The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) provides safety knowledge and tools in a useful form to facilitate improved decision making based on safety performance. While other HSM initiatives have focused on examples of HSM implementation and results of analyses, AASHTO and the Federal Highway Administration (FHWA) sponsored a domestic scan to identify leading practices in the use of the HSM for planning, design, and operations. The objectives of the scan were to: (1) Evaluate the processes, job aids/tools, workforce training, and manner in which state transportation agencies have implemented and integrated the HSM into performance-based processes in planning, design, and operations; (2) Learn the practices of state transportation agencies that have most comprehensively implemented the HSM since its publication in 2010; and (3) Disseminate information about leading practices in use of the HSM in planning, design, and operations to other state and local transportation agencies to help them reduce traffic fatalities and serious injuries on all public roads and make informed decisions to reduce project and operating costs. The scope of this scan extends beyond simply focusing on the implementation of analysis procedures described in the HSM and addresses, more broadly, the implementation of performance-based, advanced safety analyses to facilitate improved decision making. The scan focused on the practices of state transportation agencies that have most comprehensively implemented and integrated the HSM and performance-based, advanced safety analyses in planning, design, and operations in seven areas of interest: Status/Policy; Training; Technical Functions; Data; Cultural; Information Dissemination; and Achieving Performance. This report is intended to help state transportation agencies that have not yet begun to implement the HSM, are beginning to implement the HSM, or are looking to further enhance the implementation of the HSM within their agencies. Most of the recommended actions are also applicable to local transportation agencies and metropolitan planning organizations (MPOs) in similar situations regarding HSM implementation.
