Overview
This case study demonstrates how the National Performance Management Research Data Set (NPMRDS) can be used to measure work zone mobility performance.1 The NPMRDS contains probe-vehicle-based speed and travel time data for major highways and roadways across the United States. The Federal Highway Administration (FHWA) provides the NPRMDS free of cost to State Departments of Transportation (DOTs).2 A real-world road construction project (Texas DOT’s GO I-10 Project in El Paso, TX) is used to illustrate a simple, repeatable process that State DOTs can use to measure work zone mobility performance.
1 Note on work zone safety – This document focuses on work zone mobility performance measurement and management. The authors recognize that work zone safety is paramount and that safer work zones contribute to better mobility performance. However, safety performance measurement and the interplay between safety and mobility is not a focus of this document.
