Abstract:

The major objective of this paper is to demonstrate a methodological approach to estimating the pattern of long-distance highway travel demand (between large metropolitan areas), using data from the 1995 American Travel Survey (ATS). The objective is not to develop a final model for estimating intercity travel demand. It is rather to obtain an understanding of the types of costs that travelers consider in making long-distance destination choices as well as the nature of the statistical challenges that arise in estimating such demand using the ATS data. The approach used leads to several important by-products. Foremost is the development of an approach that brings the estimation of intercity travel demand by small area into the mainstream of travel demand modeling. Second, it enables estimating the changes in demand for travel between cities as a result of changes in costs of travel between cities. Further, the observed flow table [which gives the sampled counts of trips between each origin-destination (O-D) metropolitan area] is likely to be "jagged" in the sense that a number of O-D pairs may have zero counts, whereas others have large counts. The process allows the smoothing of the observed intercity flow table, which is important for the ultimate purpose of prediction (prediction in not considered in this paper). The paper is organized as follows: Following an introduction, the authors briefly describe the data used. Next they describe the model proposed and the procedures used to estimate model parameters in the section on Gravity Model of Inter-City Flows. The special considerations that arise in using the ATS for demand models are described in the section on Unique Characteristics of the ATS. The authors present different scenarios for intercity travel demand and the scenario estimation results in the section on Scenarios Evaluated and Results. The final section presents the authors' conclusions.
