Users are advised to read the rest of the metadata record carefully for additional details. The Travel Monitoring Analysis System (TMAS) Station Dataset is created through a collaboration of state agencies. States upload traffic data to the FHWA through TMAS. Individual source files are combined programmatically into a single dataset. During this process, columns which are string type and have a fixed length are zero-padded and all integer columns are set to Int32. data is updated as deemed necessary Patrick Zhang Federal Highway Administration (FHWA) Transportation Specialist 202-366-1941 1200 New Jersey Ave. SE Washington DC 20590 United States patrick.zhang@dot.gov party that accepts accountability and responsability for the data and ensures appropriate care and maintenance of the resource
