Book Description

A comprehensive model of statewide transportation flows that is sensitive to the quality and capacity of the transportation network can be a valuable tool for programming investments in highways, airports, and intermodal transfer facilities. However, most planning models were developed to address the needs of a single mode and do not incorporate the feedback effects on the larger economy resulting from these investments. Phase I of this project outlined the elements of a conceptual model for statewide transportation flows. Issues addressed in Phase I included transportation demand forecasting methodologies, modal split and network assignment procedures, social welfare impact measurement and distribution, economic feedback analysis, and database requirements and structure. The purposes of this report (Phase II of the project) are to specify in mathematical form the individual modules of the conceptual model developed in Phase I, to identify and evaluate sources of data for the model set, and to develop the transport networks necessary to support the models.
