The many challenges facing the WSDOT Highway Maintenance program are continually increasing, stretching WSDOT’s ability to keep highway infrastructure in a good state of repair. Since the mid-1990s, WSDOT Maintenance has been evaluating the effectiveness of its Maintenance Program through outcome-based performance measures, referred to as level of service (LOS). The Maintenance Accountability Process (MAP), as it has become known, is a comprehensive planning, measuring, and managing process that provides a means for communicating the impacts of policy and budget decisions on program service delivery to key customers, including WSDOT executive leadership, the legislature, and the public. The objective of this project is to give WSDOT Maintenance the ability to forecast LOS performance by creating an algorithm to predict trends based on different performance measures across different maintenance activities. Based on a data-driven approach, this algorithm will utilize performance measures to forecast LOS at different investment levels.
