The report shows a record increase nationally in public transportation use in 2013. Americans took more than 10 billion trips by bus, train, or subway, which is the highest total since 1956.
Los Angeles was second to New York City in ridership gain in 2013, according to the report. New York City accounted for one in three trips nationally, while Los Angeles made up more than 9 million.
The New York City-New Jersey transit was next, followed by Seattle and Miami.
Experts say the nation's urban shift, along with economic recovery in certain areas, helped the increase.
