In this study, we used the rounding error in reported trip departure/arrival times to measure quality deterioration due to proxy responses in a travel survey. In self-reported travel surveys, the trip departure/arrival times are often reported as rounded values, such as those ending in 00, 10, 15, 30, and 45 min. We hypothesized that, compared to self-response, proxy response often contains more rounded departure/arrival times. Data from the 2017 US National Household Travel Survey were used to analyze the demographic characteristics and effects of proxy responses. A descriptive analysis revealed that males in their 20s–50s tended to be proxy respondents, whereas males in their 50s or older tended to be proxy completers. Proxy-reported discretionary trips were often misreported, and proxy responses often contained rounded departure/arrival times. To control the effects of demographic variables, we finally estimated a binary logit model to describe the relationships among the self- and proxy response choices, demographic attributes of the respondents, and rounding in the reported times The results revealed a statistically significant association between proxy response and rounded reported time, supporting our hypothesis.","PeriodicalId":311811,"journal":{"name":"Journal of JSCE","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135057589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
