Within transport planning, accessibility is generally defined as the ease with which people from specific locations can travel to participate in activities using a mode of transport. The problem with most measures of accessibility is that they lack the capability to evaluate the impacts of transport policies that can directly influence travel decisions. / There is a need for measures of accessibility to be more sensitive to transport policies. This thesis discusses a framework used to develop measures of accessibility that take into consideration the travel behaviour of individuals and other factors that are sensitive to transport and urban planning policies. Such measures provide a valuable tool for transport and urban planners to evaluate both physical improvements to transport networks and the comparison of policies in terms of their relative cost of implementation, usefulness, efficiency and effectiveness. / In addition, this thesis argues that accessibility is more than just overcoming spatial separation between locations. It acknowledges the differences between individuals for whom the measures are calculated, the activities to which individuals need access, the properties of the locations of activities, the transport system that facilitates travel to overcome the separation between individuals and activities, and the effects of available time on accessibility. / Accessibility measures are commonly trip-based as they consider the accessibility from one location to another. Although the trip-based concept is important and useful in transport planning, there is also a need for an activity-based measure of accessibility that focuses on accessibility of people to activities rather than just accessibility between locations. / The accessibility framework is based on travel information collected through travel diaries that indicate the travel patterns of individuals within households. The thesis reports on how such information was used to develop behavioural models to reflect travel decisions by individuals. The behavioural-based measures provide a technique to determine the influence of factors on accessibility and ensure measures of accessibility to be dissected to enable the various components of accessibility to be analysed. These measures of accessibility provide the transport or urban planner the ability to determine what affects accessibility in specific areas and test policies that may rectify the problem. / The accessibility framework was applied to describe the accessibility levels that exist within Metropolitan Adelaide and to evaluate the urban system in terms of accessibility of individuals to activities in areas. The capabilities of the accessibility framework to evaluate both transport and land-use policies aimed at improving accessibility for the people residing in Metropolitan Adelaide to the activities they wish to partake were also demonstrated. / Thesis (PhD)--University of South Australia, 2004.
