This MRP presents the results of a qualitative study designed to explore the extent to which commuters’ attitudes and behaviors inadvertently foster exclusionary practices towards other riders in Tehran Subway system. Thirteen frequent users of the subway were selected as participants and asked to keep a diary documenting their observed and practiced behaviors within subway cars over the course of two weeks. The data collected was analyzed using thematic analysis. The findings indicate that subway users unconsciously and implicitly assert a sense of ownership over seats and spaces within the subway cars, leading to the privatization of public spaces. The study discusses the implications of this phenomenon on the inclusiveness of subway interiors and suggests the importance of promoting indirected citizenship behaviors rather than directed citizenship behaviors. Consequently, the MRP suggests a range of design interventions, including product, environment, service, and policy recommendations, to increase awareness and engagement in indirected citizenship behaviors on public transportation.
