Abstract: Today, transportation agencies are working to cope with the challenges of providing an infrastructure that meets the needs of highway users. At the same time, citizens now hold their government, including transportation officials, accountable for the cost-effective and wise investment of their tax dollars. Life-cycle cost analysis (LCCA) is a decision-making tool that highway agencies may use in selecting an optimal pavement preservation strategy. It is the highway agency's responsibility to select the appropriate agency and user cost components to incorporate into a LCCA model. This paper focuses on agency and user cost component models that were incorporated into a risk based LCCA model. A sensitivity analysis was performed on the model output to identify those components that have the greatest effect on life-cycle costs. The highway agency can enhance the LCCA by focusing more detailed data collection and parameter estimation on the model components that were identified as having a statistically significant effect on the model results.
