The Transportation Laboratory (TransLab) is the research group in transportation engineering and planning in the Department of Civil, Materials, and Environmental Engineering. Current research activities pertain to travel behavior analyses, urban travel forecasting methods, emissions modeling, and the properties of solutions to the traffic assignment problem with fixed and variable demand. Faculty with expertise in agent-based modeling, travel behavior analysis, air quality modeling, transportation planning, and transportation economics work with undergraduate, masters, and doctoral students interested in transportation. Research is built around transportation planning and operations and is oriented towards methods for the planning, design, and operation of surface transportation systems. Solutions to problems in surface transportation facilities (infrastructure) are sought through the application of optimization and simulation methods. Our well-established program has strong faculty support and well-developed interactions with the Urban Transportation Center (UTC), an interdisciplinary research center at UIC. The lab has working relationships with local, regional, statewide and national agencies such as the Chicago Metropolitan Agency for Planning (CMAP), Chicago Department of Transportation (CDOT), Illinois Department of Transportation (IDOT), Illinois Center for Transportation (ICT), US DOT, Argonne National Lab (ANL), and the National Science Foundation (NSF).
