Also in 2001, heavy-rail pmt totaled 14.2 billion or 31 percent, commuter rail reached 9.5 billion pmt or 20 percent, light rail had 1.4 billion pmt or 3 percent, and other modes of transit, such as ferryboat and demand responsive,1 generated 1.8 billion pmt or 4 percent .
The top 30 transit authorities (ranked by unlinked passenger trips) logged 35.1 billion passenger-miles in 2001 or 76 percent of all transit pmt that year . In 2001, people riding New York City Transit traveled 10.1 billion passenger-miles (or 22 percent of all passenger-miles out of the top 30 authorities) and the Chicago Transit Authority generated 1.8 billion pmt or 5 percent .
