description: The Oak Ridge Commodity Flow dataset is from the Oak Ridge National Laboratory (ORNL), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics’ (BTS’) National Transportation Atlas Database (NTAD). The Oak Ridge Highway Planning Network is a database of major highways in the United States. It is a foundation for analytic studies of highway performance, for vehicle routing and scheduling problems, and for mapping purposes. The network is based on a set of roadways digitized from the National Atlas by the U.S. Geological Survey. It has been enhanced at Oak Ridge National Laboratory by adding additional roads and attribute detail and correcting topological errors to produce a true analytic network.  This documentation is intended primarily to assist users of this database by describing its structure, data elements, and development.

The 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 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). File extension .json is associated to JavaScript Object Notation file format, a lightweight, text-based, language-independent data interchange format. JSON defines a small set of formatting rules for the portable representation of structured data. It is used by various applications as alternative option to XML file format. The data in a json file are stored in simple text file format and the content is viewable in any simple text editor (for more information on .json files and software, please visit https://www.file-extensions.org/json-file-extension).
