  • Abstract:
    Countermeasure service life is a key input variable to conduct a crash-based cost benefit analysis of potential countermeasures for implementation. Crash-based cost benefit analyses provide users with a quantitative measure for determining which safety area(s) or countermeasure(s) would be most cost effective for reducing the number and severity of crashes in a particular area. The crash modification factor (CMF) Clearinghouse includes a synthesis of countermeasure service lives for various countermeasures. While the synthesis presents a range of service life values for each countermeasure, there is no single national resource that presents typical values of service life for each countermeasure. The Transportation Pooled Fund Study TPF-5(255), Highway Safety Manual Implementation sponsored the development of a Countermeasure Service Life Guide to fill this need. The target audience of the guide is transportation practitioners, such as traffic and safety engineers, designers, planners, and maintenance staff. The Guide provides comprehensive information on selecting and using countermeasure service lives, regardless of a practitioner's experience level. Transportation practitioners will learn about service lives and their relationships to maintenance activities, and how service life can be included as part of a Benefit-Cost Analysis (BCA).The Guide is organized into six chapters, with the focus of the Guide presented in chapters 2-5. Chapter 2 provides an overview of service lives and introduces the benefits of standardized service lives for a BCA. Chapter 3 explains selecting a countermeasure service life for a BCA. Chapter 4 describes the process for identifying and suggesting service lives for countermeasures. Chapter 5 presents BCA examples for single countermeasures where the service life is either known or unknown.
