TRB’s Transit Cooperative Research Program (TCRP) Report 157: State of Good Repair: Prioritizing the Rehabilitation and Replacement of Existing Capital Assets and Evaluating the Implications for Transit presents a framework that builds upon a set of fundamental concepts and provides a basic set of steps for transit agencies to follow when evaluating and prioritizing capital asset rehabilitation and replacement investments.

In addition to the printed report, an analytical approach and set of spreadsheet tools were developed to support the framework. These tools address how to evaluate rehabilitation and replacement actions for specific types of transit assets, and how to prioritize candidate rehabilitation and replacement actions.

The names of the four analytical tools and links to those tools are as follows:

• The Prioritization Modeling Tool

• The Vehicle Modeling Tool

• Age-Based Modeling Tool

• Condition-Based Modeling Tool

Below are links to the analytical tools that are pre-populated with sample data as examples of how the tools can be used.

• The Prioritization Modeling Tool

• The Vehicle Modeling Tool

• Age-Based Modeling Tool

• Condition-Based Modeling Tool
