Both perceptual and measurable specifications of accessibility are reviewed and their relevance to transport planning established. The wide variety of analytical forms which can be used to quantify different aspects of accessibility are categorised and grouped by conceptual basis. The different forms of accessibility index are then related to underlying theories which link consumer demand, evaluation and accessibility.
