Abstract:

The Parkway Corridor is the primary ground facility at the Dallas/Fort Worth (D/FW) International Airport. It consists of an expressway for passengers to-and-from terminals and a service road mainly for employees of airline-associated agencies to access the service areas. As the Parkway Corridor is a natural short cut in the region, it has attracted more and more through commuters who usually choose to use the service road so as to circumvent the toll plazas on the expressway. The dramatic increase in both the volume and speed of through commuting traffic in recent years not only impedes service activities, but also raises safety concerns. The D/FW Airport Board is considering the installation of a series of traffic signals to regulate the cruise speed and thereby discourage use of the service road by commuters. This research is conducted to evaluate its effectiveness and potential impact on traffic patterns along the Parkway Corridor. A systematic approach, integrating queueing theories (G/M/m), discrete models, and traffic assignment, is proposed in this research, which allows the user to project the traffic distribution on each route with only the information obtained by traffic counts. Numerical results of alternate control strategies and a sensitivity analysis with respect to key parameters, such as the toll and cycle length of traffic signals are also reported.
