The primary objective of the research upon which this report is based was to develop a model which would permit the efficient exploration of a wide range of policies regarding intercity transportation service and their implication for future transportation system investment and operations. There were two major thrusts to the research. One was to develop the components of a computer model which would synthesize transportation investment programs which meet policy objectives. This set of sub-models consists of a graph generator, designed to generate a wide range of transportation system link and mode investment alternatives, a multiple-mode network operations model, which identifies the most efficient manner in which to operate any given network of links and modes, and an investment staging model, which identifies the optimal sequence of investments. A major feature of these models is that the costs and travel demand on each mode is a function of the quality and quantity of service offered, and the effects of one mode upon another are directly considered. The second thrust of the effort was to attempt to define operational measures of policy. One outcome of this research was a comparison of the quality of services for all city pairs in the Northeast Corridor for 1940, 1950, 1960, and 1965, and an identification of cities which are poorly served.
