examines how selected spatial and sensory design features of metro transit interiors are associated with commuter emotional well-being. The focus is placed on lighting, acoustics, materiality, ceiling height, visual quality, and selected biophilic design elements. An exploratory mixed-methods approach was used, based on survey responses from 12 regular metro users. The questionnaire included Likert-scale items and open-ended questions to capture commuter perceptions of stress, comfort, and design preferences within transit settings. The findings suggest that poor lighting, excessive noise, limited spatial openness, and visually monotonous interiors may contribute to discomfort during commuting. In contrast, respondents associated high ceilings, adaptive lighting, natural materials, greenery, art, and calmer sound environments with improved emotional comfort. Natural light, plants, visual interest, and softer material qualities were frequently perceived as supportive features within transit interiors. The results also indicate that announcements and sound environments require careful balancing, as they are necessary for information delivery but may contribute to irritation when experienced as intrusive. Because the study is based on a small exploratory sample, the findings should be interpreted as indicative rather than generalisable. The results nevertheless highlight the importance of integrating human-centred, sensory, and spatial design considerations into metro transit interiors. Design strategies that improve lighting quality, acoustic comfort, material warmth, spatial openness, and visual engagement may contribute to more comfortable and emotionally supportive commuting environments.
