| Summary: | Multi-airport system development is becoming a common solution to
capacity constraint problems in metropolitan areas around the world. GJMA, as
the biggest air transport market in Indonesia, have a plan to change their airport
system from a single airport system to a multi-airport system because of capacity
constraints. To relieve the congestion problem in the existing airport, an
expansion project and a new airport plan are being proposed by the government.
The new airport will be located in a greenfield site around a hilly area in the
Karawang Regency and plans to start operating in 2019.
The government has not yet decided on the roles of the airport, but only
proposed several scenarios to distribute the traffic for both airports. This study
aims to understand the configuration of the traffic distribution of the new multiairport
system environment in GJMA, using a five step strategic planning
methodology (CAIAD) which stands for Collect information, Analysing, Imaging,
Assessing and Deciding.
The results of the study show that the traffic distribution can lead to
implications on the existing and planned infrastructure, and also for the airport
users. The main implications are traffic volatility, underutilised airport
infrastructure, traffic demand that cannot be accommodated by the airports,
operational difficulty and poor service for the airport users. To minimise these
implications, the government should start planning the development of the new
airport based on flexibility related to the actual traffic demand and improved the
transport access facilities. This study also suggests two scenarios as options for
the government to implement in the GJMA multi-airport environment.
