The ground access system at Singapore Changi Airport is analyzed. The emphasis is on understanding traffic characteristics and utilization of access facilities. The applicability of typical ground access planning parameters recommended for western airports to Changi Airport is also investigated. Peak traffic levels are found to be manageable. The curbside is the critical link of the access system but congestion in peak periods do not last very long at present. Although the two public car parks together provide enough parking spaces, the closer-in car park is always full in the evening, while the cheaper car park is usually half empty even though it is only 250 m farther. This suggests convenience is more important than cost to most users.
