If ANY web site should have a mobile-friendly layout that automatically loads when accessed by a mobile device, it’s public transit sites.
Seriously — people want to use transit sites on the go! That’s kind of the whole point of transit.
My local transit agency is RTD Denver. Go check out that site. It’s hard enough to navigate on a computer with a big display and a real keyboard. Just try it on your phone! Torture!
And if they offer a mobile version, they sure don’t make that obvious.
Got some especially good examples of mobile-friendly public transit sites? Give your examples in the comments.
