Abstract: This paper discusses a framework used to develop measures of accessibility that take into consideration the travel behaviour of individuals in addition to other factors that are sensitive to transport and urban planning policies. The accessibility framework determines the benefit or need for an individual or group of people to travel to an activity. The framework revolves around a hierarchy of decisions individuals make when deciding to participate in an activity. The behavioural models within the accessibility framework are built from travel information collected through travel diaries that indicate the travel patterns of individuals within households. The framework is activity-based rather than trip-based. The capabilities of the accessibility framework to evaluate transport and land use policies are demonstrated to evaluate the impacts of (1) a major road project and (2) a land use policy (aimed art increasing regional employment opportunities) in metropolitan Adelaide. The results from the accessibility framework show how the impacts of the initiatives are distributed across the metropolitan area
