These graphs represent subsets of highway networks around the world.
They are generated daily for
the
Map-based
Educational Tools for Algorithm Learning (METAL) academic
project using highway data from the
Travel Mapping
Project. Details about graph data and the file formats are
here.
Contact
the METAL project leader with
questions or concerns, and please drop a note if you find these graphs and the related tools to be useful.
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.
You can download
a zip archive of
all of the latest graphs. Beware that this is a large file!
