FOREWORD

Since the early 1990s, the term "asset management" has grown to embrace a broad array of tasks and activities aimed at identifying, assessing, prioritizing, evaluating, maintaining, rehabilitating, renewing, preserving, improving, and managing assets. This report addresses asset management of roadway safety hardware in the United States. Increasingly refined and complex tools such as modern bridge and pavement inventory management systems have been developed and adopted by many State departments of transportation (DOTs), as well as some of the larger departments of county and municipal governments. Many of these management systems have been developed cooperatively by pooling funds and in other ways, such as assistance from the Federal Highway Administration (FHWA).

Through maintenance and enhancement efforts, these software systems are growing in their robustness and capability to deal effectively with complex, real-world issues and conditions. One software management area that has not advanced as rapidly is roadway safety hardware inventory, which includes an array of signs, signals, roadway lighting luminaries, support structures for signs, guardrails, pavement markings, and deployed detecting devices—all vital to safe, efficient highway operations.

This study provides information to State DOTs on roadway safety hardware management systems that would help increase their use of state-of-the-practice techniques. This report was developed for State DOT personnel, particularly chief engineers and other top management, involved with the planning, funding, and execution of roadway safety hardware management systems.
