A new methodology to improve delivery of emergency airport services is described. Important goals of airport response planning are to simultaneously maximize mobility and payload, and minimize arrival time. The Waterways Experiment Station of the US Army Corps of Engineers has developed the Army Mobility Model and Transportation Model. These models were adapted for use at airports by the US Department of Transportation Research and Special Programs Administration, Transportation Systems Center. A case study was performed that demonstrates that the airport-specific methodology can be used to assess and improve delivery of emergency services. Combining the two models with airport-specific geography creates a situation in which it is possible to quickly investigate travel time sensitivity to changes in factors such as weight, gear ratio, or tire pressure. This experience indicates that properly applied geographic colocation can lead to integration of transportation models with models from other fields.
