Transportation Networks is a networks repository for transportation research.
If you are developing algorithms in this field, you probably asked yourself
more than once: where can I get good data? The purpose of this site is to
provide an answer for this question! This site currently contains several examples
for the traffic assignment problem. Suggestions and additional data are always welcome.
Many of these networks are for studying the Traffic Assignment Problem, which is one of the most
basic problems in transportation research. Theoretical background can be found in
“The Traffic Assignment Problem – Models and Methods” by Michael Patriksson, VSP 1994,
as well as in many other references.
This repository is an update to Dr. Hillel Bar-Gera’s TNTP.
As of May 1, 2016, data updates will be made only here, and not in the original website.
Each individual network and related files is stored in a separate folder. There
are a number of ways to download the networks and related files:
- Click on a file, click view as Raw, and then save the file
- Clone the repository to your computer using the repository’s clone URL. This is done with a Git
tool such as TortoiseGit. Cloning will download the
entire repository to your computer.
There are two ways to add a network:
- Fork the repo
- Create a GitHub account if needed
- Fork (copy) the repo to your account
- Make changes such as adding a new folder and committing your data
- Issue a pull request for us to review the changes and to merge your changes into the master
- Create an issue, which will notify us. We will then reply to coordinate adding your network to the site.
Make sure to create a README in Markdown for your
addition as well. Take a look at some of the existing README files in the existing network folders to see what
