Abstract:Efficient and fair transportation planning creates opportunities and equity for jobs, health care, and education. Therefore, data consolidation for transportation systems provides basis for evidence based policies. In this work, we construct a dataset that documents home-to-job commuting time and distance information for the 100 most populated U.S. urban areas. Our dataset builds on the U.S. Census Bureau's Longitudinal Employer-Household Dynamics Dataset, which provides origin (home) and destination (job) location information for households. For these origin-destination (OD) pairs, we derive commuting time and distance information under different travel modes, each a combination of walking, public transit, and ridesourcing. We construct data under different modes so policymakers and researchers have information about alternatives and can perform what-if analysis. Towards the end of this data sheet, we document a sample use case to illustrate this goal.
The total size of the described zip file is 29.85KB. The ZIP file for this dataset contains files with the following file extensions: The .csv, Comma Separated Value, file is a simple format that is designed for a database table and supported by many applications. CSV files can be viewed in a spreadsheet software such as Excel or in a text file reader such as Notepad. PDF files can be view in the default web browser or any PDF software. MD files can be view in any text document reader, such as Notepad. Gitkeep files are used so that empty folders will be tracked via GIT and file structures will be retained even when the folders contain no files (for more information on .gitkeep files and software, please visit https://www.file-extensions.org/gitignore-file-extension).
