Nevada Department of Transportation Context Classification with Arcadis

Nevada
Nevada Department of Transportation (NDOT), in partnership with Arcadis, successfully developed and implemented a statewide Context Classification Program to support transportation planning, design, safety, and asset management activities.

Integrated Pavement Friction Management & Safety Performance Framework

Illinois
This project develops an integrated, network-level pavement friction management framework for Illinois. It transforms friction, traffic, and pavement characteristics into crash-risk measures and integrates them with life-cycle cost analysis to support proactive pavement management decisions.

Leveraging Delivery Mechanisms – Road Reconfigurations Through Resurfacings

Georgia
A common DOT challenge is need that exceeds available funding. GDOT’s Safety Program works with the Resurfacing Program and leverages On-Call Requests (OCR) to deliver road reconfigurations – reducing costs and accelerating timelines on improvements for vulnerable road users and speed management.

Nebraska’s Interstate Cable Median Barrier Success

Nebraska
Nebraska implemented cable median barrier on a few segments of Interstate 80. We have observed a reduction in fatalities and serious injuries from cross-over median crashes. The poster will also include cable median barrier strike and repair stats to show the maintenance perspective with safety.

Systematic Approach to Illinois’ Pavement Friction Management

Illinois
Illinois DOT developed a comprehensive program to integrate pavement friction and safety into treatment and asset management decisions. It includes a friction management program, treatment toolbox, and educational materials.

A Comprehensive Approach for Friction-Enhancing Treatment Selection

Kentucky
Kentucky replaced a needs-based, hot-spot approach with a more precise, systemic, “solutions-based” approach to friction-enhancing treatments and improved pavement safety performance.

Oklahoma Safety Performance Measures

Oklahoma
Oklahoma DOT uses safety performance measures to identify and address safety issues like roadway departure, wrong-way driving, and work zone safety.

Data for Proactive Road Safety: Continuous Pavement Friction Measurement

Kentucky
Pavement Friction Management (PFM) using Continuous Pavement Friction Measurement (CPFM) is a proactive approach for managing pavements for safety throughout the roadway lifecycle. Taking a lifecycle approach to designing, specifying, and maintaining friction performance saved Kentucky more than $1 billion annually and reduced fatal and severe crashes by up to 24%.

Pavement Marking Retroreflectivity

FHWA
The Final Rule on maintaining pavement marking retroreflectivity goes into effect September 6, 2026. Agencies can use recommended methodologies to better prioritize budgets, maximize the life of pavement markings, and improve roadway safety.

Making Safety Everyone’s Business: Integrate Safety into All Programs and Projects

FHWA
FHWA has several resources and examples of integrating safety into all transportation projects, throughout the project lifecycle, from planning through operations and maintenance. They also have resources for organizational safety culture and programmatic safety integration.
