Risk-Based Optimization Methodology for Managing County Paved Roads

A Pavement Management System (PMS) is a strategic and systematic process to maintain, and upgrade the road network. When funding is limited, it is very important to identify the best mix of road preservation projects that provide the most benefits to society in terms of overall life cycle cost of the road network. The most common factors that play an important role for identifying projects are: budget, traffic volume, Present Serviceability Index (PSI) and risk associated with selecting treatment types. This research develops an optimization methodology for county paved roads that identifies the best mix of preservation projects within budget maximizing traffic (passengers and trucks traffic) on treated roads, maximizing the weighted average PSI, and minimizing the risk. This methodology will facilitate a statewide implementation of PMS for counties in the state of Wyoming.
