Abstract

The model developed by this research uses impirically determined relations between total travel and regional socioeconomic activity as the basis for estimating the pattern of intercity travel by all modes. Origin-destination surveys of both intercity highway traffic and air passenger traffic together with census data provide the basis for determining these relations. A comparison of costs for air travel versus surface travel between each pair of communities within the study area provides the basis for estimating the modal split. Comparisons of estimated air travel and observed air travel for all texas cities with commercial air passenger service in 1967 indicate that the model provides reasonable estimates of air passenger travel generated by individual communities. Although discrepancies between estimated and observed volumes do exist and future refinelment of the model may be warranted, it is recognized that the potential demand for air travel is not the only factor used in resource allocation decisions. Social, political, and economic factors will unquestionably continue to influence decisions concerning the development of the air transportation system.
