                Reliability of Safety Management Methods: Countermeasure Selection
**Description:**
        High quality data and reliable analytical methods are the foundation of data-driven decision-making. The Reliability of Safety Management Methods series includes five information guides that identify opportunities to employ state-of-the-art (more reliable) methods to support decisions throughout the roadway safety management process. Four of the guides focus on specific components of the roadway safety management process: network screening, diagnosis, countermeasure selection, and safety effectiveness evaluation. The fifth guide focuses on the systemic approach to safety management, which describes a complementary approach to the methods described in the network screening, diagnosis, and countermeasure selection guides. The purpose of the Reliability of Safety Management Methods series is to demonstrate the value of more reliable methods in these activities, and demonstrate limitations of traditional (less reliable) methods.
The Reliability of Safety Management Methods: Countermeasure Selection information guide describes various methods and the latest tools to support countermeasure selection. The target audience includes data analysts, project managers, and program managers involved in projects that impact highway safety. The objectives of the information guide are to 1) raise awareness of more reliable methods, and 2) demonstrate through examples the value of more reliable methods in countermeasure selection. The information guide compares more reliable countermeasure selection methods to traditional methods which are more susceptible to bias and may result in less reliable estimates and less effective decisions. Readers will understand the value of and be prepared to select more reliable methods in countermeasure selection.
The information guide includes five sections. The first section introduces the roadway safety management process and countermeasure selection. The second section provides an overview of various methods related to countermeasure selection. The third section demonstrates the value of more reliable methods compared to traditional methods for selecting countermeasures. Examples highlight the shortcomings of less reliable methods, which may lead to misinformed decisions, non-optimum use of funds, and the implementation of less effective treatments. The fourth section summarizes the data requirements to employ the various methods. The final section describes available tools and resources to support countermeasure selection.
