What is one major challenge faced by traditional modeling frameworks in transportation planning?

Transportation planning involves understanding and managing complex systems that include numerous variables, interactions, and feedback loops. Traditional modeling frameworks often simplify these complexities to make analysis more manageable or to fit within computational limitations. This oversimplification can lead to significant inaccuracies, as it may ignore critical factors influencing transportation patterns, such as social behaviors, environmental impacts, and land use changes. As a consequence, relying solely on these simplified models can result in ineffective planning decisions that do not adequately address the realities of transportation needs in urban and rural contexts alike. This challenge highlights the importance of more sophisticated or integrated modeling approaches that can capture the nuances of transportation systems better.
