San Francisco/Bay Area Public Transport
LA should copy the http://www.511.org/ website. It has all the information one could need about time tables and getting from one place to another on multiple forms of public transport. It certainly has helped me get around the Bay Area easily and with a lot less searching than the system in LA.
On the other hand, the BART trains are extremely noisy. I don’t recall going on trains that are noisier than the BART trains. I got used to it, and the wide seats made up for the loud sound, but it is an area of potential improvement.
