Abstract:

This project developed a multi-objective optimization for infrastructure management system that can optimize maintenance, repair, and rehabilitation (MR&R) decisions while simultaneously considering agency costs, total vehicle operating costs, and costs associated with safety performance. To do so, models that relate safety (e.g., crash outcomes) to the roadway condition (e.g., IRI) were developed for Pennsylvania and then used as input into a multi-objective optimization framework. The results suggest that considering safety impacts in infrastructure maintenance decision making can significantly change the decisions and their timing.
