These observations are all common sense, but they've been made official in a report released last week by the San Francisco's Planning and Urban Research Association. The report (which, according to Bay Area Transit News, is a 7 meg PDF that only contains 60k of text -- talk about inefficient!) details the problems (basically, that Muni sucks) the consequences facing SF if we can't get ridership to increase (more cars, less development, more fare increases), and a bunch of solutions, which is fortunate, since Muni doesn't seem capable of figuring out how to behave on its own.
To spare you from having to download the PDF, we've collected some of the report's main highlights here, and summarized them. With pictures!
