Taiwan Taoyuan International Airport is reportedly planning to construct a smaller terminal, to help meet the increasing passenger demand at the airport.

Taiwan Minister of Transportation and Communications Chen Chien-yu confirmed the plans and said that a smaller Terminal 4 will be built before the completion of Terminal 3.

The Taoyuan International Airport Corporation Ltd. (TIAC) had already briefed the Ministry of Transportation and Communications and the executive Yuan about its preliminary plan and details of the project, according to Chien-yu.

The proposed Terminal 4, which could be built on the space occupied by Terminal One’s parking lot, is expected to be equipped with automatic check-in counters and automatically adjusted light and air conditioning.

Upon completion, it is expected to accommodate five million passengers.

The airport’s two existing terminals, which serviced 35 million passengers in 2014, have the capacity to serve only 32 million visitors annually.

More than 40 million passengers are expected to arrive at the airport this year, necessitating the requirement for additional facilities at the airport.

Construction of Terminal 3 is currently in progress and is expected to be completed by 2020.

In addition, a project to expand the area of Terminal 2 has also been proposed which is scheduled to be completed in 2017.

TIAC expects to increase total capacity to support 86 million visitors by 2042 and about 80 million annual passengers by 2040.

According to Airport Council International (ACI), Taiwan Taoyuan International Airport was the world’s 11th busiest airport in terms of passengers and fifth in terms of international freight traffic.
