Pavement Network Reliability: Triangular Fuzzy Number and Transited Network Methodology

Many government agencies face the challenge of huge pavement network condition assessment and maintenance planning. Pavement network reliability is essential to conduct efficient pavement network management. This paper proposes a novel model to assess reliability of a large pavement network based on a fuzzy number theory. Weights of roads of the pavement network are comprised of topological connection weight and service weight. A transited network that describes the topological connection relationship between roads in the network is applied to generalize topological connection weights of roads in pavement network. An approximate triangular fuzzy number is proposed to present the network’s reliability. According to a risk factor parameter, the most possible reliability of pavement network, conservative reliability of pavement network, and optimistic reliability of pavement network are presented. The Texas pavement networks of Bastrop, Blanco, Burnet, Calhoun, Glasscock, Hemphill, Kenedy, Lee, Llano, Mason, Milam, San, Saba, Travis, and Williamson counties, made up of 7,717 valid 0.5-mile management sections, are illustrated to validate those models. Results show that proposed models could generalize the reliability of a given pavement network.
