Ground Access Trip Generation Models for Airport Planning

The geographical distribution of air passenger trip origins forms a critical input to studies of airport ground access and airport choice. This paper discusses the limitations of typical air passenger surveys to determine the distribution of air passenger trip origins at a required level of resolution, the resulting need for air passenger trip generation models, and considerations that arise in developing such models. The paper then presents a set of air passenger trip generation models that were developed to support the current update of the Bay Area Regional Airport System Plan Analysis and discusses their strengths and limitations. The paper concludes by discussing the need for additional analysis to improve the future utility of the models and the potential transferability of these models to other regions.
