BEIJING, Jan. 16 (Xinhua) -- Beijing subway will soon offer passengers more ticket options, with the one-day pass the first to be launched, according to the municipal commission of transportation.

The one-day pass, valid for 24 hours of unlimited metro travel, will be convenient for visitors to Beijing and help boost tourism, the commission was quoted by Wednesday's China Daily as saying.

The capital now uses a metered fare system for subways. Passengers can buy single-ride tickets or use a rechargeable card.

The city also plans to accelerate construction of three subway lines this year and will open three including the line connecting the new Beijing Daxing International Airport with the downtown district, the transportation commission said.

Authorities also said they will ease the transfer from subways to buses by integrating the two fare systems.
