Several years back Waterloo, Ontario, Canada, started discussing the installation of a light rail transit system. Snapsort, a tech company based on that community, supported that proposal and came up with this infographic to help educate people about light rail transit. It's a good example of how agencies can use infographics to educate the public about proposed projects.
(If you want to learn more about the project, you can check out the Region of Waterloo's Rapid Transit Website.)
