Transportation Asset Management: Risk-Based Inventory Expansion and Data Needs Assessment

For many years, several State DOTs and local transportation agencies have been concerned with applying asset management techniques to pavements and bridges, with less attention given to roadway ancillary structures such as earth retaining structures, traffic signs and signals, guardrails, lighting, and environmental mitigation features.  In the current economic climate, a growing number of agencies are adopting a more strategic decision-making process for roadway ancillary structures.  Sponsored by the Georgia Department of Transportation and the Georgia Tech University Transportation Center, the objective of this project is to develop a framework to assist with evaluating the relative benefits, costs and risks associated with applying asset management techniques to different categories of ancillary assets.
