This is the repository of graphs generated from the current Travel Mapping Project data. These were created for use in the Map-based Educational Tools for Algorithm Learning (METAL) academic project. You may contact the author if you would like an archive of some or all of the graphs, or if you have special requests for a graph of specific subset of the project's data to be generated. If you do decide to make use of these graphs and/or the tools described here, please drop a note to the author.

For each graph, the table below gives a brief description, then download links and graph information for the default (collapsed), traveled, and simple formats. Note: larger graphs greatly tax the Highway Data Examiner and the Leaflet maps. They should all work, but large graphs require a lot of memory for your browser and some patience.

If you would like a local copy of all of the latest graphs, you can download a zip archive of all of them. Beware that this is a large file!

Graphs are copyright © James D. Teresco, generated from highway data gathered and maintained by Travel Mapping Project contributors. Graphs may be downloaded freely for academic use. Other use by explicit permission only.
