Abstract : The document describes optimization techniques applicable to the solution of the project addition network synthesis problem when descriptive traffic assignment models for establishing flow distribution patterns are employed. It describes the classes of models available for traffic assignment on transportation networks and outlines the types of improvements that may be considered. Project addition to an existing transportation network under a budgetary constraint is formulated as a discrete optimization problem which seeks to minimize the total users' cost. Two optimization techniques are then developed to solve the synthesis problem, which use descriptive traffic assignments throughout the solution procedures. (Author)
