Thank you for your interest in Federal Highway Administration’s (FHWA’s) research efforts in developing next-generation pavement performance and asset management metrics and measures. The TA-MAPO Tool was developed as a proof-of-concept tool for cross-asset tradeoff analysis based fundamentally upon benefit cost analysis often used in asset management systems and capital budgeting analytical tools.

Diverse investment candidates are prioritized based on long-term social cost and multiple fiscal scenarios are evaluated. This assists in efficient funding allotments among performance goals, asset classes, and subnetworks to satisfy policy requirements or achieve a set of performance targets while minimizing long term social cost. The tool was conceived as a working prototype, implementable as-is but more likely to be incorporated into tools agencies use or develop to support asset management planning workflow.

The concept and fundamentals of the tool are documented in FHWA’s “Development of Next-Generation Pavement Performance Measures and Asset Management Methodologies to Support MAP-21 Performance Management Objectives,” publication number FHWA-HRT-23-102. A detailed explanation of the tool spreadsheet is provided in Appendix I of the said publication.

System Compatibility

TA-MAPO Tool was developed for and tested in:

• Microsoft® Windows 10 Operating System or later.
• Microsoft® Excel® post-2007 versions in 32-bit and 64-bit.
• TA-MAPO Tool is a Microsoft® Excel® based tool.
