"Nationwide, public transportation accounts for only about 2% of all motorized trips, according to data provided by Dr. Alain Kornhauser in his presentation to WNAC. And about 1/2 of the peak commute trips are in the NYC metro area. With this kind of utilization, Kornhauser states that the current state of public transportation is a metaphorical train wreck.
"And, as would be expected, data from a SPUR white paper suggests that public transportation in Santa Clara County underperforms compared to comparable areas (San Diego with a similar density has 39% fare recovery compared to Santa Clara County’s VTA with 12% fare box recovery http://www.spur.org/publications/article/2010-08-01/transit-valley)."
