Metro's proposal to raise riders' fares starting on July 1 will further erode ridership, according to the agency's own figures.
The agency estimates that ridership on the rail system would drop 1 percent under the increase, Metro spokesman Dan Stessel said, and fall 1.3 percent on the bus system. Fare hikes typically drive down ridership, but transit agencies make up for the loss with the additional fare from the hike.
However, this would come on top of additional losses. Metrorail ridership has been wavering since 2009, even as other subway systems have seen recent increases.
Metro had already forecasted a continuing drop on the rail system, with a fall of 3 percent expected in the next year, even without a fare increase.
