From a frequent commenter:
I was thinking about transit websites, and I had a thought that struck me with how blindingly obvious it is, and I'm surprised for some reason I don't think I've seen any transit agency do this before. On the main timetable page, they will generally have a menu to let you pick a route, and give you the timetable and map for that route. But those are leaf pages, they don't link to anything other than back to the menu. My thought is, the web is all about links, so why not make the structure of the timetable pages reflect that of the route network, and for any route to which there's a transfer, provide a link to that route's timetable right there on the page? With fancy web design, I'm sure even more elaborate things can be made, like letting you see what transfers you can make for a particular run of a route. But in general, this seems like one of those things that can greatly enhance the public's understanding of how the transit network works, and I'm surprised that I don't recall seeing this anywhere before.
If you know of a transit agency that does this, please comment with a link to a sample timetable page!
