Strategic Prioritization and Planning for Multi-Asset Transportation Infrastructure Maintenance, Rehabilitation, and Improvements: Phase 2 - Data-driven Decisions from Continuous Monitoring

This project will extend prior work by this team in a first phase of this project, “Strategic Prioritization and Planning for Multi-Asset Transportation Infrastructure Maintenance, Rehabilitation, and Improvements: Phase 1 – Prioritization through Optimization.” This 2-year, first-phase project will wrap up in coming months. Outcomes of the first phase will include: •A deeper understanding of the nature of crowdsourced vehicle response data and its utility, specific to the perception of asset (roadway and bridge) condition, with its impact on free-flow speeds and capacities, and the ability to detect deteriorated conditions through latent space modelling of the data and developed machine learning algorithms; This project will extend prior work by this team in a first phase of this project, “Strategic Prioritization and Planning for Multi-Asset Transportation Infrastructure Maintenance, Rehabilitation, and Improvements: Phase 1 – Prioritization through Optimization.” This 2-year, first-phase project will wrap up in coming months.
