Part Two of our interview: Sam Schwartz and T.O.P.P. founder & Executive Director Mark Gorton discuss how the modal split into NYC's Central Business District (essentially south of 59th Street) has changed over the last half century and how some of those numbers could easily be reversed by revoking free parking permits for NYC Governmental employees.

"Gridlock Sam" Schwartz served as NYC's Commissioner of Traffic from 1982-86 and is a former Chief Engineer/First Deputy Commissioner at the NYC DOT. He also writes a daily transportation column for the NY Daily News.
