Researchers in the UMD Transportation and Land use specialization study the interaction between transportation and land use, examining how it affects socio-economic activities and movement of people and goods. Researchers contribute to understanding of the impacts of density, diversity, and design of the built environment on transport accessibility, travel behavior, and mode choice on one hand and the impacts of effective transportation system on economic development, land use change, neighborhood livability, and environmental sustainability on the other. One main focus is on transportation demand modeling that predicts travel demand of passenger cars, trucks, and public transit and the distribution of generated trips within a transportation network to examine potential outcomes of various policies and planning measures. A grant from the State of Maryland supports a number of faculty and students to develop and operate the Maryland Statewide Transportation Model (MSTM). In addition, researchers conduct studies on public transit planning and management, transportation economics and finance, travel behavior analysis and modeling, sustainable transportation, and equity issues in transportation. Students and faculty in this specialization come from the fields of planning, engineering, economics, geography, regional science, public policy, sociology, and architecture and design.
