The cities are derived from the Census's "Cities with 100,000 or More Population in 2000" . US cities only for now, though I'd love to hear about Chinatown buses on other continents, if such a thing exists! Some destinations ocassionally appear with their Mandarin equivalents.
The "Download" feature is extremely experimental. Should work with Safari, Chrome and Firefox. Built with D3.js . Code on Github.
Questions? crucial destination missing? supplemental Mandarin translations? please email me (Jeff Sisson) .
