The airport currently has no automated people mover (APM) available and only has one bus that can be used to transport passengers to the satellite terminal. Airport sponsors have left you with the final decision: invest in a state of the art APM system, which will connect the entire airport via a train system, or investing in buses to move people to and from the satellite terminal. The APM project is estimated to cost 1.2 billion dollars and will take 3 years to complete, while integrating electric buses will cost $1.1 million dollars per bus, not including employee wages, and can be operated in 3 months time.
