Abstract

In 1995, the Federal Highway Administration (FHWA) developed a corridor sketch planning tool called the Sketch Planning Analysis Spreadsheet Model (SPASM). To allow more detailed analysis, FHWA has now developed an enhanced version of SPASM, called the Surface Transportation Efficiency Analysis Model (STEAM). STEAM is highly flexible in terms of the transportation modes, trip purposes, and time periods analyzed. It provides default analysis parameters for seven modes (auto, truck, carpool, local bus, express bus, light rail, and heavy rail) and allows the user to incorporate special circumstances or new modes by modifying these parameters. The user can also provide trip tables for different trip purposes, which will be analyzed separately by the model.
