註釋
"TCRP Report 157 presents the results of Transit Cooperative Research Program (TCRP) Project E-09 related to achieving a state of good repair for transit assets, focused specifically on approaches for evaluating and prioritizing rehabilitation and replacement investments in existing capital assets. The research reviewed existing state-of-good-repair practices in transit and other related industries. Based on the review, an evaluation was performed of the impacts and implications of different investment levels for rehabilitation and replacement of transit assets. The evaluation summarizes the positive and negative impacts of rehabilitation and replacement investment decisions and describes the performance measures used to quantify those impacts. The research developed a framework for transit agencies to use for prioritization of capital asset rehabilitation and replacement decisions. The framework builds upon fundamental concepts involved in prioritizing asset rehabilitation and replacement decisions and provides a basic set of steps for transit agencies to follow. An analytical approach and set of spreadsheet tools were developed to support the framework. The tools address (a) how to evaluate rehabilitation and replacement actions for specific types of transit assets, and (b) how to prioritize candidate rehabilitation and replacement actions. The report presents a detailed example demonstrating application of the analytical approach and tools in support of the framework. Practitioners, researchers, and transit agencies can use the results of the research to better prioritize their investments in existing capital assets and better communicate the predicted impacts of a given set of rehabilitation and replacement investments. This research is the first phase of a two-part research project. The next phase of the research will develop guidance for applying the approach developed through TCRP Project E-09. It includes transit agency pilots and a workshop for testing, refining, and communicating the implementation guidance for evaluating and prioritizing state-of-good-repair investments, as well as development of a set of web-based implementation support tools. This two-part project will help transit agencies evaluate and prioritize capital investments in transit assets for achieving a state of good repair"--Foreword.
