This Safety IDEA project-31 extends the design process for the accessible sleeper compartments to include 3-D digital modeling and anthropometric analyses and uses a full-scale soft mock-up of the sleeper compartment. The use of computer-aided design tools permits human factors constraints, including minimum spatial requirements and reach limitations, to be determined within the conceptual design phase without physical prototyping and data collection. In this ongoing study, physical prototyping in the form of a full-scale soft mock-up is used to validate digital results. Successful validation would indicate that anthropometric digital human models based on regular anthropometric databases may be used to design for populations with reduced mobility, provided that the wheeled mobility devices are modelled appropriately and advance the design process for accessible spaces. The soft mock-up permits spatial evaluation by the general public including people with disabilities. An online survey is also available to gather feedback and the needs and values of the target population. Representatives of the passenger rail industry are involved throughout the project and have been invited to participate in the evaluation of the soft mock up. The results of the project are validated designs for new accessible sleeper compartments for bi-level and single-level rail cars and include seating, sleeping, and restroom spaces. This will be disseminated for use by the passenger rail industry.
