Abstract

In traditional four-step travel demand forecasting, trip generation modeling is the first
analytic process undertaken to determine travel demand in terms of trip rates or total
trips. As trip generation is the first stage of the modeling process, errors here are carried
through the entire process and may invalidate work on subsequent stages. The American
travel survey (ATS), conducted by the bureau of transportation statistics (BTS) in 1995
represents a database of long distance passenger travel information collected by the
federal government. It served as the primary data source for this investigation. The main
objective of this paper is to develop a simple long distance trip generation model for
metropolitan areas. Effect of metropolitan income on the total number of generated trips
is also incorporated in this study. The presented model can be calibrated and used
outside the states.
