BART is taking public comments on a plan to increase current fares by 3.4 percent next year, transit agency officials said.
Starting on Jan. 1, 2016, fares will increase by either 10 or 15 cents, depending on the distance of the trip.
Passengers who travel between Berkeley and MacArthur stations or from the El Cerrito del Norte to 12th Street Oakland City Center stations will see a 10-cent hike.
It will cost 15 more cents to ride along longer stretches of the system, including from Hayward to Embarcadero, from Lake Merritt to Balboa Park and from Walnut Creek to Powell Street.
The added revenue from the fare hike will help pay for high-priority projects in the transit system, including new rail cars, an automated train control system and an expansion of the Hayward Maintenance Complex, BART officials said.
