Twenty-five airports have a connection with the local rail transit system, but each is unique. Variables such as network size, train frequency, type of airport station, time, and cost vary by airport. Both airport passengers and planners should have a technical basis of selecting which system is the most useful, efficient, and reliable. To date, there have been no scoring procedures created to rank the airports in order of quality of connection.
This thesis analyzes rail transit accessibility for all 25 airports (three of which have two separate transit systems) by investigating eight characteristics, three of which are market factors and five of which are system factors. The five system factors are travel time difference between car and train, transit cost difference between car and train, airport/transit connection type, network size, and train frequency. The three market factors are rail transit mode share, business traveler percentage, and low-cost carrier percentage.
Data from National Transit Database, combined with Department of Energy and Environmental Protection Agency information, examines impacts of automobile, truck, SUV, and public transportation travel on the production of greenhouse gas emissions.
In 2002, we examined trends in air service in the United States in the 12 months following the September 11 attacks. We found a steep and continuing drop in air travel, and an overall reduction in the number of flights supplied. Using the industry standard data base, the Official Airline Guide (OAG), we examined air service levels at individual airports, and ranked them by both flights reduced and reduced seat availability within three airport categories: large hub, small and medium hub and non-hub commercial service airports.
