Dynamic equity in urban amenities distribution: An accessibility-driven assessment

Abstract

The continual challenges exist in attaining an equitable allocation of urban amenities. In order to render this objective attainable as well as practical in real-world scenarios, it is imperative to transition from a static conceptualization of equity to a dynamic notion of equity. To assess dynamic equity in the context of Dhaka, we collected data for two distinct time periods, 2005 and 2018, and calculated integrated accessibility indices using enhanced two-step floating catchment area method. We then responded to these questions: a) Has there been an increase in the level of accessibility? b) Is the changed accessibility being shared more equally or unequally? c) Do members of underprivileged groups enjoy greater access than members of privileged groups? d) Is the underprivileged population enjoying progressively increasing access over time? The results indicate the distribution of accessibility exhibits a pattern, wherein individuals belonging to the underprivileged group experience lower accessibility benefits, while individuals in the privileged group enjoy better accessibility. The sole reason for optimism regarding the distribution pattern lies in the narrowing of the accessibility gap between the privileged and underprivileged. Moreover, the accessibility distribution becomes more equal within the underprivileged group, while becoming more unequal within the privileged group.
