During the development of this report, terminology in the study of accessibility was identified as inconsistent. The authors have developed the following figure (figure 1) to clarify terms such as accessibility planning, accessibility policy, accessibility analysis, accessibility audits and accessibility interventions. This report is specifically concerned with ‘Modelling and analysis’.
