Transportation and Land Development

The Transportation and Land Development Committee (ADD30), a standing committee of the Transportation Research Board (TRB), was established in 1972 to improve the understanding of the interrelationships between transportation and patterns of urbanization, along with the economic, social, and environmental consequences of transportation and land development choices. Topics that fall within the committee’s purview include: the effect that transportation infrastructure has on urban form and development; the impact that urban form, development, and design has on travel behavior; the impact that all the above factors has on energy efficiency, sustainability, and resilience of our cities and regions; and  tools and techniques for understanding and influencing these relationships. This article has been prepared for the TRB’s 2020 Centennial to take stock of the transportation-land development field, review the committee’s accomplishments, and outline future directions for research on transportation and land development.
