ABSTRACT
Table 1.1 shows the various formal definitions of accessibility - mainly used in the regional science literature - and implicitly underlines how accessibility has been related in the past to the concepts of nearness, proximity, ease of spatial interaction, potential of opportunities for interaction, or potentiality of contacts with activities or supplies (Weibull 1980, p. 54). In other words, accessibility was considered a property of configurations of opportunities for spatial interaction (Weibull 1980, p. 53).
