Transportation Secure Data Center

The Transportation Secure Data Center TSDC at https// provides free access to detailed transportation data from travel surveys and studies conducted across the nation. It features millions of data points including second-by-second GPS readings vehicle characteristics and demographics for all modes of travel. NREL screens the initial data for quality control translates each data set into a consistent format and interprets the data for spatial analysis. NREL processing routines add information on fuel economy and road grades and join data points to the road network. NREL maintains the TSDC in partnership with the U.S. Department of Transportation and the U.S. Department of Energy.Before viewing the data for the first time you will be required to fill out a short registration form.If you use TSDC data in a publication please notify NREL at and include a citation in your publication.
