Abstract:The Volpe Center first estimated an inter-regional auto trip model as part of its effort to assess the market feasibility of maglev for the National Maglev Initiative (NMI). The original intent was to develop a direct demand model for estimating inter-regional auto trips which could be used with a set of diversion models that were being developed by Charles River Associates.
To apply the diversion models (and estimate travel demand for a new mode), base year and future year estimates of person trips, by mode, are necessary. Base year estimates of person trips are readily available for two of the three major modes of inter-city travel. Air trips are available from the U.S. DOT's (RSPA) 10% ticket sample; and rail trips can be obtained from AMTRAK. However, since no nationwide data base exists that can provide estimates of auto trips between city pairs, Volpe Center staff proceeded with the development of an econometric model for accomplishing this. Over the past year, the Volpe Center's NMI auto model has been reviewed and updated. With each update, the statistical robustness has improved.
The succeeding section describe steps that were taken to update the model.
