Data for these years are not comparable to previous years.The FHWA estimates national trends by using State reported Highway Performance and Monitoring System (HPMS) data, fuel consumption data (MF-21 and MF-27), vehicle registration data (MV-1, MV-9, and MV-10), other data such as the R. L. Polk vehicle data, and a host <strong>of</strong> modeling techniques. Starting with the 2007VM-1, an enhanced methodology is used to provide timely indictors on both travel and travel behavior changes.From 1998-2006, the Federal Highway Administration (FHWA) used the Census Bureau's Vehicle Inventory and Use Survey (VI<strong>US</strong>) for its baseline estimate <strong>of</strong>combination trucks. Prior to 1998, the FHWA used the Census Bureau's 1992 <strong>Transportation</strong> Inventory and Use Survey (TI<strong>US</strong>) for its baseline estimates.Therefore, post-1997 data may not be comparable to 1997 and earlier years.In 1995, the U.S. <strong>Department</strong> <strong>of</strong> <strong>Transportation</strong>, Federal Highway Administration revised its vehicle categories beginning with 1993 data to include passengercars, other 2-axle 4-tire vehicles, single-unit 2-axle 6-tire or more trucks, and combination trucks. Pre-1993 data have been reassigned to the most appropriatecategory.SOURCES1965-94: U.S. <strong>Department</strong> <strong>of</strong> <strong>Transportation</strong>, Federal Highway Administration, Highway Statistics Summary to 1995, FHWA-PL-97-009 (Washington, DC: July1997), table VM-201A, available at http://www.fhwa.dot.gov/policyinformation/statistics.cfm as <strong>of</strong> Mar. 23, 2009.1995-2010: Ibid., Highway Statistics (Washington, DC: Annual issues), table VM-1, available at http://www.fhwa.dot.gov/policyinformation/statistics.cfm as <strong>of</strong> Mar.14, 2012.
