This paper presents the findings of an exploratory analysis of the data collected in this test. The clustering of the day patterns from the FMS data revealed a large day-to-day variability of user behavior that could not be captured by a snapshot with a 1-day survey. Even the high cross-sectional variability from the larger sample size of a traditional survey would not have achieved the comprehensive set of heterogeneous patterns provided by FMS. Some common problems in traditional surveys\u2014such as the underreporting of trips, the overestimation of travel times, and the inaccuracy of locations and times\u2014can apparently be reduced by FMS. The FMS data have higher resolution and better accuracy compared with the HITS data. In addition, FMS is well suited to the collection of multiday data because additional costs are marginal and the user burden decreases over time. FMS offers a promising technology for the next generation of travel data collection. <\/jats:p>","DOI":"10.3141\/2494-06","type":"journal-article","created":{"date-parts":[[2016,1,5]],"date-time":"2016-01-05T19:31:06Z","timestamp":1452022266000},"page":"45-56","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":80,"title":["Exploratory Analysis of a Smartphone-Based Travel Survey in Singapore"],"prefix":"10.1177","volume":"2494","author":[{"given":"Fang","family":"Zhao","sequence":"first","affiliation":[{"name":"Future Urban Mobility, Singapore\u2013Massachusetts Institute of Technology Alliance for Research and Technology, 09-01\/02 Create Tower, and 1 Create Way, Singapore 138602"}]},{"given":"Francisco C\u00e2mara","family":"Pereira","sequence":"additional","affiliation":[{"name":"Future Urban Mobility, Singapore\u2013Massachusetts Institute of Technology Alliance for Research and Technology, 09-01\/02 Create Tower, and 1 Create Way, Singapore 138602"}]},{"given":"Rudi","family":"Ball","sequence":"additional","affiliation":[{"name":"Future Urban Mobility, Singapore\u2013Massachusetts Institute of Technology Alliance for Research and Technology, 09-01\/02 Create Tower, and 1 Create Way, Singapore 138602"}]},{"given":"Youngsung","family":"Kim","sequence":"additional","affiliation":[{"name":"Future Urban Mobility, Singapore\u2013Massachusetts Institute of Technology Alliance for Research and Technology, 09-01\/02 Create Tower, and 1 Create Way, Singapore 138602"}]},{"given":"Yafei","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Urban Studies and Planning, Room 10-403, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139."}]},{"given":"Christopher","family":"Zegras","sequence":"additional","affiliation":[{"name":"Department of Urban Studies and Planning, Room 10-403, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139."}]},{"given":"Moshe","family":"Ben-Akiva","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, Room 1-181, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139."}]}],"member":"179","published-online":{"date-parts":[[2019,4,28]]},"reference":[{"key":"bibr1-2494-06","doi-asserted-by":"publisher","DOI":"10.1016\/j.tra.2010.08.004"},{"issue":"3","key":"bibr2-2494-06","doi-asserted-by":"crossref","first-page":"245","DOI":"10.3328\/TL.2009.01.03.245-255","volume":"1","author":"Auld J.","year":"2009","journal-title":"Journal of Transportation Letters: The International Journal of Transportation Research"},{"key":"bibr3-2494-06","doi-asserted-by":"publisher","DOI":"10.1177\/0361198106197200102"},{"key":"bibr4-2494-06","doi-asserted-by":"publisher","DOI":"10.1016\/j.trc.2008.11.004"},{"key":"bibr5-2494-06","doi-asserted-by":"publisher","DOI":"10.1007\/s11116-007-9126-8"},{"key":"bibr6-2494-06","doi-asserted-by":"publisher","DOI":"10.3141\/2246-03"},{"key":"bibr7-2494-06","unstructured":"StopherP., and WargelinL.
