Welcome to Road Weather Management
Road Weather Management Capability Maturity Framework (Workshop and Tool)
Transportation agencies can avail of a facilitated workshop and/or use the electronic tool on their own to conduct Road Weather Management Capability Maturity assessments. The Capability Maturity Framework workshop and electronic tool will evaluate the agency’s ability to effectively manage operations during adverse weather conditions. When the existing capability levels are determined, a list of concrete actions is created for agencies to raise their capabilities to the desired levels. To schedule a workshop, contact Roemer Alfelor at email@example.com or 202-366-9242.
Road Weather Management Performance Measures: 2015 Update
The Road Weather Management Program (RWMP) continues to conduct a periodic review of its performance indicators to ensure that the performance measures reflect the changes in program objectives as well as the broader policy context. The 2015 Road Weather Management Performance Measures Report is the next iteration of this periodic review of the RWMP's performance and an update to the 2012 report.
Weather Responsive Traffic Management (WRTM) Implementation Projects
The FHWA Road Weather Management Program published the final reports and flyers for three recently completed WRTM Implementation Projects with
- Wyoming DOT (Report (PDF 3.27MB), Flyer (PDF 838KB),
- South Dakota DOT (Report (PDF 4.3MB), Flyer (PDF 1.2MB), and
- Michigan DOT (Report (PDF 7.41MB), Flyer (PDF 2.25MB).
The purpose of these projects is to develop, implement and evaluate weather responsive traffic management (WRTM) strategies that utilize mobile road weather data (using field devices and vehicles) for traveler information, traffic control and winter maintenance activities.
Benefit-Cost Analysis for Road Weather Management: Compendium and Briefs
The FHWA Road Weather Management Program published a Compendium and two Technical Briefs on Benefic Cost Analysis (BCA) for Road Weather Management (RWM). This compendium provides detailed guidance on benefit cost analysis for transportation operations with a focus on Road Weather Management Strategies, and presents seventeen case studies. The technical briefs (1 and 2) summarize the application of BCA concepts and tools to RWM as well as the examples that are found in the compendium.
Third National Stakeholder Meeting on Weather Responsive Traffic Management: Summary Report
The meeting took place last October in Kansas City. It continued the FHWA dialogue and engagement with the stakeholder community on advancing the state of the practice in WRTM, building off the success of the first two meetings held in 2011 and 2013. This report summarizes multiple aspects of the meeting including the Kansas City Scout tour, the presentations, discussions, recommended action items, and feedback.
Citizen Reporting of Current Road Conditions
The Citizen Reporting of Current Road Conditions best practices document reviews, compares, and contrasts citizen reporting programs that capture current weather and road conditions at five state departments of transportation - Wyoming, Utah, Idaho, Iowa, and Minnesota.
Concept of Operations for Road Weather Connected Vehicle Applications
This document (PDF 3.3MB) contains various Concepts of Operations (ConOps) for connected vehicle-enabled road-weather applications. The ConOps are intended to expand the amount of data used to assess, forecast, and address weather impacts on roads, vehicles, and travelers.

Adverse weather conditions have a major impact on the safety and operation of our Nation's roads, from signalized arterials to Interstate highways. Weather affects driver behavior, vehicle performance, pavement friction, and roadway infrastructure. Weather events and their impacts on roads can be viewed as predictable, non-recurring incidents that affect safety, mobility and productivity. Weather affects roadway safety through increased crash risk, as well as exposure to weather-related hazards. Weather impacts roadway mobility by increasing travel time delay, reducing traffic volumes and speeds, increasing speed variance (i.e., a measure of speed uniformity), and decreasing roadway capacity (i.e., maximum rate at which vehicles can travel). Weather events influence productivity by disrupting access to road networks, and increasing road operating and maintenance costs.
- Road Weather Management Web-Based Courses - FHWA and the Consortium for ITS Training and Education (CITE) are now offering three interactive web-based courses: (1) Principles and Tools of Road Weather Management, (2) RWIS Equipment and Operations, and (3) Weather Responsive Traffic Management. A new Road Weather Management Certificate is also being offered to those who will complete these three core RWM courses and additional elective courses on ITS. Information about the 2014 Road Weather Management Courses (which are currently offered free for transportation agencies) can be found at http://citeconsortium.org/courses/2014Blended_RW_021114.pdf (PDF 144KB).
- NWS Web-Based Training - FHWA and the Cooperative Program for Operational Meteorology, Education and Training have developed a web-based training course for road weather management staff to learn about National Weather Service products, forecasts and warnings.
