HADRIAN is a digital human modeling (DHM) system that is currently under development as part of an EPSRC funded project in the UK looking at accessible transport. The system is a partner tool to the long established SAMMIE DHM system and aims to address issues with the lack of applicability of DHM tools to inclusive or universal design problems. HADRIAN includes a database of 102 manikins based directly upon data taken from real people, many of whom are older or with disabilities and who span a broad range of anthropometry, age, and joint mobility. This database is combined with a task analysis tool that provides an automated means to investigate the accessibility of a workstation or environment. This paper discusses the issues and subsequent refinement of the tool that resulted from validation using an ATM design case study. In addition the results from a second validation are presented. This second study examines the accessibility of a Docklands Light Railway station in London. The results highlight that whilst physical simulations can be made with a generally good degree of accuracy there are still many opportunities to be explored in the cognitive and emotional areas that can be used to inform designers of accessibility issues during virtual assessments.
