U.S. Department of Transportation Website Updated with More Resources and Information on the 5.9 GHz Safety Band

The U.S. Department of Transportation (U.S. DOT) Safety Band website is dedicated to providing detailed information about the 5.9 GHz frequency, a segment of the wireless spectrum that is crucial to the deployment of connected and automated vehicles.

The website has recently been updated with more resources that explore the value and criticality of the Safety Band and its continued use for transportation-related communications between the devices that support connected and automated vehicles and related infrastructure.

The site now features comments given by U.S. Secretary of Transportation Elaine L. Chao at an American Association of State Highway and Transportation Officials meeting on February 26 to discuss upcoming funding and grant opportunities, including some that would rely on the Safety Band. Also available is an informative video covering the harmful impact of bandwidth interference on the safety performance of vehicle-to-everything technology operating in the 5.9 GHz Safety Band.

An article titled “The Safety Band: Separating Myths from Facts” addresses common misconceptions about the Safety Band and the way that connected vehicle communications function via the frequency. Connected vehicles use the interference-free Safety Band for high-precision, low-latency, location-specific communication between vehicles and traffic signals, roadside units, work zones, and even personal devices like smart phones. The technology generates real-time alerts to prevent crashes, manage traffic flow, warn drivers about hazardous weather conditions, or adjust signals to give emergency vehicles priority in congested traffic.

The technology has the potential to dramatically improve our transportation safety and mobility. That is why federal, state, and local governments have invested more than $2 billion to deploy this life-saving technology.

The Safety Band website also features interactive maps that identify where local communities are using the Safety Band for vehicle-to-vehicle and vehicle-to-infrastructure communications. In addition, the website offers fact sheets, technical reports, easy-to-follow presentations, and content from past conferences on the Safety Band.
