The purpose of the Countermeasure Service Life Guide is to provide transportation practitioners with the necessary information to make consistent, data-driven decisions for evaluating and prioritizing safety countermeasures using prescribed countermeasure service lives. The target audience includes transportation professionals implementing safety strategies or countermeasures for safety projects or programs. This Guide provides typical service lives for a wide range of safety countermeasures. Further, this guide demonstrates the benefits to standardizing countermeasure service life application throughout an agency. This Guide provides background information on factors that can impact countermeasure service life and analytical considerations when conducting benefit-cost analysis for multiple countermeasures or alternatives with differing service life. Examples demonstrate the application of service life and analytical considerations in various scenarios. A thorough understanding of the time period for which a countermeasure may have a measurable impact is critical to establishing the cost effectiveness of the countermeasure relative to the installation and ongoing maintenance and operational costs. Reliable and consistent approaches are key to inform decisions and improve safety investments.
