The acceptance rate of a runway at an airport can be considerably increased by proper location of high-speed exit taxiways along the runway downrange. The location, geometry and the exit angle of these high-speed exit taxiways play a crucial role in the successful negotiation of the turnoff and in reducing the runway occupancy times. This reduction in ROT increases the acceptance rate of a runway and thereby increasing the capacity of the airport. Research was done to approximate the radius of curvature with the aid of a compound curve rather than a single curve for the exit taxiway.

In the past studies, researchers did not lay much emphasis on the presentation of the results of the model developed. This project has been envisioned to present the output provided by the “Runway Exit Design Interactive Model” to the analyst in such a manner that improvement, analysis and the design of a new runway can be done with the aid of interactive screens provided in the output phase. The analyst may perform sensitivity analysis, compare the centerline turnoff geometries and view the change in runway occupancy times for each aircraft, for different turnoffs and for different runway surface conditions.

A general description of the model, the output interface and the exit taxiway geometry built with a compound curve is also included.
