Transportation Network Analysis

Stephen D. Boyles, Nicholas E. Lownes, and Avinash Unnikrishnan


This site hosts the current version of the Transportation Network Analysis textbook. The first edition was released in January 2025 after several years of "public beta" feedback. We plan to periodically update the text, and would be grateful for any assistance you can provide, whether spotting typos, math or logic errors, inconsistent terminology, or other suggestions for improving the explanations, organization, or presentation of the content.

Currently, one volume is available, covering static and dynamic traffic assignment. A second volume, covering transit, freight, and logistics, is under preparation. Both volumes will always be available free-of-charge from this site as PDF files.

We will shortly provide a link to a low-cost physical version of the text. In the coming months, we will also aim to provide supplementary materials for instructors, including slides, assignments, and solutions. In the meantime, if you are an instructor considering these materials for use in your course, please contact me at sboyles@austin.utexas.edu, and I can share preliminary versions of some of these materials.

We gratefully acknowledge the support of the National Science Foundation in preparing this text, under Grants 1069141/1157294, 1254921, 1562109/1562291, 1636154, 1739964, and 1826320. Thanks are also due to Travis Waller (University of New South Wales) and Chris Tampère (Katholieke Universiteit Leuven) for hosting visits by the first author to their respective institutions, and for providing wonderful work environments where much of this writing was done. We also acknowledge the help many colleagues and students have provided in noticing errors in earlier drafts and suggesting improvements.
