Abstract:This report describes how two operations research decision making tools, Multicriteria Decision Making (MCDM) and Risk Analysis (RS), may be used in conjunction with transportation system modeling techniques to select amongst alternative transportation corridor improvement options. Each corridor improvement option is defined to have certain consequences with respect to the decision maker's goals. The measures of the consequences are estimated or forecast by the FTA four-step modeling process and by traffic simulations using NETSIM. Air quality measures are estimated using MOBILE5a. Uncertainty in the future operating environment is also included in the procedure. The procedure is demonstrated through a simple hypothetical application in which two alternatives are compared. The example shows that the concepts involved are relatively easy to learn and use. Off-the-shelf software, which is available to implement these tools, provides useful sensitivity analysis features which are discussed as part of this report,
