For bus users I think that informative bus signs would be helpful. Having to research ahead of time what number is needed is just plain dumb.
The image posted is at the extreme end of the spectrum but it certainly made getting around the city quite easy. Every stop on the bus route is listed on that sign and the signs are at every stop along the routes.
Right now the bus stop signs are pretty much useless.
While on the topic, an interactive website would be a plus as well. Plug in your departure point and destination and it spits out all the combinations - really should not be that difficult to do. Perhaps I was looking in the wrong spot but when I looked for routes on the site I got a pdf.
