Effectively and efficiently managing a roadway network involves achieving a complex balance between infrastructure, maintenance, operations, safety, and customer service. There are a number of assets crucial to the operation and safety of roadways. While there are established asset management practices for bridges and pavement, there is currently no well-established guidance for traffic and safety assets. The traffic and safety assets explored in this paper include signs, signals, pavement markings/markers, barrier systems, and lighting. This paper focuses on the issues that cut across the management of all of these types of assets, as well as the gaps in the existing knowledge based on a thorough literature review. Furthermore, the transferability and experience in establishing pavement and bridge asset management systems is discussed. The review found that data needs and the uses and applications of the data are two primary types of gaps that exist across these five safety-related assets. The results presented in the paper are based on the results of Phase I of NCHRP 07-21, Asset Management Guidance for Traffic Control Devices, Barriers, and Lighting.
