Measuring Work Zone Mobility Performance Using the National Performance Management Research Data Set (NPMRDS) – Case Study: Application to the Texas Department of Transportation GO I-10 Project

FHWA is engaging with State Departments of Transportation (DOTs) and conducting research to understand work zone mobility performance measurement best practices, challenges, and opportunities. The information will be used to increase awareness on data, tools, and methods for systematic work zone performance measurement across all stages of project development including planning, design, construction, and post-construction. Topics of interest include use of probe data and mainstreaming performance measures into agency policies and processes, including work zone process reviews and incorporating work zones into transportation system management & operations (TSMO) initiatives. This case study is one of a series of resources on work zone mobility performance measurement. It demonstrates how the National Performance Management Research Data Set (NPMRDS) can be used to measure work zone mobility performance. The NPMRDS contains probe-vehicle-based speed and travel time data for major highways and roadways across the United States. 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.
