Tools That Evaluate Investment Levels and Tradeoffs Performance Tradeoffs Within Investment Categories The FHWA sponsored the development of and continuing enhancements to the National Bridge Investment Analysis System (NBIAS) , an analysis tool for predicting nationwide bridge maintenance, improvement, and rehabilitation needs and measures of effectiveness over a multiyear period for a range of budget levels.

HDM-4 includes a simulation capability featuring pavement deterioration models; application of user-defined standards and criteria for when different project candidates are considered; and calculation of life-cycle agency costs, road user costs, and social and environmental impacts. Washington State DOT has sponsored the development of a prototype multimodal investment choice analysis tool (MICA)

STEAM incorporates risk analysis to describe the level of uncertainty in analysis results. FHWA also has developed a simpler spreadsheet model called SPASM for multimodal corridor analysis on the sketch-planning level, which can be used where travel demand model outputs are not available.

options to limit road occupancy to particular hours of the day or to particular months or seasons of the year. Tools That Monitor Results Performance and Cost Monitoring and Feedback Construction management/estimation systems such as the BAMS/DSS and Estimator products in the AASHTO Trns•port suite have the potential to be used for cost tracking; however, careful planning is required to ensure that meaningful results can be derived from these systems, and a translation process is required to develop unit costs that are usable by most management systems.
