Integration of Transit Systems at Seattle-Tacoma International Airport

摘要

Increasingly, large-hub airports in the United States are becoming intermodal terminals connecting people to a diverse range of transportation modes. In most U.S. large-hub airports, the percentage of passengers accessing airports by mass transit is relatively small as these systems are primarily used by employees. This will likely change in the next 10 to 20 years at airports located in urban areas due to regional roadway congestion, emissions concerns, and rise in fuel prices. Over the last decade, Seattle-Tacoma International Airport (SEA) has prepared several studies for integration of transit systems for light rail, automated transit using PRT (personal rapid transit) technology and people mover (APM), and bus transit. This paper is a case study on the challenges of integrating these transit systems into Seattle-Tacoma International Airport shown in Figure 1. It explores issues related to: various types of transit systems, facility requirements, existing airport constraints, security, and environment.
