INDIANA'S APPROACH TO A BRIDGE MANAGEMENT SYSTEM

Indiana approached the development of a bridge management system with the requirement to utilize the current bridge inspection data collected under the guidelines of the National Bridge Inventory standards. There are four core modules of the system that run sequentially. The four modules are decision tree (DTREE), economic analysis (COST), ranking (RANK), and optimization (OPT). The objective of DTREE is to analyze condition and geometrical data selecting representative actions over a five-year time window, updating condition ratings dynamically by the Markovian process. The COST module uses recommended actions, costs and action years from DTREE to perform life-cycle cost analysis. The RANK module selects projects in priority order based on a weighted criteria to maximize effectiveness of investment, bridge condition preservation, and bridge traffic safety, and minimize negative community impact. Utility curves were derived for these criteria to measure effectiveness (benefit) based on the difference in utility values from the projected bridge condition at the time of proposed construction, to the utility value of the proposed bridge improvement. Selection of projects can be made by selecting projects of the highest effectiveness until funds are expended. The OPT module uses the output from the RANK module to select bridges with the greatest total effectiveness. Thus, the effectiveness is the improvement in overall disutility of the bridge. The intent of the optimization process is to maximize the system effectiveness and minimize the cost while staying within the proposed budget.
