Assessment of Winter Maintenance Performance Objectives Using Maintenance Decision Support System

NDOT has made significant investments in winter maintenance operations including the procurement of a Maintenance Decision Support System, acquisition of dedicated weather operational expertise, and the development and refinement of a winter severity index. These resources have improved NDOT’s internal operations, coordination with its partners, and its statewide level of service; however, specific quantification of performance is necessary to maintain and improve NDOT service to its customers. Historically, NDOT has used traffic mobility data to assess performance along the Interstate 80 corridor in terms of speed recovery after a winter storm. This metric has limitations in specifically quantifying NDOT’s winter maintenance operations performance such as its responsiveness to the actions of adjacent state road closures (e.g., Wyoming) and the influence of commercial vehicle congestion when the road initially reopens. Other states have considered metrics such as friction measurements, leveraging camera images to identify time to bare pavement, road condition reports, and more. The proposed project seeks to provide strategic guidance to NDOT in the development of its own suite of performance metrics by conducting an inventory of available weather, mobility, and maintenance data that may be used to create various performance indicators. The project intends to produce sample metrics with the available data and make recommendations on best options and/or additional data needs NDOT may wish to pursue.
