The transmission of navigational language is increasingly communicated by icons and visual indices. The research in this paper will examine the question of how to design inclusive navigational signage using pictograms to address the differing literacy levels in the local language and script for urban public transportation. Through theory of semiotic analysis and examining international and historical case studies, principles of inclusive design will inform a signage system, which will be used to create a new proposed guideline. This guideline will inform digitally-implemented navigation communication in urban settings, such as Toronto’s Transit Commission (TTC) subway system and underground walkway, the PATH. Findings are used as case studies to illustrate the application of the system. The physical environment in which the pictogram systems are created for must be specific to that environment only and cannot be interchangeable, which may include cultural implications. Recognizing that this nuance exists, inclusive navigational signage will need to include supplemental modes of communication, such as QR codes, to address those knowledge gaps for individuals with low situational literacy who may not know the local language or culture.
