Public transit ridership in the United States rose 1 percent to 10.8 billion trips in 2014, the highest level in 58 years, the American Public Transportation Association said Monday.

Subway and train ridership was up by 3 percent, while bus ridership was down about 1 percent. The total transit ridership was the highest since 1956, when ridership was 11.0 billion.

The trade group's president, Michael Melaniphy, attributed the increase to the nation's improving economy and to increasing transit options in many cities.
