Project Objective
To advance transportation asset management and optimization analysis of roadway safety hardware for improved highway safety performance. The research will focus on three technical aspects of roadway safety hardware management systems as well as pavement, bridge, maintenance, and safety management systems that also handle roadway safety hardware assets:

  1. Inventory process, data collection, performance trend analyses, and needs assessment
  2. Life-cycle cost analyses
  3. System integration to achieve globally optimal, most cost-effective resource allocation decisions

Project Abstract
The U.S. Department of Transportation has identified roadway safety as an over-arching goal. Adequate management of roadway safety hardware assets such as roadway signs; signals; lighting; support and structure for signs, signals, and lighting; guardrails, barriers, and crash cushions; pavement markings and treatments; and deployed detecting devices is a key part to achieve this goal. This study proposes to synthesize the current practice techniques of roadway safety hardware asset management across the country, conduct an in-depth examination of current status of roadway safety hardware asset management programs in Midwest regional states, and develop a methodology for integrating roadway safety hardware asset management into the overall pavement, bridge, maintenance, and safety management systems to assist state transportation agencies in acquisition, maintenance, and upgrade/replacement of roadway safety hardware assets most cost-effectively. The findings will be added to a graduate-level course in transportation asset management at Illinois Institute of Technology.

Task Descriptions
The proposed research will develop:

  1. A method for inventory process, data collection, performance trend analyses, and needs assessment
  2. A method for roadway safety hardware asset life-cycle cost analyses
  3. A method for integration of safety hardware asset management into the overall pavement, bridge, maintenance, and safety management systems.
