The objective of this research is to develop asset management guidance for selected categories of traffic and safety assets that are owned and maintained by an agency. The selected categories are signs, traffic signals (including beacons, flashers, and ramp meters), markings, barrier systems (including guardrails, end treatments, and impact attenuators), and lighting. Additional emphasis will be placed on asset management processes, procedures, and tools that will help departments of transportation (DOTs) to operate their traffic signal systems at maximum efficiency. |
