Tracks: Asset Management

Transportation infrastructure asset management has mostly focused on pavement, bridges, and tunnels. However, traffic signals, Intelligent Transportation Systems (ITS), traffic signs and markings, roadway lighting, guardrails, and barriers are all essential to the safety, mobility, accessibility, and efficiency of the surface transportation network. Furthermore, they will be critical to the reliable functioning of the rapidly evolving Connected/Autonomous Vehicle (C/AV) systems. Many newer vehicles already have limited capabilities for C/AV. Maintenance of these various elements will be even more important as the devices will need to be kept in very good functional condition. Additionally, as the technology rapidly advances, new installations, more frequent maintenance, and upgrades will be necessary to ensure optimum performance. The costs associated with these functions will rise significantly. As funding for maintenance of existing devices and systems has never been sufficient, state and local agencies must be able to demonstrate and justify the need for increased maintenance and replacement. A comprehensive asset management program that links databases of attributes, condition, and expected life-cycle with a work management system detailing maintenance and repairs is crucial. The data provides accurate information as to the scope and overall condition of the various installations, summary of costs over time, projection of scheduled replacements/upgrades, and estimations of future expenditures based on these needs. This presentation examines the challenges and solutions to establishing and sustaining a practical, feasible asset management program for signals, ITS, signs, markings, lights, and guardrails. It is based on the presenter's article in the July, 2020 APWA Reporter. The presenter has 35 years experience in asset management as a Traffic Operations Manager and Public Works Superintendent.
