# Transportation Networks
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](http://www.bgu.ac.il/~bargera/tntp).
As of May 1, 2016, data updates will be made only here, and not in the original website.
# How To Download Networks
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](https://tortoisegit.org). Cloning will download the
entire repository to your computer.
# How To Add Networks
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](https://guides.github.com/features/mastering-markdown) for your
addition as well. Take a look at some of the existing README files in the existing network folders to see what
is expected.

# Formats
Any documented text-based format is acceptable. Please include a README.MD that describes the files,
conventions, fields names, etc. It is best to use formats that can be easily read in with technologies
like R, Python, etc. Many of the datasets on TransportationNetworks are in TNTP format.
## TNTP Data format
TNTP is tab delimited text files, with each row terminated by a semicolon. The files have the following format:
- First lines are metadata; each item has a description. An important one is the ``.
In the some networks (like Sioux-Falls) it is equal to 1, indicating
that traffic can move through all nodes, including zones. In other networks when traffic is not
allow to go through zones, the zones are numbered 1 to n and the `` is set to n+1.
- Comment lines start with ‘~’.
- Network files (must be named `_net.tntp`) – one line per link; links are directional, going from “init node” to “term node”.
- Link travel time = free flow time * ( 1 + B * (flow/capacity)^Power ).
- Link generalized cost = Link travel time + toll_factor * toll + distance_factor * distance
- The network files also contain a "speed" value for each link. In some cases the "speed" values
are consistent with the free flow times, in other cases they represent posted speed limits, and
in some cases there is no clear knowledge about their meaning. All of the results reported below
are based only on free flow travel times as described by the functions above, and do not use the speed values.
- The standard order of the fields in the network files is:
- Init node
- Term node
- Capacity
- Length
- Free Flow Time
- B
- Power
- Speed limit
- Toll
- Link Type
- Trip tables (must be named `_trips.tntp`) – An Origin label and then Origin node number, followed by Destination node numbers and OD flow
```
Origin origin#
destination# , OD flow ; …..
```
