About the research

In recent years, risk-based management of infrastructure assets has gained precedence in infrastructure asset management. The Moving Ahead for Progress in the 21st Century Act (MAP–21), aligned with this progress, requires state transportation agencies to incorporate risk-based management in planning systematic preventive maintenance, replacement, or rehabilitation decisions for their bridge networks. However, the legislation does not provide guidance on a methodology; states are flexible in what type of methodology they choose or how they define risk. At present, state agencies are challenged by identifying and quantifying these risks and developing procedures to address these risks at the network level. The proposed research will tackle these issues focusing on regional risks and working with state transportation officials in the region. The research team will identify risks, model and quantify them, and ultimately develop a methodology to incorporate all risks into decision making at the network level. While the research will focus on regional risks and expertise, the resulting methodology will be exemplary for all state transportation agencies.
