An Optimization Framework for Pavement Treatment and Spatio-Temporal Distribution of Work Zone Closures
Year: 2025
Type: article
Abstract: Departments of transportation (DOTs) are responsible for maintaining the roadway network at certain pavement levels and operational performance. While these two metrics are often looked at separately, we developed a framework in a previous study that integrates pavement and operational considerations and allocates for the interaction between them. This paper expands on the developed framework to zoom in on a work zone allocation module that better represents realistic operations and constraints while making decisions at the network level. The focus of this paper is on the development of a systematic and comprehensive methodology to optimize the allocation of networkwide pavement treatment work zones over space and time. We propose a novel adjacency function that can be used as a surrogate measure for the network travel time obtained from a full-scale simulation run. Our findings confirmed the hypothesis of the strong relationship between the travel time obtained from the developed adjacency function and that obtained using full-scale simulation. The predicted versus actual plot shows a high R squared value of 0.96, which is a good indication for using the adjacency function for computing network travel time in lieu of running full-scale simulation.
