This video from Streetfilms looks at how the bus stop consolidation could ease bus traffic in San Francisco, but touches on the political fires the idea can start.
"Muni's stops are actually much closer than its own standards advise. Only 17 percent of Muni's bus stops fall within the recommended range of 800-1,000 feet (closer on steep hills); 70 percent are closer than that. As SFMTA staff has pointed out in the past, nationwide research shows most people are willing to walk a quarter-mile to the nearest bus stop.
The SFMTA's first attempt to consolidate stops -- a pilot project on the 38-Geary in the Tenderloin -- turned out poorly for the agency."
