Friday, July 17, 2009 - The U.S. Department of Transportation's Bureau of Transportation Statistics, a part of the Research and Innovative Technology Administration, released the 2009 edition of the National Transportation Atlas Database (NTAD) this week. The 2009 edition features 10 updated datasets from last year's NTAD and premieres the Federal Highway Administration's Highway Performance Monitoring System (HPMS). Also, substantial revisions were made to national parks, waterways, National Bridge Inventory and railways. This year's NTAD consists of 28 datasets. The NTAD also includes: intermodal terminals, national railway crossings, non-attainment areas and transit rail lines and stations, among other data layers. NTAD 2009 is provided in shapefile format, which is compatible with most Geographical Information Systems (GIS) software. Following the initial release earlier this week, BTS staff distributed copies of the 2009 NTAD to attendees of the ESRI International User Conference in San Diego.
