The U.S. Federal Highway Administration’s Work Zone Mobility and Safety Program has released a primer designed to assist transportation agencies in establishing and monitoring a useful set of work zone safety and mobility performance measures.
The primer includes guidance on project-level and agency program-level performance measure needs, defines a number of possible work zone performance measures that agencies can use, and describes the methods and technologies that are available to gather data to monitor them.
The primer also outlines procedures on how to calculate specific performance measures from different types of work zone traffic monitoring data, and on use of the measures across multiple projects to assess compliance to agency policies and goals.
