Development and Implementation of a Network-Level Pavement Optimization Model for Ohio Department of Transportation

Optimal use of pavement maintenance and rehabilitation budget is essential in a constrained budget environment such as now. This paper presents the development and implementation of a network-level optimization model within a pavement management information system (PMIS) for the Ohio Department of Transportation (ODOT). Future pavement condition is predicted based on historical pavement data using a Markov transition probability model. Such transition probabilities are updated automatically when new condition data become available each year. The network-level optimization model integrates a linear programming model and the Markov transition probability model. This optimization tool is capable of (1) calculating the minimum budget required to achieve a desired level of pavement network condition, (2) maximizing the improvements of pavement network condition with a given amount of budget, and (3) determining the corresponding optimal treatment policy and budget allocations. It can be used by highway agencies as a decision support tool for network-level pavement management decisions.
