About ChORUS

The Clearinghouse for Older Road User Safety (ChORUS) is a collaborative project of the Roadway Safety Foundation and two leading information technology developers, Syneren Technologies and Bonzzu. Support is provided by the U.S. Department of Transportation’s Federal Highway Administration (FHWA) and National Highway Traffic Safety Administration (NHTSA).

ChORUS serves as a centralized, user-friendly, and dynamic source of information pertaining to highway safety for aging drivers, passengers, pedestrians, and cyclists. Built as a comprehensive resource, it covers all three major components of highway safety: safe roadways, safe road users, and safe vehicles.

Safe Roadways

Communities across the country can realize tremendous safety gains by implementing proven and cost-effective design features and crash countermeasures on their roads. From retroreflective signage that helps older drivers navigate at night, to high-visibility crosswalks  that allow drivers to more easily see pedestrians, to left-turn lanes that improve sight distance at intersections and prevent deadly right-angle crashes, infrastructure solutions are integral to enhance safety for the aging road user. ChORUS therefore provides quick and easy access to design guidelines for the aging population, technical documents, case studies and success stories, and information about innovative financing solutions.

Safe Road Users

Whether traveling by private automobile, public transit, bicycle, motorcycle, or foot, all of us share the same goal of getting to our destination safely and efficiently, and older drivers exhibit some of the highest rates of seatbelt use and lowest rates of distracted or impaired driving. ChORUS includes a wealth of information designed to support aging drivers, from self-assessments and links to refresher courses, to state-specific licensing information. Recognizing that driving is simply not an option in all cases, the Clearinghouse also promotes safe cycling and walking, provides support for families and caregivers concerned about their loved ones, and highlights alternative transportation options that may be available.

Safe Vehicles

The greatest risk to aging drivers is fragility that makes crash survival and recovery more difficult. As such, this is a group that especially stands to benefit from vehicle safety technologies both emerging (e.g., forward collision mitigation) and familiar (such as well-designed crumple zones). ChORUS promotes safer vehicles for seniors by featuring a range of consumer-friendly information, from education on how to interpret safety and crash ratings, to overviews of cutting-edge technologies, to simple tips on helpful features to look for in any car (e.g., wider mirrors). It also includes a wealth of resources for researchers, engineers, industry, the media, and others who help advance vehicle safety.

Our Partners

The Clearinghouse is a program of the Roadway Safety Foundation and a diverse group of partners, and includes input from a panel of subject matter experts (SMEs), and review by the US DOT. Our partners include:

Federal Highway Administration

The Federal Highway Administration (FHWA) is an agency within the U.S. Department of Transportation that partners with and supports State and local governments in the design, construction, and maintenance of the Nation’s highway system (Federal Aid Highway Program) and various federally and tribal owned lands (Federal Lands Highway Program). Through financial and technical assistance to State and local governments, the Federal Highway Administration is responsible for ensuring that America’s roads and highways continue to be among the safest and most technologically sound in the world. FHWA, through a cooperative agreement with the Roadway Safety Foundation, provides input on ChORUS content, tools, and programs related to safer road designs and best practices for improving community safety through infrastructure enhancements.

National Highway Traffic Safety Administration

The National Highway Traffic Safety Administration (NHTSA) was established by the Highway Safety Act of 1970 and is dedicated to achieving the highest standards of excellence in motor vehicle and highway safety. It works daily to help prevent crashes and their attendant costs, both human and financial. Through a contract with Syneren Technologies, NHTSA is responsible for ChORUS information and resources pertaining to its areas of expertise, notably driver behavior initiatives and motor vehicle safety (including recalls).

Syneren Technologies

Syneren is an award winning, CMMI Level 3 certified, high quality provider of technology solutions for the government as well as commercial sectors.
