Performance Measurement Examples

Agencies have developed numerous methods to measure and monitor work zone performance and have also implemented web-based resources to inform the public about the performance of roadway projects and the transportation system as a whole.

Measuring and Monitoring Work Zone Performance

State-Specific Examples

  • 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 (HTML, PDF 2MB)
    This case study 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.
  • A Policy-Driven Approach for Work Zone Mobility Performance Management (HTML, PDF 2MB) - The Ohio Department of Transportation (ODOT) uses a policy-driven approach to systematically determine any negative impacts that work zones may have on mobility, and eliminate, minimize, or mitigate those impacts to the greatest extent practicable. The objective of the department's effort is to enhance work zone mobility and safety while delivering a positive road user experience.
  • Comprehensive Work Zone Mobility Performance Management Across Project Stages (HTML, PDF 819KB) - The California Department of Transportation (Caltrans) uses its Performance Measurement System (PeMS) to estimate work zone impacts, plan closures, manage performance during construction, and evaluate effectiveness of work zone management practices post-construction.
  • Missouri DOT I-64 (US 40) Full Closure Performance Tracking - Missouri DOT (MoDOT) used full closure to complete the $535 million reconstruction of Highway 40 (Interstate 64) in St. Louis in two years, rather than the originally estimated six to eight years, and at lower cost. MoDOT established incentives for the Contractor that included timely completion and re-opening of the road, and tracking and meeting performance indicators for regional mobility. MoDOT also completed an in-depth evaluation of the impacts from and satisfaction with the closure approach.
  • Missouri DOT Tracker - Tool to assess how well Missouri DOT (MoDOT) delivers services and products to its customers. The Tracker is divided into 18 performance measures, based on MoDOT's Mission and Value Statements. Several of the measures relate directly to work zones, such as ratings from an online survey MoDOT uses to gain driver feedback on visibility and traffic flow in its state highway work zones.
  • Regional Transportation Commission of Southern Nevada FAST Dashboard - The Freeway and Arterial System of Transportation (FAST) Dashboard is Southern Nevada's freeway performance monitoring and management system. It enables the Nevada DOT to evaluate operational issues related to work zones, incidents, special events, and daily recurring congestion, and the effectiveness of activities to manage the impacts. It also enables the public to view real-time and historical travel time and performance information in a wide variety of user-selectable and user-customizable displays.
  • Ohio DOT Crash Analysis (HTML, PPT 1MB) - The Ohio DOT (ODOT) "Real-Time Work Zone Crash Data Analysis" compares historic, pre-construction crash data verses crashes occurring when a work zone is in effect. The ODOT database breaks the work zone into half-mile segments, sorts the crashes into their proper segment, and performs a "before-after" comparison of the pre-construction and construction crash frequencies for each half-mile segment. ODOT examines areas that show elevated work zone crash frequencies to make improvements in current work zones as well as in future work zone management practices.
  • Oregon DOT Performance Monitoring
    • Dynamic Work Zone Traffic Management (PDF 340KB) - May 2010 ITE Journal article that describes how Oregon DOT has recognized the benefits of using smart work zone technology, including how real-time and near-real-time traffic data collected using this technology can be used by construction and management personnel to monitor the status and performance of a work zone.
  • Texas DOT Performance Monitoring - The Texas Department of Transportation (TxDOT) has identified key work zone safety and mobility performance measures to target as part of a work zone monitoring program within a district, region, or across the state.
  • Virginia DOT Work Zone Safety Checklist (PDF 237K) - Provides a consistent and helpful way to review and document temporary traffic control inspections of construction, maintenance, utility, and permit work zone operations. The checklist enables work zone deficiencies to be noted and detailed information provided to allow rapid and thorough correction of the problem.
  • Utilizing Probe-Vehicle Data for Work Zone Mobility Performance (HTML, PDF 1.1MB) - The Virginia Department of Transportation uses probe-vehicle-based performance measures to estimate work zone related delay and queuing at the State, district, corridor, and project levels.
  • Washington State DOT Performance Measures Library - Library listing online performance measurement and strategic planning mechanisms for 51 state, commonwealth, and federal district transportation authorities and other notable performance reporting by city, county, and regional entities.
  • Wisconsin DOT: State DOT Performance Measurement for Highway Design and Construction - Synthesis of published performance measures in the areas of highway design and construction, developed as a means to help gauge current State DOT practices in this area.
