Abstract:This report studies the complex nature of equity within transportation systems, revealing its wide aspects and implications beyond simple access to mobility. Through an extensive literature review, the report underscores the interconnectedness of transportation equity with socioeconomic disparities, environmental sustainability, public health, traffic safety, and social cohesion. It discusses the challenges and barriers to achieving equitable transportation, as well as strategies for improvement and future directions for research. Practical insights were gained from interviews with professionals experienced in maintaining transportation equity, enriching the theoretical foundations with real-world applications. These discussions informed the development of a transportation equity assessment model and led to actionable recommendations and policy implications. The report introduces innovative methodologies for evaluating infrastructure equity, including an equity-based limit state function and agent-based equity modeling (ABEM), offering a new framework for assessing inequality and identifying areas for intervention. Emphasizing the importance of integrating equity considerations into transportation planning, this study argues for equity as a fundamental pillar in developing sustainable, efficient, and just transportation networks. It calls for future research to refine equity metrics, validate them with extensive datasets, and explore their implications for enhancing infrastructural equity. Collaborative efforts among experts, communities, and governments are highlighted as crucial for addressing disparities and advancing toward equitable transportation solutions.
