EVALUATION OF ALTERNATIVES USING THE SURFACE TRANSPORTATION EFFICIENCY ANALYSIS MODEL (STEAM)

The Intermodal Surface Transportation Efficiency Act (ISTEA) and its successor, the Transportation Equity Act for the 21st Century (TEA-21), both emphasize assessment of multimodal alternatives and demand management strategies. This emphasis has increased the need for planners to provide good comparative information to decisionmakers. Benefit-cost analysis is a useful tool to compare the economic worth of alternatives and evaluate trade-offs between economic benefits and non- monetizable social and environmental impacts. FHWA has developed a new tool for benefit-cost analysis called the Surface Transportation Efficiency Analysis Model (STEAM), available at: www.ota.fhwa/dot.gov/steam. The software allows development of impact estimates for a wide range of transportation investments and policies, including major capital projects, pricing and travel demand management (TDM). Impact measures are monetized to the extent feasible, but quantitative estimates of natural resource usage (i.e., energy consumption) and environmental impact (e.g., emissions) are also provided. Net monetary benefits (or costs) of alternatives can then be used to evaluate trade-offs against non-monetizable benefits. This paper demonstrates a case study application of the software for a hypothetical medium-sized urban area in the U.S., called Any City.
