HRSO - Roadside Safety

The Federal Highway Administration (FHWA) Office of Safety Research and Development Roadside Safety Research Program primarily supports the U.S. Department of Transportation’s (USDOT) strategic goal to reduce fatalities and injuries on the Nation’s roadways. The program also serves to enhance efforts to improve safety worldwide. The mission of the Roadside Safety Research program includes the following:

HRSO - Connected Vehicles

The Connected Vehicle (CV) Safety Research program focuses on CV technology, emphasizing safety, coordinated research, development, testing, and deployment of vehicle-to-everything (V2X) components, hardware, and applications under the Intelligent Transportation Systems Joint Program Office’s (ITS JPO’s) CV program. Efforts are directed toward producing products and reports that can be used to develop countermeasures for reducing the number of crashes and improving highway safety.

Research Program Content

Pedestrian Safety in Tribal Areas

Description

The research project will result in a guidebook for infrastructure improvements and safety countermeasures for reducing pedestrian fatalities and serious injuries in rural Tribal areas. The guidebook is for practitioners to prioritize pedestrian safety projects and supports...

Integrating Public Health into Transportation Planning for Federal Land Management Agencies

Description

This research project developed a framework to help transportation planning practitioners at Federal Lands Management Agencies (FLMAs) integrate public health and equity into their work through identified strategies, recommended action steps, and effective practices. This...

Ice Roads Establishment and Management

Description

Ice roads are a common type of transportation corridor in regions of the circumpolar north. They traverse frozen rivers, lakes, and other bodies of water. Every winter, the varied combination of weather, hydrology, and other factors can form ice roads. Experience has shown...

Evaluating the Use of Small Unmanned Aircraft Systems for Inspection of In-Service Steel Bridges

Description

The project identified small Unmanned Aircraft Systems (sUAS) that can collect high resolution condition data while complying with federal aviation requirements and maneuvering through and around all elements of steel bridges, particularly beam and truss elements and...

Emerging Bicycle Technology for Trail Condition Assessment

Description

This project collected high-quality trail condition data in an efficient and cost-effective manner using equipment mounted on a bicycle. The data was processed and used to construct GIS-based trail condition analyses that help guide trail maintenance and project...

Urban Transit to Trails: Mt. Wilson Express Shuttle

Description

The Mt. Wilson Express is a collaboration between the City of Pasadena, Nature for All, and the U.S. Forest Service. This pilot express service will provide Los Angeles County’s first public transportation to the Angeles National Forest between Spring-Fall 2025....

Alkali-Silica Reactivity Mitigation by UHPC Encasement

Description

While many existing strategies can mitigate Alkali-Silica reaction (ASR) distress in new constructions, few available choices are effective in mitigating ASR distress in existing structures. This research will build upon early investigations into the use of Ultra-High-...
