System evaluation is discussed from the viewpoint of evaluating alternative engineering designs. the first chapter establishes the framework for evaluating alternative engineering designs and defines the major aspects of analysis which affect system evaluation. emphasis is placed on policy and judgmental issues and on system interactions which can significantly affect the measurement and level of system or project benefits and costs. the second chapter describes and compares four of the principal techniques of economic analysis and evaluation. the third chapter analyzes and evaluates three alternative highway projects to determine their economic feasibility in an absolute and relative sense. various economic analysis techniques are demonstrated and the requisite information for their use is detailed. every attempt was made to render the example problem realistic and to include all relevant aspects. this material was prepared as part of a more comprehensive traffic system planning text and serves to demonstrate use of principles which were outlined previously.
