Abstract As the transportation industry continues to evolve, it is urgent that we develop and implement methods for clearly evaluating range of engineering, planning, policy impacts experienced by various population segments. While theories equity have advanced over past decade, such advancements outpace existing fairness large-scale investments disadvantaged communities. In this study, a regional activity-based travel model Bay Area, California used perform an analysis two region’s land-use planning scenarios. Equity outcomes are tested relative three standards: Equality, Proportionality, Rawlsian justice. The primary objective demonstrate usefulness full-scale analysis. We fine-grained distributional measures play important role in examining individual household-level scenarios, can complement Environmental Justice assessments analyses helping explain underlying reasons average group impacts. Distributional further reveal harmful cases when groups most likely experience disbenefits Yet, each type isolation does not tell complete story which scenario deliver more equitable outcomes. Finally, significance applying standards ranking find scenarios will vary according standard, as well how associated evaluation criteria defined.
