Abstract:In 2007, the Road Weather Management Program (RWMP) conducted a study with stakeholders from the transportation and meteorological communities to define eleven performance measures that would enable the Federal Highway Administration (FHWA) to determine the extent to which its goals were being met. In 2010, FHWA led a task to quantify these performance measures. This report documents a follow-on task to update these performance measures using information which became available since 2012. The focus of this update includes: (1) reviewing existing measures for their continued suitability, strengths, and weaknesses for assessing performance, (2) determining changes to the baseline conditions for existing measures using updated and new data sources, (3) incorporating new performance measures around reliability, the operations efficiency index (OEI), Moving Ahead for Progress in the 21st Century Act (MAP-21), and Safe, Accountable, Flexible, Efficient, Transportation Equity Act – A Legacy for Users (SAFETEA-LU’s) Section 1201 rule, (4) identifying refinements necessary to the existing performance measurement framework and developing a plan to quantify the measures; and (5) quantifying all existing and new performance measures using current data to create a 2012 RWMP performance assessment report. The following document includes a discussion on the background for the development and update of RWMP performance measures, the evolution of the measures since 2007 including the approach and data sources used, a description of each RWMP objective and the quantification of each associated measure, and an overall assessment of the RMWP based on the performance measures tracked.
