Developing an Optimization Model for Managing County Paved Roads (Year 2)

In the state of Wyoming, there are a total of 27,831 miles of roadway owned and maintained by federal, state, and local entities. Approximately, 63 percent of these roads are maintained by local governments. Approximately, 15 percent of these local government roads are paved while the rest are unpaved. According to Moving Ahead for Progress in the 21st Century Act (MAP-21), each state is required to develop a Pavement Management System (PMS) to improve or preserve the present pavement condition and the performance of the system (FHWA, 2014). All state departments of transportation (DOTs) already have their own pavement management systems. The Wyoming Department of Transportation (WYDOT) utilizes their PMS to maintain 6,844 miles of interstate and state highways. Currently, there is no PMS or road maintenance database for the 63 percent of roads maintained by Wyoming local governments. In a recent study by Huntington et al, 2013, a recommendation was made to establish a pavement management system for local roads. This proposal concentrates on establishing an optimization procedure for managing the 2,550 miles of county paved roads. The proposed PMS for county roads will be developed considering local factors and traffic conditions which are significantly different from the state managed roadways (Wolters, Zimmerman, Schattler, & Rietgraf, 2011). Any PMS consists of two basic components: a comprehensive database and a set of tools or methods that can assist decision makers in establishing cost effective strategies for evaluating and maintaining pavements. The comprehensive database should contain current and historical information on pavement condition, structure, and traffic. The set of tools or optimization techniques will determine existing and future pavement conditions, predict financial needs, as well as identify and prioritize pavement preservation projects. In 2014, WYDOT and the State Transportation Innovation Council (STIC) funded a research project to develop a comprehensive database for county paved roads. As part of that study, a comprehensive data collection effort was conducted by the Wyoming T2/LTAP center to collect roadway inventory data, traffic counts, roadway widths, pavement condition data and roadway thickness. This proposal seeks to develop the second component of PMS which includes developing a set of tools to optimize the conditions of county paved roads.
