Equity and Spatial Justice Perspectives in Transportation

The concepts of equity and spatial justice may be relatively vague and therefore susceptible to different interpretations and metrics, leading to different evaluation perspectives. Thus, our central objective in this work is to explore the scientific production around these two concepts through the lens of transportation, focusing on their connections and interpretations. A mixed-approach analysis (network analysis and semi-systematic review) using Scopus, Web of Science, and Transportation Research International Documentation databases and VOSviewer software reveals that for transportation-related research, equity is more prominent than spatial justice. Accessibility emerges as a key concept for evaluating distributive issues in both contexts. The limited number of papers found may suggest either a gap in research or a mismatch between the terms within the field.
