Abstract
A theory is given for accessibility preferences, based on equilibrium between a desire to have a number of nearly neighbourhood facilities and a desire for separation and insulation from irritation. Reactions to possible changes in the neighbourhood, such as may be caused by a new road were obtained by interview in Chicago suburb. Rank order and paired comparisons measurements were made. Results suggest a model for a neighbourhood evaluation, expremed in qualitative preference scales, A log-normal function for accessibility preference is derived. Substitution effects for the neighbourhood facilities were not examined. The possibility of psychometric analysis for transport investigations is discussed.
