TRANSIMS IS COMING!

TRANSIMS is a series of integrated transportation and air quality analysis and forecasting models being developed at the Los Alamos National Laboratory. The principal components of TRANSIMS are an activity generator, an intermodal route planner, a traffic microsimulation, and an environmental analysis module. TRANSIMS will offer transportation planning agencies increased policy sensitivity, more detailed vehicle-emission estimates, and improved analysis and visualization capabilities. TRANSIMS is part of the Travel Model Improvement Program (TMIP), a multiyear, multiagency program designed to improve both the analytical tools and the integration of these tools into the planning process. TRANSIMS is the long-term effort to redesign the modeling process from the ground up. The modules developed for TRANSIMS contain many significant advances beyond the four-step models: disaggregate models, simulation, integrated system, highly detailed vehicle emission estimates, and operational tools. The development of TRANSIMS' core capabilities is complete; however, a case study, set in Portland, Oregon, will explore the sensitivity of TRANSIMS software to different types of data.
