Abstract:

The Ohio Department of Transportation (ODOT) maintains a Bridge Management System (BMS) which is ; responsible for collecting and maintaining historical and longitudinal data by year for all the bridges in Ohio. The BMS aids ; ODOT in tracking, design, planning maintenance requests on bridges and funds allocation for maintenance. This project ; applied statistical analysis and modeling of the BMS data to provide insights to the rate of degradation and maintenance ; requirement of bridges under different environmental, location and other factors. Age resetting algorithms and Markov ; models were utilized in order to develop Operational Performance Indices (OPIs) forecasting for General Appraisal (GA), ; Wearing Surface (WS), Floor Condition (FC), and Protective Coating Systems (PCS). The results were validated against ; the actual values and the results were very positive. An understanding of the behavior of the existing bridges under the ; effect of different conditions and their future performance is essential for the BMS. Reliable bridge prediction and ; performance models facilitate inspection scheduling, cost analysis and budget optimization.
