A description and results are presented of a study to locate and design rapid runway exits under realistic airport conditions. The study developed a PC-based computer simulation-optimization program called REDIM runway exit design interactive model to help future airport designers and planners to locate optimal exits under various airport conditions. The model addresses three sets of problems typically arising during runway exit design evaluations. These are the evaluation of existing runway configurations, addition of new rapid runway turnoffs and the design of new runway facilities. The model is highly interactive and allows a quick estimation of the expected value of runway occupancy time. Aircraft populations and airport environmental conditions are among the multiple inputs to the model to execute a viable runway location and geometric design solution. The results presented in the report suggest that possible reductions on runway occupancy time ROT can be achieved with the use of optimally tailored rapid runway designs for a given aircraft population. Reductions of up to 9-6 seconds are possible with the implementation of 30 msec. variable geometry exits.
