USDOT plans to preserve 5.9 GHz spectrum for V2X safety

This week, the U.S. Department of Transportation (USDOT) convened leaders from state departments of Transportation, stakeholders in academia, and representatives from the auto industry in Washington, D.C., to discuss the importance of preserving the 5.9 GHz spectrum for transportation safety.

The 5.9 GHz band supports vehicle-to-everything (V2X), a wireless technology that enables data exchanges between a vehicle and its surroundings. Starting with advanced technology development and demonstrations about 20 years ago, America has deployed 54 operational V2X projects, improving safety today, with more in the pipeline.

Vehicle manufacturers are planning to equip new cars with the technology. This next generation of intelligent transportation communications promises to improve safety for drivers and for vulnerable roadway users, such as pedestrians, bicyclists, disabled persons and transit users.

The National Highway Traffic Safety Administration (NHTSA) estimates that full adoption of just two V2X safety applications would prevent about half a million crashes and save approximately 1,000 lives a year. As more safety applications are developed for vehicles, more lives could be saved.

V2X will also support an efficient, safe, and smooth transportation system, with vehicles communicating with traffic lights to improve the flow of traffic. V2X applications such as dynamic traffic signal control and prioritization have the potential to reduce travel times by up to 27% and reduce fuel emissions.
