Metropolitan Travel Survey Archive
The U.S. Metropolitan Travel Survey Archive is a project to store, preserve, and make publicly available, via the internet, travel surveys conducted by metropolitan areas, states and localities.
As of 2007, the archive held 58 surveys comprising 2,718,329 trip records, 516,108 person records, 219,097 household records, 173,354 vehicle records, and 528,847 location records.<ref name=TMIPConnection2007 /> Similar to this U.S. archive, an international archive of travel survey date has been suggested so that this service is expanded into more countries.<ref>Template:Cite book</ref>
The motivation behind the archive is to forestall the loss of electronic files and documentation of surveys, which has befallen previous surveys.<ref name=TMIPConnection2007>Template:Cite journal Archived from the original on May 1, 2009. "Properly archiving the travel surveys at a central location (with remote backups) safeguards the data against loss to calamities such as fires, earthquakes, floods, and terrorist attacks that have befallen earlier surveys."</ref> These surveys are both costly to conduct, and irreplaceable as it is impossible to reconstruct past records of human travel behavior.<ref>Metropolitan Travel Survey Archive Available as Off-Site Archive in Urban Transportation Monitor Volume 19, No. 20, pp.1,9 Nov. 11, 2005 Template:Webarchive</ref> The archive was established with funding from the United States Department of Transportation.<ref>Template:Cite web</ref>
