Guidance on Data Needs, Availability, and Opportunities for Work Zone Performance Measures

Overview

Performance measures quantify how a particular work zone or several work zones together are affecting traveler safety and mobility. In addition, performance measures can help agencies and contractors assess if and how their work zone safety and mobility policies, processes, and procedures are working well or should be improved. In the context of highway work zones, there are three major data needs for performance measurement:

• Performance data (“how much” a work zone affects travelers, the agency, and/or contractor);
• Exposure data (“who” or “what” are being affected); and
• Work zone indicator or stratification data (“when” or “where” the effects are occurring).

This document will look at performance measurement, performance data, and more.
