Third Generation Simulation Data (TGSIM)

The Intelligent Transportation Systems (ITS) Joint Program Office (JPO) DataHub now provides access to data from the Federal Highway Administration’s (FHWA’s) Third Generation Simulation (TGSIM) project, including detailed vehicle trajectory data and supporting data files, from the project’s data collection efforts. Researchers for the TGSIM project collected the specified data in Chicago, IL (I-90/I-94); Hinsdale, IL (I-294); and in Washington, D.C. (I-395 and on the George Washington University’s Foggy Bottom Campus). This data story offers a concise overview of the TGSIM project data collection, along with details on the data available on ITS DataHub. It also highlights potential uses for the data and provides guidance on how to cite the various TGSIM datasets.
