Abstract:U.S. residents across many regions continue to face episodes of poor air quality due in part to pollution and emissions from the transportation sector. Strategies to encourage travel behavior changes and reduced driving during such events may or may not be effective. To illuminate how area-wide air pollution affects traveler behaviors and to better understand the potential for travel behavior change strategies, we developed a multi-phase longitudinal (travel) survey data collection effort in Cache County, Utah, involving an initial survey about personal and household characteristics, a series of three two-day travel diary surveys during winter 2019, and a final survey about perceptions. We then analyzed the resulting data. First, we studied how measured (or perceived) poor air quality affected individuals’ daily travel amounts, finding little change in trip frequencies or total travel times. We did find that respondents were mostly aware of when air pollution levels were elevated. Second, we studied the degree to which people attributed the responsibility for air pollution to themselves or others, finding three groups of people differentiated by various travel, perceptual, and personal characteristics. People assuming more responsibility reported more travel behavior changes. Third, we analyzed 20 different activity and travel outcomes (taken from the travel diary surveys) for associations with air quality, while controlling for personal/household characteristics and neighborhood type. We found some “altruistic” travel behavior changes in response to air pollution, as well as differences for urban vs. suburban/rural residents. More research on these topics is needed in different urban areas.
The total size of the zip file is 2.3 MB. The .r file type is related to R programming language. R is a language and environment for statistical computing and graphics (for more information on .r files and software, please visit https://www.file-extensions.org/r-file-extension). The .docx file is a Microsoft Word file, which can be opened with Word and other free word processor programs, such as Kingsoft Writer, OpenOffice Writer, Apache OpenOffice, and ONLYOFFICE. The .txt file type is a common text file, which can be opened with a basic text editor. The most common software used to open .txt files are Microsoft Windows Notepad, Sublime Text, Atom, and TextEdit (for more information on .txt files and software, please visit https://www.file-extensions.org/txt-file-extension). The .xlsx and .xls file types are Microsoft Excel files, which can be opened with Excel, and other free available spreadsheet software, such as OpenRefine. The Portable Document Format (PDF) file format was developed by Adobe Systems and represents two-dimensional documents in a device-independent and resolution-independent format. There are PDF readers available on many platforms, such as Xpdf, Foxit, and Adobe's own Adobe Acrobat Reader. PDF readers/viewers or online services for basic functions are generally free (for more information on .pdf files and software, please visit https://www.file-extensions.org/pdf-file-extension). The .csv, Comma Separated Value, file is a simple format that is designed for a database table and supported by many applications. The .csv file is often used for moving tabular data between two different computer programs, due to its open format. The most common software used to open .csv files are Microsoft Excel and RecordEditor, (for more information on .csv files and software, please visit https://www.file-extensions.org/csv-file-extension). The file extension .md is among others related to texts and source codes in Markdown markup language. Markdown is a lightweight markup language, to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML) (for more information on .md files and software, please visit https://www.file-extensions.org/md-file-extension).
