Transportation modeling is a research field and methodological approach focused on quantitatively analyzing and predicting the movement of people and goods within transportation systems. This discipline investigates the complex interactions between travel demand, network supply, and behavioral responses, employing mathematical models, statistical techniques, and simulation methods to represent and evaluate system performance under various conditions. Its significance lies in providing critical analytical support for urban planning, infrastructure investment decisions, policy formulation, and operational management aimed at improving efficiency, accessibility, sustainability, and resilience of transportation networks.
