Metropolitan Travel Survey Archive : ウィキペディア英語版 | 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.〔 Archived from the (original ) on May 1, 2009.〕 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.
