Sustaining the relevance of transportation planning and forecasting in a fast-changing world

Abstract

Transportation planning and forecasting have long been essential in guiding investment and policy decisions and shaping transportation systems. However, rapid technological advancements, shifting societal values, and the lingering effects of the COVID-19 pandemic have challenged the relevance and accuracy of traditional forecasting models. This paper examines the evolving context of travel behavior, highlighting the limitations of existing models in capturing new trends such as telework, e-commerce, and induced demand. It advocates for the development of more dynamic, data-driven, and context-sensitive modeling approaches that can better accommodate these changes. The paper also discusses the need for planners and forecasters to engage with stakeholders to ensure that models remain effective tools for decision-making in an increasingly complex and uncertain world.
